Password system

I am trying to create a password system but I have virtually no experience. Can it be done in an understandable way?
This is my error filled code in C made in Bloodshed

#include <stdio.h>
#include <conio.h>

int main(void){
printf("type here");
while (kbhit(void)="happehfaic"); //*problem here*//
{ printf("well done");
} return 0;}

Any thoughts?

If you want to compare two elements, you use '=='.
The '=' is the assignment operator.

Thank you very much but I get this error
expected primary-expression before "void"
