// Problem 1: Let the user provide you any number, and you must determine if
// the number is even or odd. If even, print the number is "EVEN!", if odd, 
// print the number is "ODD!"
// Steps to solve it: 
// 1. Take the input in from the user: scanf()
// 2. To check even, % 2 = 0
// 3. If that is TRUE, then printf "EVEN"
// 4. If that is FALSE, then printf "ODD"



// Problem 2: Let the user provide you a number 1-100, that you check and decide
// how many digits the number has.

// PROBLEM 1:
#include <stdio.h>

int main(void){

    // Declared a variable number of type int
    int number;
    // Initialise it by scanning into it (taking the user input)
    printf("Enter a number: ");
    
    // scanf() returns the number of things that were scanned in
    // successfully 
    // Declare a variable to hold whatever it is that scanf returns
    int scanf_return;
    scanf_return = scanf("%d", &number);
    printf("The value of scanf_return is %d\n", scanf_return);

    if (number % 2 == 0){
        printf("EVEN!\n");
    } else {
        printf("ODD!\n");
    }

    return 0;
