Hey I started using this site to learn C yesterday, and I got to the chapter on functions and decided to try and make a little program to do simple calculations.

This is the what I've written so far;

Code:

#include <stdio.h>
int calc ( int x, int y );
int main()
{
int x;
char f;
int y;
printf( "Please input a number: " );
scanf( "%d", &x );
printf("Please choose a function(add, subtract, divide, or multiply):");
scanf("%c", f );
printf( "Please input a second number: " );
scanf( "%d", &y );
if (f == *);
{
printf( "The product of your two numbers is %d\n", mult( x, y ) );
}
else if (f == +);
{
printf( "The product of your two numbers is %d\n", add( x, y ) );
}
else if (f == /);
{
printf( "The product of your two numbers is %d\n", divide( x, y ) );
}
else (f == -);
{
printf( "The product of your two numbers is %d\n", subtract( x, y ) );
}
getchar();
}
int mult (int x, int y)
{
return x * y;
}
int add (int x, int y)
{
return x + y;
}
int subtract (int x, int y)
{
return x - y;
}
int divide (int x, int y)
{
return x / y;
}

However I can't seem to make it work, I get an error on the lines with the if statements saying; "syntax error before ')' token.

Can anyone help? Thanks
