Checking two Strings equal or not and Concatenate two strings using Class in C++

In this C++ program we will Create a class ‘STRING’ which has one data member ‘str’. The class can perform concatenation of two string by ‘+’ operator overloading and check given two string are equal or not by ‘==’ operator overloading. Strings will be given by the user.

input:

Two Strings.

output:

Either the strings will be equal to each other or not and after that they will be concatenated.

CODE---->

#include<iostream>
#include<string.h>
using namespace std;
class STRING
{
 private:
  char str[100];
 public:
  void getString()
  {
   gets(str);
  }
  void display()
  {
   puts(str);
  }
  STRING operator+(STRING X)
  {
   STRING s;
   strcpy(s.str,str);
   strcat(s.str,X.str);
   return(s);
  }
  int operator==(STRING X)
  {
   if(strcmp(str,X.str)==0)
    return 1;
   else
    return 0;
  }
};
int main()
{
 STRING s1,s2,s3;
 cout<<"Enter 1st String: ";
 s1.getString();
 cout<<"Enter 2nd String: ";
 s2.getString();
 cout<<"\n-----------------------\n";
 cout<<"1st String is: ";
 s1.display();
 cout<<"2nd String is: ";
 s2.display();
 cout<<"\n-----------OUTPUT--------------\n";
 if(s1==s2)
  cout<<"**String are equal**";
 else
  cout<<"**String are not equal**";
 cout<<"\nConcatenation of given two string is: ";
 s3=s1+s2;
 s3.display();
}
