Answer 1

You are writing to memory that wasn't properly allocated to the string yet. You need to resize the string like so:

string password;
int length = 5;
password.resize(length);

Or you can add to the string instead:

password += ascii_char;

Answer 2

@Mustafa K.
Yes, you surely can.
Assume lower end of range as L and upper range as U. Then, the formula with rand() is:

int x = L + ( rand()%(U-L+1) );

Eg -

int x = 15+rand()%6;
// Returns number between 15 and 20.

Answer 3

Not sure, but I think you can't use "password[i]", you can i.e. use "password += ascii_char" or a string function "add" if i'm correct. Also there's no need for a "for" loop with "j".

Answer 4

thnks for answers, i want one more thing, can i produce random number between x and y ?
