c语言中条件运算符 + 语句

001、

[root@localhost test]# ls
test.c
[root@localhost test]# cat test.c
#include <stdio.h>

int main(void)

{
        int n1,n2;

        puts("please input two integers.");
        printf("n1 = "); scanf("%d", &n1);
        printf("n2 = "); scanf("%d", &n2);

        (n1 == n2) ? puts("equal"):puts("no equal");    //条件运算符后直接加执行语句

        return 0;
}
[root@localhost test]# gcc test.c -o kkk
[root@localhost test]# ls
kkk  test.c
[root@localhost test]# ./kkk
please input two integers.
n1 = 8
n2 = 3
no equal
[root@localhost test]# ./kkk
