Relational Operators in C ++

Relational Operators in C++

Relational operators in C++ are used to compare values and determine their relationship to each other. They are fundamental for decision-making and control flow in C++ programs. Here's a breakdown:

List of Relational Operators:

 * == (Equal to): Checks if two values are equal.

 * != (Not equal to): Checks if two values are not equal.

 * > (Greater than): Checks if the left-hand operand is greater than the right-hand operand.

 * < (Less than): Checks if the left-hand operand is less than the right-hand operand.

 * >= (Greater than or equal to): Checks if the left-hand operand is greater than or equal to the right-hand operand.

 * <= (Less than or equal to): Checks if the left-hand operand is less than or equal to the right-hand operand.

How they work:

 * Comparison: Relational operators compare two operands.

 * Result: The result of a relational operation is always a boolean value (true or false).

 * Usage: The result of the comparison is often used in conditional statements (like if, else if, else) to control the flow of the program.

Examples:

int a = 10;

int b = 5;

// Comparisons

bool isEqual = (a == b);          // false

bool isNotEqual = (a != b);       // true

bool isGreater = (a > b);         // true

bool isLess = (a < b);           // false

bool isGreaterOrEqual = (a >= b);  // true

bool isLessOrEqual = (a <= b);     // false

// Using in if statement

if (a > b) {

    cout << "a is greater than b" << endl;

} else {

    cout << "a is not greater than b" << endl;

}

Important Notes:

 * Relational operators can be used with various data types, such as integers, floating-point numbers, characters, and even user-defined objects (if appropriate comparison operators are defined for those objects).

 * Be mindful of data type conversions when comparing values of different types. Implicit or explicit conversions may occur, potentially affecting the comparison result.
