What is the value of balance after the following code isexecuted?

int balance=10;

while (balance>=1) {

if (balance<9) break;

balance=balance - 9;

}

A. - 1

B. 0

C. 1

D. 2

C. 1

Explanation:

Code

int balance=10;

while (balance>=1)

{

break;

balance=balance - 9;

}

We are initializing variable 'balance' of integer type with value 10 in the first line of code. int balance=10;

Then we will check balance value (10) with 1 in While loop.

while (balance>=1)

while (10>=1)

So, 10 is greater than 1. we will get into this loop.

In loop, there is if condition, we will put balance value and check the condition.

if (balance<9)

if (10<9)

So 10 is greater than 9, so this condition fails and we will not get into this condition.

After the if condition, We will get the arithmetic line of code -

balance=balance - 9;

In code, balance value is 10 then applying the value in this line-

balance=10 - 9;

So, the balance value is updated as 1.

So, there is no line of code are left in loop, we will again check the while loop's condition

while (balance>=1)

while (1>=1)

As 1 is equal to 1, this condition is true and we will get into the loop

In loop, there is if condition, we will put balance value and check the condition.

if (balance<9)

if (1<9)

So 1 is smaller than 9, so this condition is true and we will get into this condition.

break;

We will encounter break statement, this statement is used to terminate the loop. So, it will terminate the while loop and final updated balance value will be 1.

C program for verifying this code

#include

int main ()

{

int balance=10;

while (balance>=1)

{

if (balance<9)

break;

balance=balance-9;

}

printf ("%d", balance);

return 0;

}

//You can copy this code and check on any ide.

Output

1
