Answer 10

Dimwit Here, newpin1, newpin2 you declared as char and taking input with %s string but need is a intiger. So I changed as needed and it works...
[And also specify where are executing this.., this is C code you are running on c++, it works but so other some changes need depending on compiler..]

case 5:

int newpin1, newpin2; //change it at initialization..

printf("Change PIN\n");

printf("Please enter your new PIN\n");
scanf("%d",&newpin1);

printf("Please re-enter your new PIN\n");
scanf("%d",&newpin2);

//ch=getch();
if (newpin1==newpin2)
{
pin2=newpin1;
printf("Successful! Your PIN has been changed\n");
}
else
{
printf("Incorrect PIN\n");
}
goto start;
break;

Answer 11

Hello Dimwit this is Nikhil .I am posting code for Ur help please check that .
Firstly, Your code contains printf() and scanf() and you wrote code in C++ how can that work?
Secondly, You can't use conio.h in sololearn so I replaced getch with getchar().
Thirdly, plz avoid lables and goto's in a program .It is bad way of writing program it may crash Ur program , It might be helpful in some emergency cases .
