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 <stdio.h>

  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.
