The "C language" detects how much space malloc can allocate.

method One:

#include <stdio.h>#include <stdlib.h>int main (){    int0;    while(malloc(1<<20))    {        count++;    }    printf("%d\n",count);    return0;}

Method Two:

#include<stdio.h>#include <stdlib.h>int main (){    intcount0;    for(count0count++)    {        if( !malloc(1<<20) )        {            break;        }    }    printf("%d\n",count);    return0;}

The malloc function is called to dynamically allocate one megabyte of memory space at a time, and when the malloc function returns a value of NULL, the description can no longer be allocated.
