Also notice the error : "application wrote to memory after end of heap buffer"
It says that you wrote into memory where you were not supposed to. If thats the case, then look in your code where you write into heap, and most likely, thats where you will find your problem.
"So while cout.width() exists, I do not think there is much reason to use it unless you really hate including <iomanip> for the parameterized manipulators."
Its just easier for me to use cout.width, instead of including iomanip, and using setw().
enum Direction {LEFT,RIGHT,UP,DOWN};
int getRandDir() { return rand()%4; }
int main()
{
Direction curr_direction = getRandDir()
switch(curr_direction)
{
case LEFT : if(canMoveLeft) then moveLeft; break;
case RIGHT : if(canMoveRight) then moveRight; break;
// same for UP and DOWN
}
}
Of course you need someType of algorithm to get Robot to that destination
Something like this ? Don't know why you would wan't to do this for.
for(int i = 0 ; i < 100; i++)
{
cout<<"Enter a seed value : ";
int seed = 0;
cin >> seed;
while(seed < 0) { cout<<"\nEnter non negative number : "; cin >> seed; }
cout<<"\nYour random number is : "<<rand()<<endl;
}
//open a file for for reading and writin
ofstream oFile("outputFile.txt");
ifstream iFile("inputFile.txt");
char c;
std::string str;
while(iFile.get(c)) { str +=c; } //read in data
//now write into the output file
5 * 5 = i
---------------
5 * 5 = 0 /// 25 = 0 // = false
5 * 5 = 1;// 25 = 1 // false
5 * 5 = 2;// 25 = 2 // false
5 * 5 = 3//25 = 3 //false
// so on until i = 25, then it would be true, but has no effect on the
loop
Did that make sense? Obviously m*m =i , is not what you want to do. I think you are looking for is what wildgoose posted.
const unsigned int MAX = 25; BaseClass * pBC[MAX];
Make sure BaseClass has some virtual function if needed.
Now you can static bind or dynamic bind.
Static Bind :
pBC[0] = new BaseClass
pBC[1] = new InherietFromBaseClass
//and so on
Dynamic binding
cout<<"1 for baseclass, 2 for InherietFromBaseClass, //and so on";
int opt = 0;
cin >> opt;
if(opt == 1) pBC[0] = new BaseClass
//and so on
This might be of help. Much easier way of reversing a string.
//note using mathematical notation its [strt,end] and not [strt,end).
//strt is included and end is included as well.
void reverseRecursivly(string& str,int strt, int end)
{
if(strt >= end || !str[0]) return;
std::swap(str[strt],str[end]);
reverseRecursivly(str,strt+1,end-1);
}
To convert decimal value to percentage you divide a value by its max attainable value. For interest if user inputs 6 percent, the max percent attainable is 100, so we divide 6 by 100 to get the percentage. Also
if (interest <= 0) {
cout << "Please enter a valid Interest Rate";
cin >> interest;
}
You might want to make that a while loop, so until the user enters a correct value, he gets prompted.
"Also, I've been trying to research how to hop out of a function when a condition is met"
if(condition is met) return false; //assuming function is bool returned typed
int main()
{
while(Alive)
{
if( checkConditionIsMet() == false) return out of this function.
//some stuff
}
}
I mean no matter how bad your teacher is, he/she wouldn't be hired if they weren't capable of give AT LEAST the basic knowledge of programming and where to start.
True, but that doesn't necessarily mean that he has good programming habits.
