Most used string functions in C++ with an example program !

 #include <iostream>

#include <cstring>

using namespace std;

int main (){

   char s1[80],s2[80];

   gets(s1);

   gets(s2);

   cout << strlen(s1) << " " << strlen(s2)<< endl;

   if(strcmp(s1,s2)){

    cout << "The Strings are equal"<<endl;

   }

   strcat(s1,s2);

   cout << s1 << endl;

   strcpy(s1,"This is a test.\n");

   cout << endl;

   cout << s1;

   cout << endl;

   if(strchr("hello",'e')){

    cout << "e is in hello"<<endl;
