# comparison in pascal

In Pascal, you can perform comparisons using various comparison operators. These operators include:

- "=": This operator checks if two values are equal.
- "<>": This operator checks if two values are not equal.
- "<": This operator checks if the left operand is less than the right operand.
- ">": This operator checks if the left operand is greater than the right operand.
- "<=": This operator checks if the left operand is less than or equal to the right operand.
- ">=": This operator checks if the left operand is greater than or equal to the right operand.

Here is an example that demonstrates the usage of comparison operators in Pascal:

```
program ComparisonExample;
var
a, b: integer;
begin
a := 5;
b := 10;
if a = b then
writeln('a is equal to b')
else if a <> b then
writeln('a is not equal to b');
if a < b then
writeln('a is less than b');
if a > b then
writeln('a is greater than b');
if a <= b then
writeln('a is less than or equal to b');
if a >= b then
writeln('a is greater than or equal to b');
end.
```

This code snippet assigns the values 5 and 10 to variables `a`

and `b`

, respectively. It then uses the comparison operators to compare the values of `a`

and `b`

and prints the corresponding messages based on the comparison results.

Note that Pascal is a case-insensitive language, so you can use uppercase or lowercase letters for the keywords and operators.
