用递归的方式颠倒字符串

/* Example to reverse a sentence entered by user without using strings. */ #include <stdio.h>void Reverse();int main(){    printf("Enter a sentence: ");    Reverse();    return 0;}void Reverse(){    char c;    scanf("%c",&c);    if( c != '\n')    {        Reverse();        printf("%c",c);    }}

结果输出：

Enter a sentence: margorp emosewaawesome program
