二级C程序修改（五）

测试描述:
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
给定程序中的函数乐趣MODI1。C
例如，当s="ABBCDE "和t="BDFG "时，U中的字符串为:" BBD "。
请更正fun函数中的错误，以便它能得到正确的结果。注意:不要
改变主函数，添加或删除行，或者改变程序的结构！
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
程序:
= = =包含
void fun (char *s，char *t，char *u)
{ int i，j，sl，TL；
sl = slen(s)；TL = slen(t)；
for(I = 0；I { for(j = 0；j if(s[I]= = t[j])break；
/**********找到了* * * * * * * * * * */
if(j > = TL)
* u = s[I]；
}
/* * * * * * * * * * * *找到了* * * * * * * * * */
* u = ' 0 '；
}

main()
{ char s[100]，t[100]，u[100]；
clrscr()；
printf(" \ n请输入歌曲:")；scanf("%s "，s)；
printf(" \ n请输入sing t:")；scanf("%s "，t)；
fun(s，t，u)；
printf("结果为:%s\n "，u)；
}
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
所需数据:[(j > = TL))
if(TL > j)
if(！(TL @ 2 001006
* u = ' \ 0 '；
* u = 0；
(* u)= ' \ 0 '；
(* u)= 0；
u[0]= ' \ 0 '；
u[0]= 0；
