#include<stdio.h>
#include<stdlib.h>
#include<string.h>
//head frist c page 94
char tracks [][80] = {
		"给我一首歌的时间",
		"七里香",
		"威廉古堡",
		"简单爱",
		"东风破",
		"叶惠美",
};
void find_track(char search_for[]) {
	int i;
	for (i = 0; i < 6; i++) {
		if (strstr(tracks[i], search_for)) {
			printf("find track %i:%s\n", i,tracks[i]);
		}else{
			// printf("your search is %s,not in %s\n",search_for,tracks[i]);
		}	
	}
}
int main()
{
	char search_for[80];
	printf("search for :");
	fgets(search_for, 80, stdin);
	//由于fgets接收有换行符号+\0，所以把换行符换成结束符
	search_for[strlen(search_for)-1]='\0';
	find_track(search_for);
	return 0;	
}

结果：

search for :爱
find track 3:简单爱
