Get two integers from the user, and then output if the first one is less, equal or greater than the other. Test the condition for each case separately, so that all three comparison operators are used in the code.
Ada
with Ada.Text_IO; use Ada.Text_IO; with Ada.Integer_Text_IO; use Ada.Integer_Text_Io; procedure Compare_Ints is A, B : Integer; begin Get(Item => A); Get(Item => B); -- Test for equality if A = B then Put_Line("A equals B"); end if; -- Test For Less Than if A < B then Put_Line("A is less than B"); end if; -- Test For Greater Than if A > B then Put_Line("A is greater than B"); end if; end Compare_Ints;
C++
#include <iostream> #include <istream> #include <ostream> int main() { int a, b; std::cin >> a >> b; // test for less-than if (a < b) std::cout << a << " is less than " << b << "\n"; // test for equality if (a == b) std::cout << a << " is equal to " << b << "\n"; // test for greater-than if (a > b) std::cout << a << " is greater than " << b << "\n"; }
Fortran
program compare integer a, b read(*,*) a, b c c test for less-than if (a .lt. b) then write(*, *) a, ' is less than ', b end if c c test for equality if (a .eq. b) then write(*, *) a, ' is equal to ', b end if c c test for greater-than if (a .gt. b) then write(*, *) a, ' is greater than ', b end if c end
