Unary Operators in C

Here are the implementation of Unary Operator in C language:

#include <stdio.h>

int main()
{
    int a = 10;
    int b = 5;

    // Unary increment (++)
    // Increment 'a' by 1 before using its value
    printf("Unary Increment: %d\n", ++a);
    // 'a' has been incremented
    printf("a after increment: %d\n", a);

    // Unary decrement (--)
    // Decrement 'b' by 1 before using its value
    printf("Unary Decrement: %d\n", --b);
    // 'b' has been decremented
    printf("b after decrement: %d\n", b);

    // Unary plus (+)
    int c = -5;
    // The unary plus doesn't change the value of 'c'
    printf("Unary Plus: %d\n", +c);

    // Unary minus (-)
    // The unary minus negates the value of 'c'
    printf("Unary Minus: %d\n", -c);

    // Unary logical NOT (!)
    int d = 0;
    // Logical NOT of 0 is 1 (true)
    printf("Unary Logical NOT: %d\n", !d);

    // Unary bitwise NOT (~)
    unsigned int e = 1;
    // Bitwise NOT of 1 is UINT_MAX - 1
    printf("Unary Bitwise NOT: %u\n", ~e);

    return 0;
}

Output

Unary Increment: 11
a after increment: 11
Unary Decrement: 4
b after decrement: 4
Unary Plus: -5
Unary Minus: 5
Unary Logical NOT: 1
Unary Bitwise NOT: 4294967294

Unary Operators in Programming

In programming, operators act as powerful tools for manipulating data and performing various operations. Among these, unary operators stand out, functioning on a single operand to transform or evaluate data in different ways. This post explains the types, implementations, and best practices associated with unary operators across several programming languages.
