Prompt the user to input there name then output there name in reverse order.

Why hello thar.

Code: Select all

#include <iostream>
using namespace std;

int main(){
   char line[100];
   for (int y = 0; y <= 99; y++)
      line[y] = '%';
   cout << "Enter a line of text up to 100 characters. End it with a percent sign (%).\n";
   cin.getline(line, 100, '%');
   cout << "Here is your line: ";
   cout << line << endl;
   cout << "Now here is your line in reverse: ";
   for (int x = 99; x >= 0; x--)
   {
      if (line[x] != '%')
         cout << line[x];
   }
   cout << endl;
   system("PAUSE");
   return 0;
}


Works with any line of text up to 100 chars. May increase the max later.
*EDIT* Had to change last line of code so it would work as an independent .exe file without Visual Studio.

Here's mine

Code: Select all

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string name;
    cout << "Enter your name: ";
    getline(cin,name);
    cout << "\nHere is your name in reverse: ";
    int i = name.length();
    while (i >= 0)
    {
        printf("%c", name[i]);
        i--;
    }
    cout << "\n\nHit any key to quit.\n\n";
    cin.ignore();
    return 0;
}


heres mine

Code: Select all

#include <iostream>

using namespace std;

int main()
{
    string name;

    cout << "please enter your name" << endl;
    cin >> name;

    for (int i = name.size();i >= 0;i--)
    {
        cout << name[i];
    }
   
}



Hmm now that i have seen how others have done this im not sure if what i did is right ^^

It does the work dont look very pretty but it does the work, as long as your name is not longer then 10 letters

Code: Select all

#include "stdafx.h"
#include <iostream>

using namespace std;

int main(){

   cout<<"Hi what is your name?\n";
   cout<<"Type your name letter by letter after each letter press enter\n";
   cout<<"When your done press - and enter till you get your result\n";
   
   char a,b,c,d,e,f,g,h,i,j;

   cin>>a;
   cin>>b;
   cin>>c;
   cin>>d;
   cin>>e;
   cin>>f;
   cin>>g;
   cin>>h;
   cin>>i;
   cin>>j;

   cout<<a<<b<<c<<d<<e<<f<<g<<h<<i<<j;
   cout<<"Sounds for me like: ";
   cout<<j<<i<<h<<g<<f<<e<<d<<c<<b<<a<<endl;
   
system("PAUSE");
return 0;
}

But i must admit that i had not any knowlege of how to turn a string around or reverse it

Here's what I did:

Code: Select all

#include "stdafx.h"
#include <iostream>

using namespace std;

int main()
{
   cout <<"First Name: ";
   char name[10];
   cin >> name;
   for(int x = strlen(name); x >= 0; x--)
   {
      cout << name[x];
   }
      
   system("pause");
   return 0;
}


Here you go make it a little more challenging have it check if it's a palindrome
(words say the same thing both ways like racecar, or two words like straw warts) get the idea
