Question

1.Question

For the following code:

int a = -1;

int b = a * 5;

printf("a is %d, and b is %d.\n", a, b);

What is the output?

2.Question

int x = -1;

int y = 3;

x= x + Y;

printf("x - y is %d.\n", x - y);

Answer 1

#include <stdio.h>

int main()

{

int a = -1;

int b = a * 5;

printf("a is %d, and b is %d.\n", a, b); // a is -1 and b is -5

int x = -1;

int y = 3;

x= x + y; // x=2 <--- COMPILE ERROR HERE... you have capital Y; we fixed it

printf("x - y is %d.\n", x - y); // x - y is -1 because 2-3 = -1

}
