~~ 我编的这个程序主要是是最后错了错误`~`
`我希望程序要做的事情完成后` ~~出现一个选择``提示我们是不是~再运行一次程序`~再用一次程序``
我把提示程序提取出来了`~:

void ifw(void); /*当输入错误时`提示重新输入*/
void welcome(void); /*退出程序时的一段输出*/
char gorq(void); /*提示用户是否还想继续运行程序*/

begain:b=gorq(); /*调用提示*/
/*如果想再运行就输入Y(y),想退出就输入N(n)*/

程序出错在与`~除了输入N或n没错以外`~
输入其他非N(n)或非Y(y)~~时~~回出现 2 次输入错误提示`~
而输入Y或y时~~程序回从头再来一次`~但是回多出一个 输入错误提示(当程序第一次执行完后``走到这里也会自然的回多
出 输入错误提示)
很麻烦的是我用了GOTO`~~
因为想不到用别的什么方法了``
请各位朋友指出错误`~给点提示``多谢多谢`
能给经验的~~多多传授~`THANKS~~`
如果需要原来的整段代码``
