How to write a C program Dynamic allocation program in C programming (Example) ?
C dynamic memory allocation refers to performing manual memorymanagement for dynamic memory allocation in the C programming language via a group of functions in the C standard library, namely malloc , realloc , calloc and free .Solution:
#include <stdio.h>
#include <stdlib.h>
void swap(int *a, int *b);
int main()
{
int *x, n, i;
printf("How many numbers?\n");
scanf("%d", &n);
x = (int *)malloc(n*sizeof(int));
for(i = 0; i < n; i++)
scanf("%d", &x[i]);
free(x);
return 0;
}
void swap(int *a, int *b)
{
int temp = *a;
*a = *b;
*b = temp;
}
