CODE EXAMPLE FOR CPP

compare function in c++

// CPP code for demonstrating
// string::compare (const string& str) const
 
#include<iostream>
using namespace std;
 
void compareOperation(string s1, string s2)
{
    // returns a value < 0 (s1 is smaller than s2)
    if((s1.compare(s2)) < 0)
        cout << s1 << " is smaller than " << s2 << endl;
 
    // returns 0(s1, is being compared to itself)
    if((s1.compare(s1)) == 0)
        cout << s1 << " is equal to " << s1 << endl;
    else
        cout << "Strings didn't match ";
     
}
 
// Driver Code
int main()
{
    string s1("Geeks");
    string s2("forGeeks");
    compareOperation(s1, s2);
     
    return 0;
