while statement

I have typed up a program to have a loop to let the user do a math function or enter a name function. I want this loop to be continuios untill the user exits the program. I did not put the code in to exit the program because I am more concern about the loop working. Here is the code that I have typed up:

#include <iostream.h>

int info();
void doMath();
void enterName();

int main()
{
int x;
x=info();
cin.ignore();
while(x==1)
{
doMath();
x=info();
cin.ignore();
}
while(x==2)
{
enterName();
x=info();
cin.ignore();
}
return 0;
}

int info()
{
char y;
cin.ignore();
cout << "\nPress M to do the math" << "\nPress N to enter the name";
cout << "\nWhat would you like to do? ";
y=cin.get();
if(y == 'M' || y == 'm')
return 1;
if(y == 'N' || y == 'n')
return 2;
else
return 0;
}


void doMath()
{
int hour,wage,pay;
cout << "\nEnter the hours worked";
cin >> hour;
cout << "\nEnter the wage";
cin >> wage;
pay = hour*wage;
cout << "\nThe pay is " << pay;
}

void enterName()
{
char name[10];
cout << "\nEnter the name";
cin.getline(name,20);
cin.ignore();
cout << "\nYou entered: " << name;
}

When I run the program it will not let me enter my choice of doing the math or entering the name

Try this!!!

// while.cpp
#include <iostream.h>
#include <cctype>
using namespace std;

// user function
char info();
void doMath();
void enterName();

int main()
{
char sign;
sign = toupper(info());
while (sign == 'M' || sign == 'N')
{
cin.clear();
cin.get();
switch (sign)
{
case 'M': doMath();
case 'N': enterName();
}
sign = toupper(info());
}
cout << "Bye bye.\n";
return 0;
}

char info()
{
char y;
cout << "\nPress M to do the math" << "\nPress N to enter the name";
cout << "\nWhat would you like to do? ";
cin >> y;
return y;
}
void doMath()
{
int hour,wage,pay;
cout << "\nEnter the hours worked: ";
cin >> hour;
cout << "Enter the wage: ";
cin >> wage;
pay = hour * wage;
cout << "The pay is " << pay << "\n";
}
void enterName()
{
char name[50];
cout << "\nEnter the name: ";
cin.getline(name,50);
cout << "You entered: " << name << "\n";
}

if it doesn't work, mail me : URL
