1) Program to read three numbers and display them in descending order.

  

#include <iostream>
using namespace std;

int main() {
   // your code goes here
   int input_array[3],index;
   for(int i=0;i<3;i++)
cin>>input_array[i];
   for(int i=0;i<3;i++){
   for(int j=i;j<3;j++){
   if(input_array[i]<input_array[j]){
   int temp=input_array[j];
   input_array[j]=input_array[i];
   input_array[i]=temp;
   }
   }
   cout<<input_array[i];
  
  
   }
   return 0;
}

output:

2) program to display the menu

#include <iostream>
using namespace std;

int main() {
   // your code goes here
int input;
cout<< "select a menu\n";
cout<<"1. food 2. drink\n";
   cin>>input;
   if(input==1){
   cout<<"you have selected food. Which food?\n";
   cout<<"1. Korean 2. American 3.Chinese\n";
   cin>>input;
   if(input==1)
   {
   cout<<"you have selected Korean food. Which Korean food?\n";
   cout<< "1. Rice 2. Bulgogi\n";
   cin>>input;
   if(input==1)
   cout<<" enjoy your Rice!";
   else
   cout<<"enjoy your Bulgogi!";
   }
   else if(input==2){
   cout<<"you have selected American food. Which American food?\n";
cout<<"1. Hamburger 2.Salad \n";
cin>> input;
if(input==1)
cout<<"Enjoy your Hamburger!";
