This can be done in several ways, depending on the needs: Zeroing out memory: Use memset() right after allocation to fill the memory with zeros. Example: int *arr = malloc(10 * sizeof(int)); if (arr != NULL) { memset(arr, 0, 10 * sizeof(int)); } Copying data immediately ...

The malloc() function in C++ allocates a block of uninitialized memory to a pointer. It is defined in the cstdlib header file. Example #include <iostream> #include <cstdlib> using namespace std; int main() { // allocate memory of int size to an int pointer int* ptr = (int*) ...
How to Create an Array of Strings Using “malloc()” in C Programming? To create an array of strings and assign it a memory block through the “malloc()” function, look at the provided example. Step 1: Create an Array of String Using “malloc()” Function To create an array of stri...
Example program Given below is the C program to demonstrate dynamic memory allocation function - malloc(). Live Demo #include<stdio.h> #include<stdlib.h> void main(){ //Declaring variables and pointer// int numofele,i; int *p; //Reading elements as I/p// printf("Enter the number of...
Program to create a dynamic memory using the malloc() functionLet's consider an example of taking the size as an input from the user and then entering data at the run time using the malloc () function in the C programming language.
newis an operator in C++ programming language, it is also used to declare memory for N blocks at run time. Example of new This program will declare memory for 5 integers at run time using new operator, read 5 numbers and print them. ...
