Here is my code.
(Goal) I want to ask a series of questions. The first is asking for a name, if the user inputs the name ‘William’ I want the program to proceed to ask for their birthdate. If that is answered correctly I want it to ask a series of yes or no questions. If the name ‘William’ is not entered, I want the program to re-ask for the users name until it is correct so it can proceed.

My issue is that every time I enter the name ‘William’ it will feed me back this response…
(put below my code)

#include <stdio.h>
#include <string.h>

int main()
{
        char correctName[] = "William"; //This is the name that William will need to enter
        char correctBirthday[] = "(01/01/2000)"; //This is the correct birthday he will need to enter

        //The '100' represents how many character can be allowed in each questions answer
        char name[100];
        char birthday[100];
        char response[10];

        while (1) {
        printf("Hello, please enter your name: ");
        scanf("%s", name);

        if (strcmp(name, correctName) == 0) {
                printf("Thank you.n");
                break;
        } else {
                printf("Searching... nnInvalid user. Please enter first and last name.nn");
        }
        }

        while (1) {
                printf("I must ask you to confirm your birthdate with me so I can assure that it is you.n");
                printf("Please do so in this format: (MM/DD/YYYY). n");
                scanf("%s", birthday);

        if (strcmp(birthday, correctBirthday) != 0) {
                break;
        } else {
                printf("Searching... nn");
                printf("Invalid input. Only William is authorized to proceed. n");
         }
        }

        printf("Hello William!nn");

        printf("Do you wish to proceed? (yes/no): nn");
        scanf("%s", response);

        if (strcmp(response, "yes") == 0) {
                printf("Great! lets get started.n");
        }
         else {
        printf("Confirmed, have a nice day.n");
        }
    return 0;
}

//This is what I see when I input ‘William’

Hello, please enter your name: William

Invalid user. Please enter first and last name.

Hello, please enter your name: Searching…

Invalid user. Please enter first and last name.

Hello, please enter your name:

Ive tried rearranging the text and am quite a noob in the coding space right now so I am actively trying to learn as I go. I believe the birthdate text may be backwards but my first priority is to see that text in the first place. Thank you in advance!
