## Comparing numbers
In programming, we can compare values using the following operators:
• Operator < (less than)
• Operator > (greater than)
• Operator <= (less than or equals)
• Operator >= (greater than or equals)
• Operator == (equals)
• Operator != (inequals)
When compared the result is boolean value true or f... | {} |
