    Relational Operators

    • Relational operators are used to compare numeric and char values to determine their relative order.
    • There are six relational operators:
      • Greater than: >
      • Less than: <
      • Greater than or equal to: >=
    • Example: 5 > 7 is false, 7 > 5 is true.
