Thread: I need help in coding using void function

I don't know how to code the receipt part of this program. Please help me. I'm a beginner.

Code:

#include <stdio.h>
#include <stdlib.h>


void MenuDisplay(void);
void Order(void);
void receipt(void);


void MenuDisplay(void){
    printf("\t\t\t\t      Restaurant Name");
    printf("\n\n\t\t\t\t           MENU");
    printf("\n\t[1] Grilled Cheese\t80php\t [11] Squash Soup\t60php");
    printf("\n\t[2] Apple Cider Chicken\t120php\t [12] Vegetarian Chili\t100php");
    printf("\n\t[3] Steamed Green Beans\t95php\t [13] Ratatouille Salad\t110php");
    printf("\n\t[4] BBQ Pulled Pork\t130php\t [14] Bacon Frittata\t100php");
    printf("\n\t[5] Shrimp Pasta\t125php\t [15] Spicy Chicken\t130php");
    printf("\n\t[6] Bacon Swiss Burger\t110php\t [16] Rosemary Chicken\t140php");
    printf("\n\t[7] Chicken Parmesan\t120php\t [17] Smoked Salmon\t140php");
    printf("\n\t[8] Beef Lasagna\t90php\t [18] Tortilla Wrap\t80php");
    printf("\n\t[9] Mixed Green Salad\t85php\t [19] Braised Beef\t120php");
    printf("\n\t[10] Salmon Teriyaki\t150php\t [20] Beef Pot Roast\t160php\n\n");
    }
