Description

Swap Strings Physically, swap the strings in a 2-dimensional array of characters

Demo Code

#include <stdio.h>

int main()//from  w  w  w.ja  v  a  2 s .  co  m
{
      char temp;
      char friends [5][10] = {
                            "abc",
                            "def test",
                            "1234",
                            "12345",
                            "99"
                          };
    
      printf("Strings before swapping:\n");
      for(int i = 0; i < 5; i++)
         printf("Friend no. %d : %s\n", i+1, friends[i]);
    
      for(int i = 0; i < 10; i++) {
          temp = friends[0][i];
          friends[0][i] = friends[1][i];
          friends[1][i] = temp;
      }
      printf("\nStrings after swapping:\n");
      for(int i = 0; i < 5; i++)
         printf("Friend no. %d : %s\n", i+1, friends[i]);
    
      return(0);
