Question

/I was given the basic outline of the program from my teacher and we were told to do all the functions. I have already done all the functions but im having trouble getting them into the outline correctly. Heres the outline and all the functions all i need is help copy and pasting it all together so it runs. It is very possible that there may be a small error in the functions. I need this program to be running smoothly. any help will be much appriciated.

#include <iostream>
#include <iomanip>

using namespace std;

/ Function Prototypes /

string Menu();
int getValue( string, int, int );
void doAverage();
double calcAverage( int, int );
void doFactorial();
int calcFactorial( int );
void doMtoNth();
int calcMtoNth( int, int );
void doRange();
int calcRange( int, int, int, int );
int main()
{
string userChoice;

userChoice = Menu();

while ( userChoice != "Q" && userChoice != "q" )
{
if (userChoice == "1")
{
doAverage();
}
else if ( userChoice == "2" )
{
doFactorial();

Explanation / Answer

hey i dont have exact solution but hope this below code help you definatly

#include<iostream.h>

#include<conio.h>

int main()

{

int choice, num, i ;

unsigned long int fact;

clrscr();

while (1)

{

cout<<"1. Factorial ";

cout<<"2. Prime ";

cout<<"3. Odd / Even ";

cout<<"4. Exit ";

cout<<" Your choice ?";

cin>>choice ;

switch ( choice)

{

case 1 :

cout<<" Enter number:";

cin>>num ;

fact = 1 ;

for (i=1 ;i<=num ;i++)

fact = fact * i;

cout<<"' Factorial value = "<< fact;

break ;

case 2 :

cout<<"' Enter number:";

cin>>num ;

for(i=2;i<num;i++ )

{

if (num%i== 0 )

{

cout<<" Not a prime number. ";

break ;

}

}

if (i==num)

cout<<"' Prime number. ";

break;

case 3 :

cout<<" Enter number:";

cin>>num ;

if ( num %2==0 )

cout<<"' Even number. ";

else

cout<<" Odd number. ";

break;

case 4 :

return 0;

}

}

getch();

}
