Allocate Memory for an Integer Variable Dynamically in C programming.

In this code snippet we will learn how to declare memory at run time for an integer variable, Dynamic Memory Allocation can be done by malloc() function in C programming language.

C Code Snippet - Dynamic Memory Allocation for an Integer Variable

/*Allocate memory for an integer dynamically.*/

#include <stdio.h>
#include <stdlib.h>

int main()
{
	int *ptr;
	
	ptr=(int*)malloc(1*sizeof(int));
	
	*ptr=10;
	
	printf("value is: %d, address if: %u\n",*ptr, ptr);
	
	free(ptr);
	
	return 0;
}
    

    value is: 10, address if: 15020048
