In the second example your creating an array of pointers which in your case are 8 bytes.

In C structures can hold pointers which can point to functions...So in a way, C structures can hold(point to) functions..

Please enclose your code with the proper tags [code] #include<iostream> using namespace std; struct BankAccount { int accountNum; double accountBal; double rate; }; int main() { const int ACCOUNT = 5; BankAccount info[ACCOUNT]; int sub; double balTotal = 0; double balAverage; int accountNumber; bool isFound = false; for(sub =0; sub<ACCOUNT …

This might move along faster if you posted specific problems..

Please read the click below The exec() family of functions replaces the current process image with a new process image. The functions described in this manual page are front-ends for execve(2). (See the manual page for execve(2) for further details about the replacement of the current process image.) This exert …

std::cout is interpreting c as a character string...You know something that ends with a '\0'. If you want the address try this: [code] std::cout<<(void*)c<<" "<<*c<<std::endl; [/code]

I didn't notice an if statement.....It could be said that was the only thing that didn't have any errors...What compiler are you using? [code] #include <iostream> #include <cmath> using namespace std; int main (void) { float Height, Radius, BoxHeight, BoxLength, BoxWidth, SiloVolume, BoxVolume, BoxVolumesum = 0, Grainleft; char choice = …

It means (*filterdata).Q_angle = Q_angle;

Take this out of your header file long addresses[5]; and put it in your main executable... When you compile def.c you create a label called addresses and when you compile mainfile.c you create another label addresses. When you bring both files together for the final executable it fails because addresses …

Could you post a brief example of the data files...

You can use EOF by pressing Ctrl-Z in Windows or Ctrl-D in Linux....Here's an example [code] #include <iostream> #include <string> int main() { std::string word; std::cout << "Please enter a string of words...EOF to exit" << std::endl; while ( std::cin >> word ) std::cout << "program recieved->" << word << …

What is Info record;

this 'monday' should be "monday" Strings are enclosed with double quotes not single quotes... If your learning C++ then please get yourself a good book on the subject...Tutorials just don't cut it.

You'll probably find the answer in here [url]http://www.iecc.com/linker/[/url]

Jeez I tried googling LUA and C++ and found this [url]http://csl.sublevel3.org/lua/[/url]

Well how do you define the structure in the second example? Maybe that's a little vague...How do you define the memory layout in the second example? In the first example you have sizeof(int) plus sizeof(struct node *n1) plus padding. In the second example what is the sizeof(struct node)? Its impossible …

Can we see the define of the structure?

Try using unsigned int...How is ReadBuff defined?

Try passing the address of newData... [code] computeFibonacci(&newData); printFibonacci(&newData); [/code] Also this: [code] int computeFibonacci(); int printFibonacci(); [/code] should be: [code] int computeFibonacci(shared_data*); int printFibonacci(shared_data*); [/code]

Const iterators are used to indicated that the underlying object data members will not change.

If I was writing this this I would strive for simplicity. Have the user enter a value and then have the computer guess 50, the program should respond by indicating higher or lower(or correct). The computer then should take the set above or below and pick a middle value...etc...etc. Example: …

You had a few typos in your code...You really should write a small part of the program compile/debug and then move on. [code] #include <iostream> using namespace std; int ScrabbleScore(string word) { int x = 0; int index = 0; while (word[index]) { char ltr = toupper(word[index]); std::cout << "char->" …

Can we see the constructors of the class Mixed?

Your array is of type int not float. Plus your for statements are wrong.

Try this [code] #include <stdio.h> #define j 2 int main(void) { int i; switch (i) { case 1:break; case j:break; default:break; } return 0; } [/code] or [code] #include <stdio.h> enum choices {a, b, c}; int main(void) { int i = 0; fputs("enter a value->", stdout); fscanf(stdin, "%d", &i); switch …

You haven't allocated/assigned any memory for answer...

How about giving us a hint with some code....

You could use p1->lastName p1->firstname

You know this is written in C not C++...

[QUOTE=Eagles36;1348353]I want to know how to create a makefile so that I dont have to type in the files I am linking together. Also is it possible to use a make file which will run two files. I have a fraction.h file and fraction.cxx (implentation file) I have a main.cpp …

You need to pass a pointer to a pointer for this to work... Your function should be declared like. [code] void teste(int **p_int) [/code] and you should pass your pointer like [code] teste(&m); [/code] The reasoning is simple really. When you pass your pointer to a function it copies the …

You could simplify your program like below: [code] #include <stdio.h> #include <stdlib.h> int main(int argc, char**argv) { char num[10]; FILE *fd; if (!(fd = fopen("testdata", "r"))) { fputs("could not open file!\n", stderr); exit(EXIT_FAILURE); } while (fscanf(fd, "%s", num) != EOF) { fprintf(stdout, "num->%s\n", num); } fclose(fd); exit(EXIT_SUCCESS); } [/code] This …

You might to include just a bit more of the code...I have no idea what a obj is. Is it a variable, a reference to a variable, a pointer.... Your error. Did you try casting the void pointer to the appropriate type.

You have to, at least, save the original pointer value somewhere so that you can delete and free up the memory...otherwise you create a memory leak.

So where exactly is your 'if loop'? Which line?

Here's a more complete definition [url]http://msdn.microsoft.com/en-us/library/wt88dxx6%28VS.80%29.aspx[/url]

Well the default constructor set degree to zero....the first element of the array coefs. [code] Poly Poly:: operator+(const Poly& p) { Poly temp; for (int i=0; i<degree; i++){//look here...what's degree equal? temp.coefs[i] =coefs[i] + p.coefs[i]; } return temp; } [/code]

I really don't know why your using overloaded functions when you really should be using overloaded constructors like below: [code] #include<iostream> class math { public: math(double side1, double side2):area(side1 * side2) {} math(double rad):area(3.14 * rad * rad) {} double getarea() const {return area;} private: double area; }; int main() …

This #include <iostream.h> Should be #include <iostream> and cout should be std::cout

Try this to start out... [code] #include <string> using namespace std; class car { private: int yearModel; string make; int mpg; public: car(); }; car::car () { yearModel = 0;//zero is a good value to set numeric primary data types mpg = 0;//zero is a good value to set numeric …

That's because you need a separate thread of execution to execute the timers..I would investigate threads.

Try something like below [code] #include <stdio.h> #include <stdlib.h> #include <string.h> void mycall(char cmd[]) { char *pch = NULL; printf ("%s\n", cmd); /* correctly prints 'ls -l' */ printf ("Before call to strtok\n"); pch = strtok (cmd, " "); printf ("After call to strtok\n"); } int main() { char cmd[] …

So you want a function the behaves exactly like clrsrc but isn't clrsrc?

You should start my defining x as a string and then compare it to things likes "brown" Please note the double quotes not signal quotes. Or better yet you should create an enumeration. enum Colors {brown, red, yellow,...etc};

First you didn't allocate any memory for the str character pointer....

You have this atoi(argv[i]); Which doesn't save the value generated by the function atoi() Here's the definition of atoi int atoi(const char *nptr); Note it returns an integer and does not change the value of nptr in place.

I'm not really sure what you mean...Is it something like below? [code] #include <iostream> int main(int argc, char**argv) { unsigned int i = 0; unsigned int x = 1; int size = sizeof(unsigned int); size *= 8; std::cout<<"ans->"<<x<<std::endl; for (i = 0; i < size; ++i) std::cout<<"ans->"<<(x <<= 1)<<std::endl; return …

LNAME is a float....You probably want a string for LNAME.

Not absolutely sure what your trying to accomplish here. Is this what your looking for? [code] #include <iostream> class BaseClass { protected: double parameter; }; class DerivedClass : public BaseClass { }; class SecondDerivedClass : public BaseClass { }; class AnotherClass { public: void setParameterOfDerivedClass( BaseClass * baseClass, double parameterValue …
