Four integers from the keyboard input, and calculate the square, according to the following format output (if the input is 2,3,4,5): (2 +3 +4 +5) * (2 +3 +4 +5 ) = 196
#include <stdio.h>
#include <math.h>
void main()
int x1,x2,x3,x4,y;

printf("please input four integers:");
printf("(%d+%d+%d+%d)*(%d+%d+%d+%d)=%d\n",x1,x2, x3,x4,x1,x2,x3,x4,y);
I am a beginner in C, the above is compiled, no errors, no warning, you can run, but out of the result is wrong. Which experts to help look, thank you
