这里我们定义了一个函数reverse_string,这个函数递归地调用它自己。
#include <stdio.h>#include <string.h>void reverse_string(char*, int, int);int main(){//This array would hold the string upto 150 charchar string_array[150];printf("Enter any string:");scanf("%s", &string_array);//Calling our user defined functionreverse_string(string_array, 0, strlen(string_array)-1);printf("\nReversed String is: %s",string_array);return 0;}void reverse_string(char *x, int start, int end){char ch;if (start >= end)return;ch = *(x+start);*(x+start) = *(x+end);*(x+end) = ch;//Function calling itself: Recursionreverse_string(x, ++start, --end);}
输出:
Enter any string: chaitanyaReversed String is: aynatiahc
