You haven't set the values for the systems in the second block of code.

If you want to get the file name from the user and then open that file do this [code=c++] #include <string> #include <iostream> #include <fstream> using std::string; using std::cout; using std::cin; using std::ofstream; int main() { string filename; cout << "Please enter the filename: "; cin >> filename; ofstream fout(filename.c_str()); …

The problem is that when you find a new max or 2nd max you need to reset the counter back to 1.

Look at this [code=c++] // defenition int getNumAccidents(string) // decleration int getNumAccident(string name) [/code] (hint) See how the ( don't line up.

You cant do that in c++. All variables must be declared before compilation. if you want to get n inputs you will either need an array or some sort of container like a vector.

I think what you are looking for is a 2d vector. If that is what you are trying to do than to declare a 2d vector use [code=c++] std::vector<std::vector<string> > rows; [/code]

A bool can be thought of as an int with a range 0f 0 to 255. As such a 0 means false and anything else is true.

Ell you can only return one variable. If you want to return information from your function to more than 1 variable you will need to pass the variable into the function by reference or a pointer. That said I think a reference will be fine for you. See how this …

Lines 27 and 31 are incorrect. You have [code=c++] if(nametag == "lastname" || "surname") // which translates into if(nametag == "lastname" || true) // which translates into if (true) [/code] What you need to do is [code=c++] if(nametag == "lastname" || nametag == "surname") [/code]

Tell the person you are programing with that this is c++ not java. Creating a class that is just holding the math functions is unnecessary. You can just call them when you need the without having the overhead of creating a class.

What happens if you remove your call to sort?

well you need an ofstream object opened to the file that you want. after you do that in for loop output the char array to the file using the >> operator.

Do you want to round the number? Like 3.7 becomes 4 but 3.2 becomes 3 or do you just want to drop the decimal part? If you just want to drop the decimal part you could do [code=c++] double doubleArray[60]; int intArray[60]; for (int i = 0; i < 60; …

The modulo operator is the remainder operator. it says what is left after I divide x by y. So if you do 10 % 2 you get zero because 10 / 2 = 5 with nothing remaining. If you do 10 % 4 you get 2 because 10 / 4 …

Use a char array and a for loop. Store the input into the array and loop through it to find the largest number.

line 52 should be [icode]Stack g;[/icode]. The reason for this is the compiler is interpreting line 52 as a function that returns a Stack and takes no arguments.

What are you trying to do where you need these functions?

Line 9 cant be blank because you have to do something with the parameters you pass it. Lines 23-24 are there to compare a double value against the volume of the box.

in main you would do [code=c++] intList.reversePrint(cout); [/code]

In between lines 5 and 6 try adding [code=c++] timestamp.erase(timestamp.end() - 1); [/code]

To get the last letter from a file you would use [code=c++] //... ifstream fin("input.txt"); fin.seekg(ios::end); char ch; fin >> ch; if (ch == '+' || ch == '*') //... [/code] Also it is bad practice to use the goto command

If you can use STL then you could use the random shuffle algo. Since I don't think you can use that algo you would need to use two for loops. One to populate the array with the numbers 1-20 and the other to swap the elements in the array around. …

please post the code you are using right now

Hey all, I was taking a look at my stringstream conversion function and I couldn't decide how I want to handle a bad conversions. I used an exception and then in main I would a use a try, catch block to get any exception. [code=c++] #include <sstream> #include <exception> class …

I believe the reason for this is the or in the while condition. If you change it to and it will work. If I remember correctly this happens because the compiler evaluates the whole statement and causes a false negative. I know there is a post on here about this …

the reason he has it returning the an istream reference is to be able to chain it. by that I mean [code=c++] cin >> input >> anotherInput >> read_hw(cin, homework); [/code]

To follow WaltP's adive you could simply do [code=c++] srand(unsigned(time(0))); string names[] = {"Jim", "Tom", "Jeff", "Larry"}; cout << "The person that should drive is: " << names[rand % 4] << "."; [/code]

Are you supposed to implement your own list class?

You might be able to do something like this. [code=c++] //... if((strcmp(token[0], "PRISM") == 0)) { if((prismSide1 = atof(token[1]) = 0.0); run error code if((prismSide2 = atof(token[2]) = 0.0); run error code if((prismSide3 = atof(token[3]) = 0.0); run error code prismCalc(prismSide1, prismSide2, prismSide3); } //if //... [/code] Personally I would …

well if that is the only data in the text file and there is a space between the : and the info you want then it is pretty simple. You read in the first part of the line into a dummy variable and then the you read in the second …

look at this part of your code [code=c++] for(int n=0;n<11;n--) [/code] What happens to n as the loop goes on? Does n ever become greater than or equal to 11? Your else statement is also wrong. Have you ever seen [icode]else[/icode] followed by a condition? [URL="http://www.intap.net/~drw/cpp/cpp04_02.htm"]here[/URL] is a link for …

What are the error that you are getting?

If you are checking that data inside the containers against the supplied response then you might want to think about using templates. Here is a simple way to check through containers using iterators. [code=c++] template<typename ForwardIterator> void CheckResponse(int response, ForwardIterator first, ForwardIterator last) // last should be one past the …

The problem with your algo is that when you get to numbers like 15 which are divisible by both 3 and 5 you add it in twice. I think a a better way would be to use one for loop from 3 to 1000 and check with an if statement …

The second is invalid. Only a pointer to can use the new operator. Here is a little breakdown for you. [code=c++] int foo = 10; // normal assignment; int *fooPointer = new int; *fooPointer = foo; // now fooPointer is a pointer to an int that holds the value of …

The way I would go about this is to use a prime number function. Then use a while loop to keep track of how many sets of primes you have found [code=c++] bool isPrime(int number) { // put code here to check if a number is prime; } int main() …

When you declare an array or a vector you don't subtract one from the size when you declare it. [code=c++] int foo[30]; // creates a array of size 30 indexed from 0-29 vector<int> bar(30); // creates a vector of size 30 indexed from 0-29 [/code] if you do [code=c++] int …

I would have to agree with caut_baia that we need to see find_original and also some more of your code.

you need to change your function decleration on line 8 to [code=c++] void Read_Data(ifstream &, string[], double[], double[], double[], double[], double[]); [/code]

you need to reset your i variable back to zero after your for loops that start on lines 8 and 34. By the way what exactly are you trying to accomplish here?

well to keep kicking the dead dog. Fboady it is true that a 32bit int is aprox -2 bil to 2 bil but 100! is 9.3326215443944152681699238856267e+157 which is way out of range for an int on even a 128 bit system.

since a and b are pointers you need to use the -> operator not the . operator

Please post an example of what you are trying to do

What are you trying to do with it? Also please use code tags when posting code. I would also change your for loop to [code=c++] for (size_t i = 0; i < str.size(); i++) { //... } [/code]

on lines 64 through 67 you are passing the drivers address to the functions but you defined the functions as taking a driver by value. Here is the different ways you can pass an argument to a function. [code=c++] #include <iostream> using namespace std; int PassByValue(int value) { return value …

What is user input declared as? It looks as if you a re trying to use an initialize list. Make sure your compiler is able to use that feature if that is what you are doing.

Why are you including a .cpp file? The general structure of the the files should be like main.cpp: This is the cpp file where main is. You can call it anything. In this file you will include all header files needed className.h: This is where the declaration of the class …

line 29 should be [icode]total = total + price[count];[/icode]. What [icode]total = total + price[/icode] does is say add total to the address of the first element in prince and then store it in total. You cant do that because total is a double. What I did say to add …

Use std::vector<std::string>

What happens if you try this [code=c++] CDirLoader::GetFileExtHandle(not related params) { std::string prefDir; for(size_t i=0;i<preferredPaths.size();++i) { if (!preferredPaths[i].empty()) prefDir = preferredPaths[i]; //... } } [/code]
