Question

Consider the following code fragment. The while loop condition would involve myBoolVar.

bool myBoolVar = true;

while ( condition ) {

//code

}

Which is not a valid condition to use in the while loop ?

1. while (myBoolVar==1)

2. while (myBoolVar==true)

3. while (myBoolVar)

4. while (!myBoolVar=0)

Based on the following lines of “C” code, what is the value of result after line 4?

unsigned int p = 24;

unsigned int d = 16;

unsigned int result = 0;

result = p % d;

A. 8

B. 9

C. 1

D. 2

Explanation / Answer

Answer

4. while (!myBoolVar=0)

// InValid: We need to compare the values but assignment is given here

Explanation

1. while (myBoolVar==1) // Valid: Equavalent of true is 1

2. while (myBoolVar==true) // Valid: Directly checking

3. while (myBoolVar) // Valid: When we simply give 1 / true, loop works

Answer: 8

Explanation: p % d = 24 % 16 = remainder when 16 divides 24 = 8
