1 回答为什么printf(x%%y=%d\n,x%y)需要两个%？

1 回答 printf("x%%y=%d\n",x%y );与 printf("x%y=%d\n",x%y );

2 回答#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;

2 回答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;

1 回答这个题我不理解，为什么"x+y=%d\n"和x+y 都存在？printf("x+y=%d\n",x+y )
