about malloc

Hi

When we use malloc then the memory allocated is continuous or not?
Is there anyway to know it?

It is continous only why because u are giving array type var......

[B]Yes malloc() allocates memory in contiguous location.[/B]
To verify it see this program

#include<stdio.h>
void main()
{
int *p;
int i;
p=(int *)malloc(5);
i=1;
while(i <5)
printf("\t&#37;u",p++);
}
Now depending upon the computer processor architecture(32,64 bit).the specified size of memory would be allocated for an integer. Suppose 32 bit machine (sizeof of int = 2 bytes) and starting location of allocated space be 1000.
Then the output would be [B]1000 1002 1004 1006 1008[/B]

Memory allocated by individual [font="Courier New"]malloc()[/font] calls should be contiguous. That doesn't hold for multiple calls, though. For example, given the code

[code]
char *p = malloc(10);
char *q = malloc(20);
[/code]

all 10 bytes of p should be contiguous and all 20 bytes of q should be contiguous, but there's no guarantee that p and q form a contiguous 30-byte block.
