C++ Programming Code Examples

A relational operator is used to check the relationship between two operands. C++ Relational Operators are used to relate or compare given operands. Relational operations are like checking if two operands are equal or not equal, greater or lesser, etc. Relational Operators are also called Comparison Operators. • == Is Equal To 4 == 9 gives us false • != Not Equal To 4 != 9 gives us true • > Greater Than 4 > 9 gives us false • < Less Than 4 < 9 gives us true • >= Greater Than or Equal To 4 >= 9 give us false • <= Less Than or Equal To 4 <= 9 gives us true Equal To Operator (==) is used to compare both operands and returns 1 if both are equal or the same, and 0 represents the operands that are not equal. The equal to == operator returns true - if both the operands are equal or the same false - if the operands are unequal int x = 10; int y = 15; int z = 10; x == y // false x == z // true The relational operator == is not the same as the assignment operator =. The assignment operator = assigns a value to a variable, constant, array, or vector. It does not compare two operands. Not Equal To Operator (!=) is the opposite of the Equal To Operator and is represented as the (!=) operator. The Not Equal To Operator compares two operands and returns 1 if both operands are not the same; otherwise, it returns 0. The not equal to != operator returns true - if both operands are unequal false - if both operands are equal. int x = 10; int y = 15; int z = 10; x != y // true x != z // false Greater than Operator (>) checks the value of the left operand is greater than the right operand, and if the statement is true, the operator is said to be the Greater Than Operator. The greater than > operator returns true - if the left operand is greater than the right false - if the left operand is less than the right int x = 10; int y = 15; x > y // false y > x // true Less than Operator (<) is used to check whether the value of the left operand is less than the right operand, and if the statement is true, the operator is known as the Less than Operator. The less than operator < returns true - if the left operand is less than the right false - if the left operand is greater than right int x = 10; int y = 15; x < y // true y < x // false Greater than Equal To Operator (>=) checks whether the left operand's value is greater than or equal to the right operand. If the statement is true, the operator is said to be the Greater than Equal to Operator. The greater than or equal to >= operator returns true - if the left operand is either greater than or equal to the right false - if the left operand is less than the right int x = 10; int y = 15; int z = 10; x >= y // false y >= x // true z >= x // true Less than Equal To Operator (<=) checks whether the value of the left operand is less than or equal to the right operand, and if the statement is true, the operator is said to be the Less than Equal To Operator. The less than or equal to operator <= returns true - if the left operand is either less than or equal to the right false - if the left operand is greater than right int x = 10; int y = 15; x > y // false y > x // true
