There are following relational operators supported by C++ languageAssume variable A holds 10 and variable B holds 20 then:#include <iostream>using namespace std;main(){ int a = 21; int b = 10; int c ; if( a == b ) { cout << "Line 1 - a is equal to b" << endl ; } else { cout << "Line 1 - a is not equal to b" << endl ; } if ( a < b ) { cout << "Line 2 - a is less than b" << endl ; } else { cout << "Line 2 - a is not less than b" << endl ; } if ( a > b ) { cout << "Line 3 - a is greater than b" << endl ; } else { cout << "Line 3 - a is not greater than b" << endl ; } /* Let's change the values of a and b */ a = 5; b = 20; if ( a <= b ) { cout << "Line 4 - a is either less than \ or euqal to b" << endl ; } if ( b >= a ) { cout << "Line 5 - b is either greater than \ or equal to b" << endl ; } return 0;}When the above code is compiled and executed, it produces following result:Line 1 - a is not equal to bLine 2 - a is not less than bLine 3 - a is greater than bLine 4 - a is either less than or euqal to bLine 5 - b is either greater than or equal to bOperator Description Example== Checks if the value of two operands is equal or not, if yes then condition becomes true. (A ==) is nottrue.!= Checks if the value of two operands is equal or not, if values are not equal then condition becomes true. (A != B) istrue. > Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. (A > B) is not true. < Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. (A < B) is true. >= Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true. (A >= B) not true.<= Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. (A <= B) is true. C++
