C- Operator and their uses with examples

1. Unary Operator

a) num-- means decrement of 5 to 4 as an example! :)

// Online C compiler to run C program online

#include <stdio.h>

int main() {

   int num = 5;

   

   printf("The value of 5 before decrement is:- %d", num);

   printf("\nThe value of 5 using decrement is:- %d", num--);

   printf("\nThe value of 5 after decrement is:- %d", num);

   

    return 0;

}

OUTPUT:-

The value of 5 before decrement is:- 5

The value of 5 using decrement is:- 5

The value of 5 after decrement is:- 4

=== Code Execution Successful ===

b) num++ is the vice-e-versa of num--

// Online C compiler to run C program online

#include <stdio.h>

int main() {

   int num = 5;

   

   printf("The value of 5 before decrement is:- %d", num);

   printf("\nThe value of 5 using decrement is:- %d", num++);

   printf("\nThe value of 5 after decrement is:- %d", num);

   

    return 0;

}

OUTPUT :-

The value of 5 before decrement is:- 5

The value of 5 using decrement is:- 5

The value of 5 after decrement is:- 6

=== Code Execution Successful ===
