Output of the Code

What will be the output of the code given below?

If the input is 5, what is the output?

    int x;
    int z=0;
    scanf("%d", &x);
    if(x > 9) {
      z = 3;
    }
    z = z + 1;
    printf("%d",z);
  

a. 0

b. 1

c. 3

d. 4

Final answer:

If the input is 5, then the output of the code given will be 1. Option b is the answer.

Explanation:

The output will be 1. The code provided takes an input from the user and stores it in the variable x. If x is greater than 9, the variable z is assigned a value of 3. Regardless of the value of x, z is always incremented by 1. Finally, the value of z is printed.

In this case, the input is 5 which is not greater than 9, so the initial value of z which is 0, will be incremented by 1. Therefore, the output will be 1.

The given code takes user input and increments a variable based on a condition. As the input is not greater than 9, the code increments and outputs 1. This demonstrates how control flow impacts the output of the program.

Option b is the answer.
