I set them as
int sum1, sum2, sum3, sum4;
int subt1, subt2, subt3, subt4;
int multi1, multi2, multi3, multi4;
int modu1, modu2, modu3, modu4;
int divi1, divi2, divi3, divi4;
on the top.
I am trying to print the results. So sorry english isn't my first language :(
Now at the bottom, I am trying to print out my result but I am getting error.
