Thread: help with password uppercase

Hi guys!

Im creating a program where i want the user to type a password with atleast one uppercase letter! The code is working when i type uppercase letter only on the beginning for example "Banana" . But when i type uppercase letter in the middle " baNana" it isnt working.
Help plz?

Code:

 
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>
int main()
{
    char a[10];
    int i;
    printf("Enter your password: ");
    for (i=0;i<10;i++)
    {
        scanf("%s",&a[i]);
        if (!isupper(a[i]))
        {
            printf("\nYour password must contain atleast 1 uppercase");
        }
        else { printf("\nPassword Good!"); }
    }
 
    return 0;
}

You have to decide whether to use %c or %s specifier for scanf and write little additional logic to decide if more than one upper case is occurring. You have to take care of the limits of for loop and size of array a.

You need to choose whether you want to read and verify one character at a time, and act accordingly - in that case you shouldn't use scanf with the %s specifier (actually you shouldn't use scanf with %s at all imo), OR read the whole input to a buffer and then verify, depending on what logic you are looking for.
