Create a 'STRING' class which overloads ‘ == ' operator to compare two STRING objects.

Create a 'STRING' class which overloads ‘ == ' operator to compare two STRING objects.

#include<iostream.h>

#include<conio.h>

#include<string.h>

class string

{

char *p;

int len;

public:

string()

{ }

string( char *s)

{

len=strlen(s);

p=new char[len+1];

strcpy(p,s);

}

friend int operator = =( string &s,string &t);

};

int operator = = ( string &s1,string &s2)

{

if(strcmp(s1.p,s2.p)= =0)

return(1);

else

return(0);

}

int main()

{

string s1,s2;

char str1[20],str2[20];

clrscr();

cout<<"\nEnter the first string : ";

cin>>str1;

cout<<"\nEnter the second string : ";

cin>>str2;

s1=str1;

s2=str2;

if(s1= =s2)

cout<<"\nStrings are equal";

else

cout<<"\nStrings are not equal";

getch();

return 0;

}

The output of the above program:

Enter the first string : cpc

Enter the second string : cs

Strings are not equal

Enter the first string : CPC

Enter the second string : CPC

Strings are equal

Thanks
