In the C programming language, dynamic memory allocation for an array can be achieved using functions like `malloc`, `calloc`, or `realloc`. These functions allow programmers to allocate memory at runtime, providing flexibility in managing memory resources.
Consider the following example using `malloc`:
#include <stdio.h>
#include <stdlib.h>
int main() {
int n;…
In C, the malloc() function is utilized to dynamically allocate memory for an array. This process enables the creation of arrays whose size is determined during runtime rather than compile time. Consider the following example:
#include <stdio.h>
#include <stdlib.h>
int main() {
int *array;
int size;
printf("Enter the size of the array: ");
scanf("%d", &size);
// Dynamically allocate memory for the array
array = (int *)malloc(size * sizeof(int));
if (array == NULL) {
printf("Memory allocation failed. Exiting...\n");
return 1;
}
// Initialize the array elements
for (int i = 0; i < size; i++) {
array[i] = i * 10; // Just an example initialization
}
// Access and print the array elements
printf("Array elements: ");
for (int i = 0; i < size; i++) {
printf("%d ", array[i]);
}
printf("\n");
// Free the allocated memory
free(array);
return 0;
}
This program prompts the user to input the size of the array. It then allocates memory for the array dynamically using malloc(). After initializing and printing the array elements, it deallocates the memory using free() to avoid memory leaks. Dynamic memory allocation with malloc() provides flexibility in managing memory resources, especially when dealing with arrays of varying sizes at runtime.
The C programming language leverages the malloc() function to dynamically allocate memory for arrays, offering flexibility in managing memory resources at runtime. Here's an illustrative example showcasing this capability:
#include <stdio.h>
#include <stdlib.h>
int main() {
int *array;
int size;
printf("Enter the desired size of the array: ");
scanf("%d", &size);

Computer networking refers to the practice of connecting various computing devices to share resources, exchange data, and communicate with each other. It enables devices, such as computers, servers, smartphones, and other peripherals, to communicate and interact with each other locally or across long distances. Networks can range from small local…
Software can be categorized into various types based on their functions and usage. These types include:
1. System Software:
- Operating Systems: Manage hardware resources and provide essential services for computer programs. Examples include Windows, macOS, Linux, iOS, and Android.
- Device Drivers: Facilitate communication between hardware devices and …
