malloc returns a void pointer. It needs to be cast to char*
before allocating it to char* variable.
char *p = (char *)malloc(10); should do fine.

Answer / poornima

Nothing wrong.Its fine..
if u hve further doubt run the below code.

#include<stdio.h>
int main()
{
char *p=malloc(10);
if(p==NULL)
{
printf("malloc failed");
exit(0);
}
else
{
printf("malloc success\n");
p="hai";
printf("%s",p);
}
return 0;
}
