In C++ you can create an array of strings:
string myArray[10];
(Note that value 10 is a NULL character, and the first value is 0)

As for declaring it, you could use a for loop to count through and get the user to enter them all:
cpp
for (int i = 0; i < 10; i++)
    cin >> myArray[i];

Or, you could define them seperately:
cpp
myArray[0] = "danny";
myArray[1] = "leonardo";

Or, you could define them all on the same line:
cpp
string myArray[10] = {"danny", "leonardo", etc...);

The Dev C++ compiler says C:\Documents and Settings\maqsoodrehman\My Documents\arr.cpp `string' undeclared (first use this function) .
Can you help me with this. What i want to do is to store 10 names from the console i.e. want to prompt the user for 10 names and store them in a for loop.
Please help.

OK, it's compiler specific stuff: some will include string as a standard, others you have to add #include <string> to the top of your code. Try it out and see if it works now happy.gif

Now my requirement is to sort 10 names from their with respect to their first character using bubble sort or any other sorting algorithm. I have my code here:

#include <iostream.h>
#include <conio.h>
#include <string.h>



main()
{
char name[10][25];


cout<<"Enter the Names:"<<endl;


//prompt user to input 10 names
for (int i = 0; i<=9; i++)
{
cout<<"Name"<<i+1<<": ";
cin>>name[i];
}



//display 10 names
for (int j=0;j<=9;j++)
{
cout<<name[j]<<endl;
}

getch();
}

How can i sort the names stored in name[i] with respect to their first charater.[size=3][size=3]
Please help
