how to use getch in niosII

What you want to achieve with this getch()?

How does the getchar() gon't suite your need?

May be you can post your code here?

Yes, now i trying to use getchar() but there still some problem with it because i using "string" to do it but when i change to "int" or "char" it can be done. The problem is when i using string the password that i type out is correct (i already prove by typing: printf (%s, &password) ) but it still cant be match with the password that i had set. I making a program that need to type password to log in, when typing password those character will become ***, by the way i still dun know the programming change to *** is correct or not. Thx for helping

my coding show as below:# include <stdio.h># include <stdlib.h># include <unistd.h># include <string.h>

void one();

void two();

int login ;

int user ;

char password[10];

int i = 0;

char c;

int main ()

{

while(1){

printf ("---------------------------\n");

printf (" Main Menu\n");

printf ("----------------------------\n");

printf (" 1.Admin login\n 2.User login\n");

scanf("%i", &login);

if (login == 1)

two();

if (login == 2)

printf ("Display\n");

}

return(0);

}

void one()

{

menu:

printf ("---------------------------\n");

printf (" User Menu\n");

printf ("----------------------------\n");

printf (" 1.Check User\n 2.Delete User\n 0.Main Menu\n");

scanf("%i", &user);

if (user == 1)

printf ("CHECK\n");

else if (user == 2)

{

printf ("DELETE\n");

}

else if (user == 0)

main ();

else if (user != 1,2,0)

{

printf ("Wrong key please retry\n");

goto menu;

}

else

NULL;

}

void two()

{

printf ("Please enter password: ");

enter:

scanf("%s", &password);

{

while(i<5){

c = getchar();

password = c;

printf("*");

i++;

}

getchar();

i=0;

while (i<5)

{

printf("%c",pass);

i++;

}

getchar();

}

if (password == 'obc')

{

one();

}

else if (password != 'obc')

{

printf ("Wrong password, please retype ");

goto enter;

}

else

NULL;

}

ps: previously those getchar i use getch for it
