pahelp case study c++

[TABILIN]

If the value of the integer variable number is 2, square it. If it is 3, input a new value for number. If it is 4 or 5, multiply it by 3 and display the new value. Write the appropriate C++ code using the switch statement...pahelp po homework dipa dinidiscuss..pinapagawa na ng instructor namin.salamat po

sa php ganito sya:

$variable=must be 2,3,4,5 ang value;
switch($variable) {
  case 2:
    $newValue=2*2;
    break;
  case 3:
    $newValue="enter kahit anong value"; // dapat may function ka na magproprompt na text field para pwedeng mag input ng bagong value ng $variable. 
    break:
  case 4:
   $newValue=4*3;
   break;
  case 5:
   $newValue=5*3;
   break;
  default:
   $newValue=0;
  break;
}

echo $newVariable //kapag ididisplay mo na yung value.

Same procedure lang din yan sa C++ sa palagay ko.. hahaha.. palitan mo nalang yung mga variables, at yung kung paano mo ididisplay yung result.

<rant> anong appropriate C++? bket kelangan pa i C++ kasi ang ganyang mga task, kelangan bang gamitan pa ng inheritance at polymorphism para lang magawa yan?, mga prof talaga ngayon. </rant>

TS. Tingin ko gusto ng prof mo na mag-advanced reading kayo kaya nagbigay ng assignment yan.
Mas madali sana kung may sinimulan ka na

anyway, eto sample program in C++ ng switch statement.

#include <iostream>
using namespace std;

int main ()
{
// local variable declaration:
char grade = 'D';

switch(grade)
{
case 'A' :
cout << "Excellent!" << endl;
break;
case 'B' :
case 'C' :
cout << "Well done" << endl;
break;
case 'D' :
cout << "You passed" << endl;
break;
case 'F' :
cout << "Better try again" << endl;
break;
default :
cout << "Invalid grade" << endl;
}
cout << "Your grade is " << grade << endl;

return 0;
}

hindi pa kasi ako marunong mag syntax sa c++ kaya sa c lang muna
ito baka makatulong. . .
#include <stdio.h>

int main()
{
int num, new_value;

printf("Enter Value:");
scanf("%d",&num);
switch (num)
{
case 2:
new_value=2*2;
printf("\n New value is %d",new_value);
break;
case 3:
printf("\nInput new value");
break;
case 4:
new_value=num*3;
printf("\n New value is %d",new_value);
break;
case 5:
new_value=num*3;
printf("\n New value is %d",new_value);
break;
default:
{}
}
return 0;
}

switch(number){
case 2:
nw_number=number*number;
cout<< "new number is" << nw_number<< endl;
break;
case 3:
cout<< "Enter New Number"<<endl;
cin>> nw_number;
cout<<"new number is"<<nw_number<<endl;
break;
case 4:
case 5:
nw_number=number*3;
cout<<"new number is"<< nw_number<<endl;
break;
default:
cout<<"wrong input"<<endl; // optional
}

return 0;

case 4 and 5 trivial yun kaya to avoid redundancy , much better kung ganyan.. i know its too late pero hope ot helps..
