C Quiz - 103

Question 1

For a given integer, which of the following operators can be used to “set” and “reset” a particular bit respectively?

• | and &
• && and ||
• & and |
• || and &&

Question 2

What’s going to happen when we compile and run the following C program snippet?

C

#include \"stdio.h\"
int main()
{
 int a = 10;
 int b = 15;

 printf(\"=%d\",(a+1),(b=a+2));
 printf(\" %d=\",b);

 return 0;
}

• =11 15=
• =11 12=
• Compiler Error due to (b=a+2) in the first printf().
• No compile error but output would be =11 X= where X would depend on compiler implementation.

Question 3

What’s going to happen when we compile and run the following C program snippet?

C

#include \"stdio.h\"
int main()
{
 int a = 10;

 printf(\"=%d %d=\",(a+1));

 return 0;
}

• =11 0=
• =11 X= where X would depend on Compiler implementation
• Undefined behavior
• Compiler Error due to missing argument for second %d

Question 4

Which of the following functions from “stdio.h” can be used in place of printf()?

• fputs() with FILE stream as stdout.
• fprintf() with FILE stream as stdout.
• fwrite() with FILE stream as stdout.
• All of the above three - a, b and c.
• In “stdio.h”, there’s no other equivalent function of printf().
