A Pascal program is written to compare two integers entered from the keyboard and output the larger one, as long as neither number is zero or negative. The program prompts the user to enter two numbers, reads them in as variables a and b, checks if either is less than or equal to 0 to detect negatives, and if not negative compares the numbers and writes the larger one to the output.

1. Write a PASCAL program to compare two integers entered from the keyboard and output the
larger one, the number should neither be a zero nor a negative.
Solution
Pascal Code:
program Larger;
var
a: Integer;
b: Integer;
begin
writeln('Enter First number');
readln(a);
writeln('Enter Second number');
readln(b);
if a<=0 then
writeln('Negative number detected!');
else if b<=0 then
writeln('Negative number detected!');
else
if a>b then
writeln(a);
else
writeln(b);
end.
