Lexicographical order, assignment help
1-
Write the program that asks the user to enter 10 names of cities (one name at a time) to be stored in an array, sorts the resulting list of city names lexicographically and displays the sorted list to the console.
Note: Lexicographical order is a generalization of the way the alphabetical order of words is based on the alphabetical order of their component letters. It is also known as dictionary order.
Hint: Comparing two words lexicographically can be done by using “<” and “>” for C++ strings.
Example:
Original List: Paris, Washington DC, London, Tokyo, Madrid, Rio di Janeiro, Brussels, Ankara, Rome, Amsterdam
After applying the Lexicographical order, the list will be become:
Resulting List:Amsterdam, Ankara, Brussels, London, Madrid, Paris, Rio di Janeiro, Rome, Tokyo, Washington DC
If the first letters of the two cities are the same, you should compare the next ones.
Original List:Ankara, Amsterdam
Resulting List:Amsterdam, Ankara

You are given the following source code to search for a number in an array
#include <iostream>
using namespace std;
int search(int sa, int list[ ], int size)
{
bool notFound = true;
int position = -1;
int k = 0;
while (k<size && notFound)
{
if (list[k] == sa)
{ notFound = false;
position = k;
}
k++;
}
return position;
}
int main( )
{
int searchArg = 17;
int myList[10] = {16,14,54,23,8,12,17,36,11,22};
int pos;
// call Search to find the value’s position
pos = search(17,myList,10);
cout << “Search key was found at index “ << pos << endl;
Modify search function and the main method to search for a string value, entered by the user,in a string array, instead of searching for an integer value in an integer array.
This is the string list to use for test:
List: Rome, Ankara, Brussels, London, Madrid, Paris, Rio di Janeiro, Tokyo, Washington DC
