    Super Quick Help

    Code:
    #include <iostream>using namespace std;
    
    
    int main()
    {
    	int a;
    	int b; 
    	int c;
    
    
    	cout << "Enter a number:" << endl;
    	cin >> a;
    	cout << "Enter a number:" << endl;
    	cin >> b;
    
    
    	c = a + b;
    
    
    	cout << "The sum of those numbers is:" << endl;
    	cout << c;
    	cin.get();
    }
    I wrote this, tried to run it and it just closes the console as soon as the program is finished. What did I do wrong?

    Run your program in a separate command prompt window.

    If you really want to do it this way, then insert a cin.ignore() before the cin.get() to ignore the newline character left in the input buffer from cin >> b;

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    I was curious, your compiler does not complain that you omit
    Code:
    return 0;
    in
    Code:
    main();

    No, it is not required by the standard.
    If omitted, the compiler will add an implicit return 0.
