#include <stdio.h>
int main()
{
int x,y;
x = 10;
y = -3;
printf("x+y=%d\n", x+y );
printf("x-y=%d\n", x-y );
printf("x*y=%d\n", x*y );
printf("x/y=%d\n", x/y );
printf("x%%y=%d\n", x%y);
return 0;
}
#include <stdio.h>
int main()
{
int x = 5;
int y = 8;
//在这里合适的位置加上括号使z的值为4
int z = x*8/(y+2);
printf("z=%d\n", z);
return 0;
}
