Question

Create a C++ program to compare the length of two strings.

Answer 1

#include <iostream>#include <string>using namespace std;
int main()
{
     string s1, s2;
 
    cout<< "string1: "; cin>>s1;
    cout<< "string2: " ; cin>>s2;

    if ( s1.size()==s2.size() )
           cout<< "Strings:" + s1 + ":" + s2 + "are of same length";
    else
          cout << "Strings:" + s1 + ":" + s2 + " are NOT of same length" ;
 
    //  if you want to compare the two strings then:
    if (s1.compare(s2))
           cout<< "Strings:" + s1 + ":" + s2 + "are NOT same";
    else
            cout << "Strings:"  + s1 + ":" + s2 + "are Same" ;

    return 0;
}

Answer 2

#include <iostream>#include <string>using namespace std;
int main() 
{
     string s1, s2;
 
    cout<< "string1: "; cin>>s1;
    cout<< "string2: " ; cin>>s2; 

    if ( s1.size()==s2.size() )
           cout<< "Strings:" + s1 + ":" + s2 + "are of same length";
    else
          cout << "Strings:" + s1 + ":" + s2 + " are NOT of same length" ;
  
    //  if you want to compare the two strings then:
    if (s1.compare(s2))
           cout<< "Strings:" + s1 + ":" + s2 + "are NOT same";
    else
            cout << "Strings:"  + s1 + ":" + s2 + "are Same" ;

    return 0;
