题目内容

请补充main函数，该函数的功能是：把字符串str中的字符向前移动一位，原来的第一个字符移动到字符串尾，结果仍然保存在原字符串中。例如，输入“how do you do”，则结果输出“ow do you doh”。注意：部分源程序给出如下。请勿改动主函数main和其他函数中的任何内容，仅在 main函数的横线上填入所编写的若干表达式或语句。试题程序： #include ＜stdio. h＞ #define N 80 main() char str[N], ch; int i; clrscr (); printf("\n Input a string:In"); gets (str); printf("\n* original string In"); puts (str); ch=str [0]; for (i=0; 【1】 ; i++) str [i]=str [i+1]; 【2】 ; printf("\n new string *\n"); puts (str);
