1- Write a program that asks the user to enter 3 numbers than displays the following menu:
c- Display the numbers sorted in decreasing order
d- Display odd numbers
e- Display even numbers
f- Write the numbers in a file.
The program then asks the user to enter his choice and executes the required task.
If the user enters option ‘f’ ,the program will have to ask the user to enter the name of the file.
Important :
1- Use a switch to handle the different options of the menu.
2- All numbers need to be displayed with 2 decimals precision.

#include <iostream> #include <fstream> using namespace std;
void bubbleSort(); int arrayofnumbers[3]; int main() { char ch=' '; for(int i=0;i<3;i++){ printf("Enter number %d: ",i+1); scanf("%d",&arrayofnumbers[i]); } do{ printf(" c - Display the numbers sorted in decreasing order "); printf("d - Display odd numbers "); printf("e - Display even numbers "); printf("f - Write the numbers in a file. "); printf("q - Exit "); printf("Select one item: "); ch=getchar(); ch=getchar(); switch(ch){ case 'c': bubbleSort(); printf("The numbers sorted in decreasing order: "); for(int i=2;i>=0;i--){ printf("%d,",arrayofnumbers[i]); } break; case 'd': printf("Odd numbers: "); for(int i=0;i<3;i++){ if(arrayofnumbers[i]%2==1){ printf("%d,",arrayofnumbers[i]); } } break; case 'e':
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
