Masking Text while scanning - C -


i have prompt user password, when entering password want characters masked, have created code characters masked until enter key pressed. character array pwd not reading characters guess!

char pwd[10]; while(ch!=13) {      pwd[i] = ch;      ch = '*' ;      printf("%c",ch);      ch=getch();      i++; } pwd[i]='\0'; printf("%s",pwd);

nothing printed when try print pwd.

as @olaf , @eugenesh. mentioned, terrible way passwords. said, here's help.

assuming being initialized somewhere, move "pwd[i] = ch" end of loop before "i++" whole thing should (note still wrong):

char pwd[10]; while(ch!=13) {      ch = '*' ;      printf("%c",ch);      ch=getch();      pwd[i] = ch;      i++; } pwd[i]='\0'; printf("%s",pwd);

i print "*" after user enters character. let's fix other problems while we're @ it.

int = 0;    /* since didn't specify if initialized */ char pwd[15]; /* setting 10 have caused overrun                 buffer.  not crashy, it's huge                  source of security holes.  let's not that. */ /* unless you're waiting user enter in     character happens ascii 13, you'll     never out.  let's change since     i'm guessing want 13 character password. */ while(i != 13)   {      char ch=getch();      pwd[i++] = ch; /* can post increment right here don't                       have @ end of loop                       might forget */      printf("*");      fflush(stdout);  /* since using printf stdout (not                           stderr, need manually flush stdout or                           things won't show until newline                           printed. */ } printf("\n"); /* print newline don't end printing                   password on same line */  pwd[14]='\0'; printf("password entered our crappy security system: %s",pwd);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
