程序在C中交换字符串（Program to swap strings in C）

实现 (Implementation)

现在，我们将看到该计划的实际执行情况 -

#include <stdio.h>
int main() {
   char s1[] = "TajMahal";     
   char s2[] = "Dazzling";     
   char ch;
   int index = 0;
   //Character by Character approach
   printf("Before Swapping - \n");
   printf("Value of s1 - %s \n", s1);
   printf("Value of s2 - %s \n", s2);
   while(s1[index] != '\0') {
      ch = s1[index];
      s1[index] = s2[index];
      s2[index] = ch;
      index++;
   }
   printf("After Swapping - \n");
   printf("Value of s1 - %s \n", s1);
   printf("Value of s2 - %s \n", s2);
   return 0;
}

输出 (Output)

该计划的输出应为 -

Before Swapping -
Value of s1 - TajMahal
Value of s2 - Dazzling
After Swapping -
Value of s1 - Dazzling
Value of s2 - TajMahal
