How many bytes of memory will the following code reserve?
#include <stdio.h>
#include <stdlib.h>
int main()
{
int *p;
p = (int *)malloc(256 * 256);
if(p == NULL)
printf("Allocation failed");
return 0;
}
Answer: B
Hence 256*256 = 65536 is passed to malloc() function which can allocate upto 65535. So the memory allocation will be failed in 16 bit platform (Turbo C in DOS).
If you compile the same program in 32 bit platform like Linux (GCC Compiler) it may allocate the required memory
