New to c++! please help with loop!?

[gierkej]

I need to make this program go back to entering your name when you hit "n" or "N", but continue if you hit "y" or "Y"
Help please??


#include <iostream>
#include <string>
#include <cmath>
#include <cstdlib>

using namespace std;

int main()
{

char name[20];

cout <<"Enter your name:" << endl;
cin.getline(name, 20);
cout <<"\nYou have chosen the name: " << name << endl;

cout <<"\nIs this correct?\n<Y/N>\n" << endl;

char yn;
cin >> yn;


if (yn == 'y' || yn == 'Y')
cout <<"\nThen let's move on...\n" << endl;//continue program if user enters "Y or y"

else if (yn == 'n' || yn == 'N')
cout <<"\nWell then, what is it?\n" << endl;//loop back to start if user enters "N" or "n"


system("pause");
return 0;
}

Use a while or do-while loop:

Code: Select all


do
{
   string name; //strings are better because they are not size limited. U'll need to include <string>
   cout <<"Enter your name > ";
   cin>>name; //Now you are not limited to 20 characters
 
   cout <<"\nYou have chosen the name: " << name << endl;
   cout <<"\nIs this correct?\n<Y/N>\n" << endl;

   char yn;
   cin >> yn;
   
   if (yn == 'N' || yn == 'n')
      cout<<"\nOK, let's try again"<<endl;
   else
      cout<<"Thank you"<<endl;
}
while (yn == 'N' || yn == 'n');

Also, please use [code] [/code] or [syntax="cpp"] [/syntax] around your code to keep it readable.
