Ok, in my C++ Console Project, I am prompting the user to make a choice of multiplication, addition, subtraction, or division, and then enter two numbers to perform the selected operation. But I am having some syntax errors I am not sure how to fix. Here is my code:

[code=cpp]
#include "stdafx.h"
#include <iostream>
#include <string>
#include <time.h>
#include <stdio.h>

using namespace std;

void Wait(int seconds)
{
clock_t endwait;
endwait = clock () + seconds * CLK_TCK ;
while (clock() < endwait) {}
}

int main( void )

{
//variables
int number1;
int number2;
int answer;
char choice;
char keepplaying = "y";
//code
while(keepplaying == "y")
{
cout << "Enter your choice of math (+ , - , /, x): ";
cin >> choice;
if(choice = "+")
{
cout << "Enter two numbers to add together:" << endl;
cin >> number1;
cout << "+" << endl;
cin >> number2;
cout << endl;
answer = number1 + number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else if(choice = "-")
{
cout << "Enter two numbers to subtract:" << endl;
cin >> number1;
cout << "-" << endl;
cin >> number2;
cout << endl;
answer = number1 - number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else if(choice = "/")
{
cout << "Enter two numbers to divide:" << endl;
cin >> number1;
cout << "/" << endl;
cin >> number2;
cout << endl;
answer = number1 / number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else if(choice = "x")
{
cout << "Enter two numbers to add together:" << endl;
cin >> number1;
cout << "x" << endl;
cin >> number2;
cout << endl;
answer = number1 * number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else
{
cout << "That is not a valid option." << endl << endl << endl << endl;
}
cout << "Play again? (Y/N)" ;
cin >> keepplaying;
}

}
[/code]

And here is the build log.






I am using Windows with Microsoft Visual C++ 2008 Express Edition. This is a console project.

I am running MinGW IDE, but I make the following changes to the code and it work. hehe.

I compiled and following changes in visual studion 6.0, Please check.


#include "stdafx.h"
#include <iostream>
#include <string>
#include <time.h>
#include <stdio.h>

using namespace std;

void Wait(int seconds)
{
clock_t endwait;
endwait = clock () + seconds * CLK_TCK ;
while (clock() < endwait) {}
}

int main( void )

{
//variables
int number1;
int number2;
int answer;
char choice;
char keepplaying = 'y';
//code
while(keepplaying == 'y')
{
cout << "Enter your choice of math (+ , - , /, x): ";
cin >> choice;
if(choice = '+')
{
cout << "Enter two numbers to add together:" << endl;
cin >> number1;
cout << "+" << endl;
cin >> number2;
cout << endl;
answer = number1 + number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else if(choice = '-')
{
cout << "Enter two numbers to subtract:" << endl;
cin >> number1;
cout << "-" << endl;
cin >> number2;
cout << endl;
answer = number1 - number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else if(choice = '/')
{
cout << "Enter two numbers to divide:" << endl;
cin >> number1;
cout << "/" << endl;
cin >> number2;
cout << endl;
answer = number1 / number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else if(choice = 'x')
{
cout << "Enter two numbers to add together:" << endl;
cin >> number1;
cout << "x" << endl;
cin >> number2;
cout << endl;
answer = number1 * number2;
cout << endl << "Calculating...";
Wait( 5 );
cout << " ... Done Calculating! Your answer is... " << answer << endl << endl;
system("PAUSE");
}
else
{
cout << "That is not a valid option." << endl << endl << endl << endl;
}
cout << "Play again? (Y/N)" ;
cin >> keepplaying;
}

}

@dgirdhar: Please put in a [c0de] [/c0de] tag, but spell code correctly.

@cheesebeefy:this probably will not solve your problem, but try using a switch statement, as follows:



EDIT: char 'keepplaying' should be char keepplaying == 'y', as opposed to "y". Note the diff.
Same for everywhere else you used double quotes to declare/compare a char type variable.

Thank you everyone! That fixed it. And I'll try out that switch statement QWERTY. :)
