C++ এ STL অ্যারেতে রিলেশনাল অপারেটর

দ্রষ্টব্য:L.H.S-এ উভয় STL অ্যারে এবং R.H.S. .

সময়ের জটিলতা তুলনা রৈখিক সময় এবং অ্যারের আকারের উপর নির্ভর করে। O(n)

শর্ত ধরে রাখলে রিটার্ন মান সত্য বা অন্যথায় মিথ্যা।

উদাহরণ

#include <iostream>
#include <stdio.h>
#include <array>
using namespace std;

   array<int, 5> marks3 = { 10,20,30,40,50 };
   //a>=b is equivalent to !(a<b) as shown
   if (marks1 >= marks2){
       cout << "Marks1 is greater than equal to Marks2\n";
   }
   else{
      cout << "Marks1 is neither greater nor equal to Marks2\n";
