Thread: Compile Errors in my Code. Can anyone help?

Code:

#include <stdio.h>
 
void getinput (int* pnum1, int* pnum2);
int calc (int num1, int num2);
void calcintops (int num1, int num2);
void doubleops (int num1, int num2);
int division (int num1, int num2);
// This doesn't work. Each argument must have a type.
void display (int num1, int num2, sum, quotient, remainder, half_num1,
half_num2, fraction, division);
     
int main (void)
{
     // All unreferenced variables (ie not used anywhere). I assume you're going to use them when writing some more code later?
     int num1,num2;
     int sum;
     double half_num1, half_num2;
     int quotient;
     int remainder;

     return 0;
}

     printf("\nPlease enter two integers, num1 and num2: ");
     // This doesn't work. Arguments passed to scanf must be outsides the quotes ("").
     scanf("&#37;d%d, pnum1, pnum2");
}

}

}

     // These are all wrong. I suggest you read up on printf again.
   printf("\n%20s%20d", "The value of num1 is %d", num1);
   printf("\n%20s%20d", "The value of num2 is %d", num2);
   printf("\n%20s%20d", "The sum is %d + %d", num1, num2);
   printf("\n%20s%20f", "The half value is %d / 2", num1);
   printf("\n%20s%20f", "The half value is 2 * %d / 2", num2);
