下列给定程序中，函数fun()的功能是：删除字符串s中所有空白字符(包括Tab字符、回车符及换行符)。输入字符串时用’#’结束输入。 请改正程序中的错误，使它能得出正确的结果。 注意：不要改动main函数，不得增行或删行，也不得更改程序的结构． 试题程序： #include ＜string.h＞ #include ＜stdio.h＞ #include ＜ctype.h＞ fun(char *p) { int !i, t; char c[80]; for(i=0,t=0;p[i];i++)if(!isspace(*(p+i))) c[t++]=p[i]; /**********************************/ c[t]=’\0’; strcpy(p,c); } main() {char c,s[80]; int i=0; printf("Input a string: "); c=getchar(); while(c!=’#’) ( s[i]=c;i++;c=getchar();} s[i]="\0"; fun(s); puts(s); {
