Please help me, I am trying to create an expression creator that prints the work out too, not just the answer.
Code:

#include <iostream>
#include <windows.h>
using namespace std;
void p1();
void p2();
void p3();
double P,P2,p,ans,ans2,ans1,restart;
char V;
int Pick,Pick2,Pick3,Parts;
int main()
{
while(restart!=2){
cout<<"How many steps are in this equation? (1 or 2)\n> ";
cin>>Parts;
switch(Parts){
case 1:
p1();
break;
case 2:
p2();
break;
case 3:
///p3();
break;}
cout<<"\n\nRestart?\n1) Yes\n2) No\n> ";
cin>>restart;
system("cls");
}}
