Consider the following C code:

#include <stdio.h>
int *assignval(int *x, int val)   {
*x = val;
return x;
}
void main ( )  {
int  *x = malloc(sizeof(int));
if(NULL == x)  return;
x = assignval(x, 0);
if(x)  {
x = (int *)malloc(size of(int));
if(NULL == x)  return;
x = assignval(x, 10);
}
printf("%dn",  *x);
free(x);
}

The code suffers from which one of the following problems: 2017 SET 1 ||MCQ || 1-mark

compiler error as the return of malloc is not typecast approximately

compiler error because the comparison should be made as x==NULL and not as shown

compiles successfully but execution may result in dangling pointer

compiles successfully but execution may result in memory leak
