Marks: 5

Year: 2019 Final TU FOHSS

1. What is DMA? (Definition + Key Points) Definition DMA (Dynamic Memory Allocation) is the process of allocating memory at runtime using functions from <stdlib.h> in C. It allows a program to requ

Question 2

1. Define Pointer Definition A pointer is a variable that stores the memory address of another variable. Pointers allow direct access and manipulation of memory, which is useful for dynamic memory,

Question 3

How will you define pointer? Write a program that illustrate how pointer variable change the value of normal variable.

1. Definition of Pointer A pointer is a special variable that stores the memory address of another variable. Pointers allow indirect access to data and enable operations like dynamic memory allocati

Question 4

Why do you use DMA instead of array? Explain DMA with suitable example.

Marks: 5

1. Why Use DMA Instead of Array? DMA (Dynamic Memory Allocation) is used when the amount of memory needed cannot be known in advance. Static arrays have fixed size decided at compile time, while DMA

Question 5

Write a C program to store the player name, runs scored, wickets taken of 20 cricketers using structure along with pointer then arrange the players in order of maximum wickets to minimum wickets they

Definition Structure A structure is a user-defined data type in C that groups variables of different data types under a single name. Pointer to Structure A pointer to structure is a pointer variable t

Question 6

Why DMA is used in C language? Write a program to enter age of 20 students and count age between 18 and 25 from the array using DMA functions.

Marks: 5

Year: 2021 Final TU FOHSS

1. Why DMA is Used in C Dynamic Memory Allocation (DMA) allows a program to allocate memory at runtime rather than compile time. Key Points - Useful when size of data is unknown during compilation.

Question 7

What is the advantage of pointer? Write a C program to store 10 integers into memory and find out minimum and maximum using dynamic memory allocation (DMA).

Marks: 5

1. Advantages of Pointer Pointers are variables that store the memory address of other variables. Key Advantages: - Dynamic memory allocation (DMA): Allocate memory at runtime. - Efficient array a
