Questions will be look like this:

All are multiple choice questions which contain 4 options. With answer along with that explanation.

Q1. What is the lifetime of a variable declared with the static keyword inside a function?

Ans. Until the file ends

Overall explanation: A variable declared with the static keyword inside a function retains its value until the program ends.

Q2. Which of the following is the correct way to define a function that returns a pointer?

Ans. int* func()

Overall explanation: A function that returns a pointer is defined with the syntax int* func(), where int* indicates that the function returns a pointer to an integer.

Q3. What is the impact of excessive use of inline functions?

Ans. Increased code size

Overall explanation: Excessive use of inline functions can lead to increased code size because the function code is duplicated at each point of the function call, which may negate the performance benefits and could cause cache misses.

Q4. How do you declare a union in C?

Ans. union { Data; int i; float f; char c; };

Overall explanation: A union in C is declared using the union keyword followed by the union name and the members within curly braces. For example: union Data { int i; float f; char c; };. All members share the same memory space, so only one member can be used at a time.
