%d/n,的后面應該加上什么？
hello.c
#include <stdio.h>
int main()
{
??? int x,y;
??? x = 10;
??? y = -3;
??? printf("x+y=%d\n",???? );?
??? printf("x-y=%d\n",???? );
??? printf("x*y=%d\n",???? );
??? printf("x/y=%d\n",???? );
??? printf("x%y=%d\n",???? );?
??? return 0;???
}
本課程編程練習請

hello.c
#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;????
}//上面的雙引號里的%d意思是輸出結果的類型屬于帶符號十進制整數，實際輸出的值在逗號后面。

加上%d所代表的10進制變量

#include <stdio.h>
#include <stdlib.h>
int main()
{
int x,y,t;
? ? x = 10;
? ? y = -3;
? ? t=x+y;
? ? printf("x+y=%d\n",t);
? ? t=x-y; ?
? ? printf("x-y=%d\n",t);
t=x*y;
? ? printf("x*y=%d\n",t);
t=x/y;
? ? printf("x/y=%d\n",t);
t=x%y;
? ? printf("x%y=%d\n",t);?
system("pause");
return 0;
}
//結果//x+y=7
//x-y=13
//x*y=-30
//x/y=-3
//xy=1
//請按任意鍵繼續. . .
