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.
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";
}

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
end
