Q8) A type of function that is written by the programmer is known as:

1. User- defined
2. Subprograms
3. Subroutine
4. Built- in- fuction

Answer:User- defined

Explanation:A type of function that is written by the programmer is known as a user-defined function. These functions are created by the programmer to perform specific tasks or operations that are not provided by the built-in functions of the programming language. User-defined functions can be called multiple times from different parts of a program, making them a powerful tool for organizing and structuring code.

Q9) The Keyword used to specify the value returned by a function is:

1. Return
2. Continue
3. Satie
4. Break

Answer:Return

Explanation:The keyword used to specify the value returned by a function in C is "return".

Q10) A function can Reture _________ value.

1. 1
2. 4
3. 3
4. 2

Answer:1

Explanation:A function can return a single value in C programming language.

Q11) A built in function:

1. Cannot be redefined
2. Can be redefined
3. Should be redefined
4. Cannot retum value

Answer:Cannot be redefined

Explanation:A built-in function is a function that is included in the programming language's standard library, which can be called directly from a program without the need for the programmer to write the function's implementation from scratch. Examples of built-in functions in C include printf, scanf, sqrt, sin, cos, etc.

Q12) Memory allocated to a local variable at the time of its:

1. Declaration
2. Firsi refi
3. Static variable
4. Definition

Answer:Declaration

Explanation:In C and C++, local variables are typically declared at the beginning of a function, but the memory is allocated when the function is called and is deallocated when the function returns.

Q13) The scope of variable refers to its:

1. bere
2. Accessibitity
3. Name
4. Length

Answer:Accessibitity

Explanation:The scope of a variable refers to its visibility or accessibility within a program. It determines where the variable can be accessed and used in the program. In C language, there are three types of scope:

Q14) Another name of built in function is: . - (AIKA

1. Library function
2. Arithmetic function
3. User defined function
4. All of these

Answer:Library function

Explanation:Standard library function.

Q15) Function declaration is also known as function:

1. Definition
2. Header
3. Parameters
4. Prototype

Answer:Prototype

Explanation:A function prototype is a declaration of the function that specifies the function's name, return type, and parameters, but does not contain the function body.

Q16) Function that are the part of language are called:

1. Intrinsic
2. Language defined
3. Built in Function
4. All these

Answer:Built in Function

Explanation:Functions that are part of a programming language and are available for use without needing to be explicitly defined are called built-in functions or library functions or as well as Built in Function.

Q17) The first line of User-defined function is:

1. Arguments
2. Header
3. Calling
4. Prototype

Answer:Header

Explanation:The first line of a user-defined function in C programming language is the function header, which includes the function name, return type, and parameter list (if any). For example:

int addNumbers(int a, int b) {

Q18) The set of statement in curly braces in a loop is known as ___ of the loop:

1. Title
2. Header
3. Center
4. Body

Answer:Body

Explanation:The set of statements in curly braces in a loop is known as the loop body.

Q19) Which provides information about the function to the compiler:

1. Function prototype
2. Function call
3. Function body
4. Function header

Answer:Function prototype

Explanation:The function prototype provides information about the function to the compiler. It includes the function name, return type, and the type and order of its parameters.

Q21) Local Variables are also called:

1. Automatic variables
2. Static variable
3. Register variable

Answer: Automatic variables

Explanation:Local variables are created and destroyed automatically with function calls, storing data within the function's scope and inaccessible outside of it, without requiring manual memory management. .

Q22) Global variable are created in:

1. ROM
2. Hard disk
3. Cache
4. RAM

Answer:RAM

Explanation:Global variables are defined outside functions, accessible throughout the program, and persist until the program terminates, enabling data sharing across functions and modules. .

Answer:RAM

Explanation:Yes It's True: variables are created in the Random Access Memory (RAM) of a computer. When a variable is declared or initialized in a program, a portion of memory is allocated to store its value.
