字符串练习——输入关键字找歌曲

#include<stdio.h>
#include<string.h>  //要用strstr()函数来查找字符串 
char tracks[][80] = {  //歌曲清单 
    "I left my heart in Harvard Med School",
    "Newark,Newark - a wonderful town",
    "Dancing with a Dork",
    "From here to maternity",
    "The girl from Iwo Jima",
}; 

void find_track(char search_for[])
{
    int i;
    for(i=0;i<5;i++){
        if(strstr(tracks[i],search_for))  //显示所有匹配的歌曲 
        printf("Track %i:'%s'\n",i,tracks[i]);
    }
}

int main()
{
    char search_for[80];
    printf("Search for:");  //输入查找的关键字 
    fgets(search_for,80,stdin);
    search_for[strlen(search_for)-1]='\0';
    find_track(search_for);  //显示匹配的歌曲 
    return 0;
}
