Do you mean from char * to unsigned char *?

A char and a pointer are totally different.

If you mean char * to unsigned char , you can do that but you can only change the first character in the char *.

Code:

#include<stdio.h>
main()
{
        char *c="asdd";
        printf("%d\n",(unsigned char)*c);
}

Here you will get the result as 97.Because the ascii value of a is 97.

Code:

char *p;
unsigned char x;
x=(unsigned char)*p;

OR do you want:

Code:

char *p;
unsigned char *x;
x = (unsigned char *)p;

Absolutely "Yes".

The fact is, in C/C++ you can convert just about anything to just about anything else. It's all "bits", and C gives you lots of power and flexibility.

The real question (the one everybody's asking you) is:

Not *how*, but *what*? What, conceptually, is your GOAL?

We need to know the "context" of your question.

Thank you in advance .. PSM
