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

float x;
x = 1. / 2 * 3;
/***
  • 1.5
  • 1
  • 2
  • 0
Explanation & Hints:

To determine the value of the x variable in the given snippet, we need to evaluate the expression x = 1. / 2 * 3;.

Here, the expression involves:

  1. 1. which is a floating-point number equivalent to 1.0.
  2. Division by 2, resulting in 1.0 / 2 = 0.5.
  3. Multiplication of the result by 3, leading to 0.5 * 3 = 1.5.

Thus, the value of x at the end of this snippet will be 1.5.

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

int x;
x = 1 / 2;
  • 0
  • 1
  • 2
  • 0.5
Explanation & Hints:

Let’s break down the assignment:

int x;
x = 1 / 2;
  • 1 / 2 is an integer division. Since both 1 and 2 are integers, the result is also an integer.
  • 1 / 2 equals 0 in integer division because the fractional part (0.5) is discarded.

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

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

int x;

/* */
  • 0
  • 1
  • 2
  • 1.5
Explanation & Hints:

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

int x;
x = 1 / 2 * 3;

In C, the operations are performed from left to right due to the same precedence level (both / and * have the same precedence and associate left to right):

  1. Integer division:
    • 1 / 2 is an integer division. Since both 1 and 2 are integers, the result is also an integer.
    • 1 / 2 equals 0 in integer division because the fractional part (0.5) is discarded.
  2. Multiplication:
    • The result of the division (0) is then multiplied by 3.
    • 0 * 3 equals 0.

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