換一種形式

int x,y;
int a,b,c,d,e;
x = 10;
y = -3;
a=x+y;
b=x-y;
c=x*y;
d=x/y;
e=x%y;
printf("x+y=%d\n", a);?
printf("x-y=%d\n", b);
printf("x*y=%d\n", c);
printf("x/y=%d\n", d);
printf("x%%y=%d\n", e);?
return 0;?
再定義五個變量不也可以？

#include<stdio.h>???//你開頭的這幾行沒寫，沒有定義這些變量
int?main()
{
????int?x,y;
????int?a,b,c,d,e;
????x?=?10;
????y?=?-3;
????a=x+y;
????b=x-y;
????c=x*y;
????d=x/y;
????e=x%y;
????printf("x+y=%d\n",?a);
?????printf("x-y=%d\n",?b);
?????printf("x*y=%d\n",?c);
?????printf("x/y=%d\n",?d);
?????printf("x%%y=%d\n",?e);?
?????return?0;?
