Thread: comparison problem

Hi, I am new to C++ so this may seem like a stupid problem, but it has me stumped.


What I'm supposed to do here, is compare the value in mysign to +. Add if it is +, subtract if it is -, and display error message if it is neither.
this is what I have so far:

Code:

#include <iostream>
using namespace std;

main()
{	

	int first, second, result=0; 
	char mysign;

	cout<<"Please input an integer. \n";
	cin>> first;

	cout<<"Please input an integer once again. \n";
	cin>> second;

	cout<<"Please input + or - \n";
	cin>> mysign;

    if (+ == mysign) ; {
		cout<< first+second;
		cin>> result;
	}
	else if(- == mysign) ; {
		cout<< first-second;
		cin>> result;
	}
	else ;{
		cout<< "Cannot perform an operation.\n";
	}

	cout<<"The variable stored in result is:" << result << endl;

	cin.get();
	return 0;
}

There are probably many things wrong here, please help me correct them. I'm lost.

Code:

#include <iostream>
using namespace std;

int main()
{	

	int first, second, result=0; 
	char mysign;

	cout<<"Please input an integer. \n";
	cin>> first;
	cin.ignore();

	cout<<"Please input an integer once again. \n";
	cin>> second;
	cin.ignore();

	cout<<"Please input + or - \n";
	cin>> mysign;
	cin.ignore();

    if (mysign=='+')  {
        result = first + second;
	}
    if(mysign=='-')  {
        result = first - second;
	}

	cout<<"The variable stored in result is: " << result << endl;

	cin.get();
	return 0;
}

Here, I cleaned up the code for you.

Thank you all very much.
