Question

Write a function called swapElements to swap two elements in a character array. This function takes two parameters, a character array and input file. The function should read two numbers from a file and it swap the elements stored in the indices read. please code in c++

Answer 1

#include<bits/stdc++.h>
using namespace std;

void swapElements(char aray[],ifstream &file)
{

   int count= 0;
   int val;
   int index1,index2; //declaring index variable to store index from file
   int arr[30];

   while (count < arr[2] && file >> val)
        arr[count++] = val;         //storing index first in array

   for (int i = 0; i < count; i++) {
        index1=arr[0];                  //assigning index from array to index variables
        index2=arr[1];
   }
   char temp;

   temp=aray[index1];               //swapping character array element with index1 and index2
   aray[index1]=aray[index2];
   aray[index2]=temp;
}

int main()
{

ifstream file("C:\\Users\\hp\\Desktop\\file.txt"); //importing file using ifstream object

    char aray[6]={'s','w','g','j','q','n'};

    swapElements(aray,file); //calling function by passing array and file

     for(int i=0;i<6;i++)
    {
        cout<<aray[i]<<" ";
    }

   file.close(); //closing file
}
