malloc c++ example
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
int *ptr;
ptr = (int*) malloc(5*sizeof(int));
if(!ptr)
{
cout << "Memory Allocation Failed";
exit(1);
}
cout << "Initializing values..." << endl << endl;
for (int i=0; i<5; i++)
{
ptr[i] = i*2+1;
}
cout << "Initialized values" << endl;
for (int i=0; i<5; i++)
{
/* ptr[i] and *(ptr+i) can be used interchangeably */
cout << *(ptr+i) << endl;
}
free(ptr);
return 0;
}malloc() in c and c++
/* malloc example: random string generator*/
#include <stdio.h> /* printf, scanf, NULL */
#include <stdlib.h> /* malloc, free, rand */
int main ()
{
int i,n;
char * buffer;
printf ("How long do you want the string? ");
scanf ("%d", &i);
buffer = (char*) malloc (i+1);
if (buffer==NULL) exit (1);
for (n=0; n<i; n++)
buffer[n]=rand()%26+'a';
buffer[i]='\0';
printf ("Random string: %s\n",buffer);
free (buffer);
return 0;
}cpp malloc
int alloc_size = 10;
int* buffer = (int*) malloc (alloc_size);
//Allocate memory block which can fit 10 integersmalloc c++ program
