Operator Precedence in Logical Operators

Relational operators are used to compare two values. The precedence of relational operators from highest to lowest is as follows:

Less than, greater than, less than or equal to, greater than or equal to < > <= >=
Equality and inequality == !=

Below is the implementation of Operator Precedence in Relational Operators:

C++

#include <iostream>
using namespace std;

int main()
{
    int a = 15;
    int b = 20;
    int c = 35;

    // Using relational operators
    // b < c is evaluated first, which results to 1 and then
    // 1 != 35 is evaluated which results to true
    bool result1 = b < c != c;
    // c != c is evaluated first, which results to 0 and
    // then 20 < 0 is evaluated which results to false
    bool result2 = b < (c != c);

    // Print the results
    cout << "(b < c != c) = " << result1 << endl;
    cout << "(b < (c != c)) = " << result2 << endl;

    return 0;
}

Output

a < b: 1
b > c: 0
a <= c: 1
c >= b: 1
a == b: 0
b != c: 1

Operator Precedence in Programming

Operator Precedence, also known as operator hierarchy, is a set of rules that controls the order in which operations are performed in an expression without parentheses. It is a fundamental concept in programming languages and is crucial for writing correct and efficient code.
