Participating in a C quiz can offer several benefits for individuals looking to improve their programming skills and knowledge of the C programming language. Here are some potential advantages:
- Skill Enhancement: Quizzes often cover a range of topics within C programming, allowing participants to test and enhance their skills in areas such as syntax, data types, control structures, functions, and more.
- Knowledge Validation: Quizzes can help individuals gauge their understanding of key concepts in C programming. By answering questions, participants can identify areas where they need to focus on improving their knowledge.
C Quiz 01 to 07
Q-01: Can a program be invoked from another program?
(A) True
(B) False
(A) True (a program can invoke another program using system calls.)
Q-02: What will be printed as the result of the operation below:

Q-03: How many times main() will get called?
main()
{
printf("\n Main Called Again");
main();
}
(A) 1
(B) 100
(C) main can not be called recursively
(D) Infinite
(D) Infinite (There is no condition in the main() to stop the recursive calling of the main() hence it will be called infinite no of times.)

11 ^ 5
What does the operation shown above produce?
(A) 1
(B) 6
(C) 8
(D) 14
Ans :(D) 14
C Quiz 08 to 14
Q-08
Suppose a,b,c are integer variables with values 5,6,7 respectively.
What is the value of the expression : !((b+c)>(a+10))
(A) 1
(B) 6
(C) 15
(D) 0
Let's break down the expression and substitute the given values:
The expression is: !((b + c) > (a + 10))
Given values:
a = 5
b = 6
c = 7
Substitute these values into the expression:
!((6 + 7) > (5 + 10))
Now, perform the operations inside the parentheses:
!(13 > 15)
Finally, compare 13 and 15:
!(false)
The logical NOT (!) operator negates the result, so the final value of the expression is true.
Q-09: How many variable scopes are there in “C” language?
(A) 2
(B) 3
(C) 4
(D) 5
Ans ; (C) 4 [body, function, program and file scope in “C”. ]
