1. Recursion is

Calling a function again and again till base condition is met

Calling a function

Calling a block of code

Recursion cannot be implemented in C

Recursion is the process of calling a function repeatedly until a specific condition, known as the base condition, is met. In this process, the function calls itself, creating a loop-like behavior. This allows for the repetition of a certain block of code without the need for explicit iteration. Recursion is commonly used in programming to solve problems that can be broken down into smaller, similar subproblems.

2. What is the following statement in bold called as? void f1(); void main() { f1(); }

Function prototype

Function call

Function definition

None of the above

In the given code, the statement in bold "void f1();" is called a function prototype. A function prototype is a declaration of a function that specifies the function's name, return type, and parameters (if any), but does not include the function's body. It allows the compiler to know about the existence of the function before it is actually defined or called. In this case, the function prototype is declaring a function named "f1" which takes no arguments and returns void.

5. Size of the following structure structure student { char name[50]; int id; char subject[15]; };

50

4

15

69

The size of the structure "student" is 69 bytes. This is because the structure contains three variables: "name" which is an array of characters with a size of 50 bytes, "id" which is an integer with a size of 4 bytes, and "subject" which is an array of characters with a size of 15 bytes. Therefore, the total size of the structure is 50 + 4 + 15 = 69 bytes.
