addition problem

Jake2k · 10-12-2002

I'm just learning C and I have this simple code that is suppose to find the sum of two integers.

Code:

#include <stdio.h>
#include <conio.h>

void main()
{
   int integer1, integer2, sum;  
   
   printf("Enter the first integer\n");
   scanf("%d", &integer1);
   printf("Enter second integer\n");
   scanf("%d", &integer1);
   sum = integer1 + integer2;
   printf("Sum is %d\n", sum);
         
   getch();
    
}

Whenever I add it into the Dev C++ compiler, the output looks something like this...

Enter the first integer
5
Enter second integer
5
Sum is 7601673

Can someone please tell me what I'm not doing to get the answer to be 10? Thanks.

try passing the reference instead of the variable itslef.

sum = &integer1 + &integer2 ;

That didn't work. It gave me the error message "invalid operands `int *' and `int *' to binary `operator +' ".

Do you think it could be the compiler settings? This code should work without problems.

You could try something like

Code:

#include <stdio.h>

int main(void) 
{
   
	int num1, num2;
	
	printf("Enter num1: ");
	scanf("%d", &num1);
	
	printf("Enter num2: ");
	scanf("%d", &num2); 
	
	printf("\n%d + %d = %d\n", num1, num2, (num1+num2));
	
	

return 0;
}

Or you might wanna set sum = 0 before using it since it might contain a garbage value.

err... no, don't do that.

The problem is actually a simple typo. You asked for two values from the user, but stored both in the same variable. Look at the 2 scanf() calls, both have integer1 in them.

Please use code tags when posting code too. See my signature for further help (or just ask me).

Hey, Hammer, thanks. I don't know how or why I did that.
