Hide user input, and only allow certain characters

Question

Is there any way to hide user input when asked for in C? For example:

char *str = malloc(sizeof(char *));
printf(\"Enter something: \");
scanf(\"%s\", str);g         


        

Answer 1

For the sake of completeness: There is no way to do this in C. (That is, standard, plain C without any platform-specific libraries or extensions.)

You did not state why you wanted to do this (or on what platform), so it's hard to make relevant suggestions. You could try a console UI library or a GUI library. You could also try your platform's console libraries. (Windows, Linux)
