What is the value of the var variable at the end of the following snippet?

int var;
var = 2;
var = var * var;
var = var + var;
/*
var = var / var;
var = var % var;
*/
  • 8
  • 1
  • 0
  • 16
Explanation & Hints:

To find the value of the variable var at the end of the given C code snippet, let’s walk through the code step by step:

Initialization:

int var;
var = 2;

Here, var is initialized to 2.

First Update:

var = var * var;

The value of var is squared, so 2 * 2 = 4. Now var equals 4.

Second Update:

var = var + var;

The value of var is added to itself, so 4 + 4 = 8. Now var equals 8.

The lines within the comment block are not executed, as they are commented out:

/*
var = var / var;
var = var % var;
*/

Thus, these lines do not affect the value of var.

Therefore, the value of var at the end of this snippet is 8.

What is the value of the var variable at the end of the following snippet?

int var;
var = 2;
var = var * var;
var = var + var;
var = var / var;
var = var % var;
  • 0
  • 1
  • 8
  • 16
Explanation & Hints:

Let’s break down the operations step-by-step:

int var;
var = 2;
var = var * var;
var = var + var;
var = var / var;
var = var % var;
  1. Initial value:
    • var = 2
  2. Multiplication:
    • var = var * var
    • var = 2 * 2
    • var = 4
  3. Addition:
    • var = var + var
    • var = 4 + 4
    • var = 8
  4. Division:
    • var = var / var
    • var = 8 / 8
    • var = 1
  5. Modulo:
    • var = var % var
    • var = 1 % 1
    • var = 0 (since any number modulo itself is 0)

So, the value of var at the end of the snippet is 0.
