Whats the error here?

int x;
puts("input value 1");
scanf("%d",&x);
int y;
puts("input value 2");
scanf("%d", &y);

int sum;
sum = x + y;

printf("the sum is %d\n" , sum); //here sum is %d because int sum; , which means the sum is a variable here and the value of variable is defined or mentioned as %d
}
