wsprintf(c_buffer, _T("%d"), pb->i_id);

sprintf(c_buffer, "%d", pb->i_id);

_stprintf(c_buffer, _T("%d"), pb->i_id);

However, the swprintf function, which is a VC++ library function is the correct one to use.
The wsprintf function is part of some windows API, and does not support all the formatting options. For example wsprintf does not support the "*" width specification.

char string[20];
printf("%s", &string);    // The & is not needed here.

void fun(char** arg)
{
    printf("%s", *arg);      // * is needed here.
}

• Quote:

  float* random_seq=(float *)malloc(SizeOfData* sizeof(float ));

  
  is useless, since memory is allocated inside the random1 function.



• You never free the allocated memory (you have to ).
