C Programming Concepts

What is a return statement?

• A statement that pauses a function execution.

• A statement that ends a function and gives a value back to where the function was called.

• A statement that creates a new variable.

• A statement that loops through a set of values.

What are Parameters of a function?

• Parameters are variables used in a function's definition to hold the values passed.

• Parameters are the return values of a function.

• Parameters are the functions that call other functions.

• Parameters are the data types defined in a function.

Differentiate between Global and Local Variables.

• Global Variable: Declared inside a function, accessible only within the function. Local Variable: Declared outside all functions, accessible from any function.

• Global Variable: Declared outside all functions, accessible from any function. Local Variable: Declared inside a function, accessible only within the function.

• Global Variable: A variable that can only be accessed in the main program. Local Variable: A variable that can be accessed anywhere in the program.

• Global Variable: A variable that retains its value throughout the program. Local Variable: A variable that loses its value after the function ends.

What is Call by Reference?

• When a function is called by reference, the address of the actual argument variables passed, instead of their values.

• When a function is called by value, the actual values of the arguments are passed to the function.

• When a function is called, it creates a copy of the variable in memory.

• When a function is called, it directly modifies the original variable without any reference.

What are the members of the class?

• Data members are the data variables declared inside the class and member functions are the functions declared inside the class.

• Members of the class are the objects created from the class.

• Members of the class are the attributes that define the class's behavior.

• Members of the class are the methods that can be called on the class.

What is arrow operator?

• A type of arrow used in graphics

• A member selection operator

• An operator for creating arrows in programming

• A symbol for indicating direction

What is recursion?

• A function that calls itself is known as a recursive function and this technique is known as recursion in C programming.

• A method of solving problems by breaking them down into smaller subproblems that can be solved independently.

• A programming technique that involves using loops to repeat a set of instructions until a condition is met.

• A way to optimize code by eliminating unnecessary function calls.

What is a Function in C?

• A function is a set of instructions that performs a task.

• A function is a variable that stores data.

• A function is a type of loop used for iteration.

• A function is a way to define a class in C.

Explain the concept of user defined and pre-defined (library) functions.

• Library functions are user-created functions for specific tasks.

• User-defined functions are pre-written functions provided by C's standard library.

• Library functions are pre-written functions provided by C's standard library. User-defined functions are functions created by the programmer to perform specific tasks.

• User-defined functions are functions that cannot be modified by the programmer.

What are Arguments of a function?

• Arguments are the actual values or data that you pass into a function when you call it.

• Arguments are the names of the variables defined in a function.

• Arguments are the functions that are called within another function.

• Arguments are the return values of a function.
