a big problem

can any1 tell me wut's the problem of this code:
#include <iostream.h>
int main()
{
int choice;
cout<<"Please choose: \n";
cout<<"1.ID program\n";
cout<<"2.2nd program\n";
cout<<"3.Quit\n";
cout<<" I Choose:";
cin>>choice;
if(choice==1)
{

cout<<"ok lets start!\n";
cout<<"Welcome to shady's first c++ program\n";
cout<<"wut's ur name?\n";
char name[50],action[50];
cin.getline (name, sizeof (name));
cout<<"Welcome "<<name <<"\n";
cout<<"wut do u wanna do? \n";
cin.getline (action, sizeof (action));
cout<<"no u can't "<<action <<"\n";
}

if(choice==2)
{
cout<<"ok lets start!\n";
cout<<"Welcome to shady's second c++ program\n";
char name[90];
cout<<"wut's ur name?\n";
cin.getline(name, sizeof (name));
cout<<"wut's your gender? \n";
char gender[90];
cin.getline(gender, sizeof (gender));
cout<<"wut's ur birthdate?\n";
char birthdate[90];
cin.getline(birthdate, sizeof (birthdate));
cout<<"Your name: "<<name <<"\n";
cout<<"Your gender: "<<gender <<"\n";
cout<<"Your birthdate: "<<birthdate <<"\n";
}
if (choice==3)
{
cout<<"Byebye";
}
else
{
cout<<"This is not an option";
}
return 0;
}

1st, use code tags and indent. makes code easier to read.

2nd, use endl at the end of your cout statements, it flushes the buffer and causes a "\n" internally.

3rd, your ifs on 2 and 3 should be "else if"

4th, don't you want to loop and do the menu again if you aren't choosing 3?

You will also need to add cin.ignore() after cin>>choice. It will get rid of the return at the end of the string, so your first getline in the IF (whichever is executed) won't be empty.

What exactly are you having problems with?
