The way if works in C++ is that we put a condition in bracket if that is satisfied the code in if executes otherwise if else is there its code executes.If there is no else present then nothing happens.Relational operators in C++ are >(greater than),<(less than),>=(greater than or equal to),<=(less than or equal to),==(equal to),!=(not equal to).
