WebYou can use a comparison operator, such as the greater than(>) operator, to find out if an expression (or variable) is true or false: Example int x = 10; int y = 9; cout << (x > y); // returns 1 (true), because 10 is higher than 9 Try it Yourself » Or even easier: Example cout << (10 > 9); // returns 1 (true), because 10 is higher than 9 WebBasic Arithmetic Requirements. These requirements are common to all of the functions in this library.
