Hello there! I am playing around at random for now before continuing reading the litterature that I am using to learn C.

What is a less “ugly” way to break out the while loop at the last if-else statement than leaving else empty? I guess I could have avoided this if I knew how to terminate the program at the switch - case (E) other that break -ing out of it as I am now, in other words, not having to “climb” out of switch , then while and then reaching “Goodbye!”.

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

//Save "pins" in an array with an upper limit of ten pins. "Saved pins" resets if the upper limit is reached.  
int main(void) {  

	int pin = 0;  
	int check = 0;  

	//Saved pins  
	int pin_history[10]={0,0,0,0,0,0,0,0,0,0};  
	int pin_history_index = 0;  
	int pin_history_limit = 10;  

	int choice = 0;  

	printf("Enter your new pin: ");  
	scanf("%d", &pin);  
	getchar();  
	printf("Confirm your new pin: ");  
	while ((scanf("%d", &check))) {  
		if (check != pin) {  
			getchar();  
			printf("\nMismatch! Confirm your new pin: ");  
		}  
		else if (check == pin) {  
			pin_history[pin_history_index] = pin;  
			pin_history_index = pin_history_index + 1;  
			if (pin_history_index >= pin_history_limit) pin_history_index = 0;  
			printf("\nYour new pin has been saved successfully!\n");  
			break;  
		}  
	}  

	printf("What would you like to do next?\n\n(V)iew your saved pins\n(S)ave another pin\n(E)xit\n");  
	while ((choice = getchar()) != EOF) {
