Program to print the mismatched characters


Write a program to print the mismatched characters from two array. Output must be like the one given below.


  • The logic is simple, compare each character of the same index.
  • If characters are mismatched then print both the characters.
  • If characters are same, then increment the index position of both arrays.
  • After comparing each index, if anyone array has more characters than another, print the remaining characters.


#include <iostream>
using namespace std;
int main()
    char a[]={'a','b','c','d','e'};
    char b[] = { 'a','b','b','d','f','g'};
    int i=0,j=0;

        if(b[j]=='\0')          //IF REACHED LAST INDEX IN B ARRAY
            i++;                //INCREMENT INDEX OF BOTH ARRAY
        } else
            cout<<a[i++]<<" "<< b[j++]<<" ";
    while(a[i]!='\0')           //REMAINING ITEMS OF A
        cout<<a[i++]<<" ";
    while(b[j]!='\0')           //REMAINING ITEMS OF B
        cout<<b[j++]<<" ";
    return 0;
