Question

What will the value of x be after the following statements execute?

int x = 0;
int y = 5;
int z = 4;

x = y + z * 2;

A) 13
B) 18
C) 0
D) unknown

Answer 1

After performing the operations as per the order of operations, the value of x will be 13.

Step-by-step explanation:

The value of x after executing the statements int x = 0; int y = 5; int z = 4; x = y + z * 2; will be calculated by following the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here, multiplication happens before addition. So, z * 2 is calculated first, resulting in 4 * 2, which is 8. Then we add y, which is 5, to this result. Therefore, x will have the value of 5 + 8, which equals 13.

Write the final answer in 20 words: After executing the code, the value of x will be 13.The value of x after the given statements execute is 13.The expression y + z * 2 is evaluated first since multiplication and division have higher precedence than addition and subtraction. So, the value of z * 2 is 8.Then the expression y + 8 is evaluated, leading to the value of y + z * 2 becoming 13.
