// Week 3 Monday Lecture
// Demonstrations of writing and using functions with different prototypes
// It is good style to have prototypes at the top, in the order
// they are used in the program. 
// Then have the actual implementations below main.

#include <stdio.h>

// Function prototypes
int maximum(int x, int y);
void print_stars(int number_of_stars);
void print_warning(void);

int main(void) {
    int num = 7;
    // Store the return value in a variable to use later 
    int max = maximum(10, num);
    print_stars(max); 
    print_warning(); 
    return 0; 
}

// Given two integer inputs, x and y, 
// returns the larger of the two integers
int maximum(int x, int y) {
    int max = x;
    if (x < y) {
        max = y;
    }
    // returns an int value 
    return max;
}

// Given an int input, prints the specified number of stars
// on a single line
void print_stars(int number_of_stars) {
    int i = 0;
    while (i < number_of_stars) {
        printf("*");
        i = i + 1;
    }
    printf("\n");
}

// Prints a warning message
void print_warning(void) {
    printf("#########################\n");
    printf("Warning: Don't plagiarise\n");
    printf("#########################\n");
}
