Code:

//Programming in C


#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
int temp;
float amount = 0,tax = 0.12;
float resolver_Func(int temp)
{
    switch(temp)
    {
    case 1:
        return 40;
        break;
    case 2:
        return 40;
        break;
    case 3:
        return 40;
        break;
    case 4:
        return 80;
        break;
    case 5:

    case 6:
        return 25;
        break;
    case 7:
        return 380;
        break;
    default:
        return 0;
        break;
    }


    exit(0);
}
void take_order(int opt)
{
    printf("\n\n");
    int i;
    for (i = 0; i < opt; i++)
    {
        printf("What's the %d dish number? ", (i+1));
        scanf("%d", &temp);
        amount += resolver_Func(temp);
    }
    amount += (amount*tax);
    printf("Final amount = %f", amount);
}
int main(void)
{
    float opt;
    system("cls");
    printf("FOOD DISH \t PRICE(Rs.)");


    printf("\n1.)Rajma Chawal \t 40");
