1.!strcmp(“alush”, “flush”)：比较两个字符串，相同为1，不同为0

举例：

#include <stdio.h>
int main(void) { 
{ 
    printf("Hello World %d\n",!strcmp("alush", "flush")); 
    printf("Hello World %d\n\n",strcmp("alush", "flush"));

    printf("Hello World %d\n",!strcmp("flush", "flush")); 
    printf("Hello World %d\n\n",strcmp("flush", "flush"));

    printf("Hello World %d\n",!strcmp("glush", "flush")); 
    printf("Hello World %d\n",strcmp("glush", "flush")); 

return 0;
}

输出：

Hello World 0
Hello World -1

Hello World 1
Hello World 0

Hello World 0
Hello World 1

0
