What action does the following a default operator perform? int a, b, c; a = b + c;

The code defines 3 integers a, b and c, then defines a as the sum of b and c.

Explanation:

In the programming language C int data type is used to declare an integer variable, that is, it can store only both negative or positive integers. I will leave a complete example about it:

#include <conio.h>

#include <stdio.h>

int main()

{

   int a, b, c;

   printf( "\n   Introduce first integer (entero): " );

   scanf( "%d", &b );

   printf( "\n   Introduce second integer (entero): " );

   scanf( "%d", &c );

   a = b + c;

   printf( "\n   The sum is: %d", a );

   getch(); /* Pause */

   return 0;

}
