I can't seem to figure out whats wrong with this code
. it wont pause after you give you answer to last question....
P.S. It's a nooby mistake I bet lol.
Code: Select all
#include <iostream>
#include <string>
using namespace std;
int main(int argc, char *argv[])
{
int x = 0;
int c = x + 5;
string name;
int answer1;
cout << "what would you like your name to be?" << endl;
cout << ">"; cin >> name;
cout << "hello nice to meet you " << name << endl;
cin.get();
cout << "what is your favorite number " << name << endl;
cout << ">"; cin >> x;
cout << "Your favorite number is " << x << endl;
cin.get();
cout << "what is your favorite number +5?" << endl;
cout << ">"; cin >> c;
if( c != x+5 )
cout << "Wrong@@@@" << endl;
else if( c = x+5 )
cout << "Correct!!" << endl;
cin.get();
}
Try that.

if I have a bug like that won't it cause a memory leak or something?
and that just says c is equal to x+5 not asking the question if it actually is equal to x+5

The reason that piece of code is a bug is the '=' operator is actually the assignment operator. The '==' operator is used to test for equality. It's a very common error that the compiler doesn't catch, unless you have the warning level set to the highest.

No, memory leaks only occur when you dynamically allocate memory. You wont encounter them for a fair while until you are past understanding the basics.
