C# console application word recognition - visual-studio-2013

Question

It is necessary to create a program that will on the basis of input N car number plate ( eg . " KR 635 B " ) to count the number of vehicles from individual places . At the end of the program to print the amount of vehicles coming from a particular place , and the number of vehicles whose region is not recognized . Places that recognizes :
KR - Karlovac
BJ Bjelovar ...
I need a piece of code that identifies the first part of plate lets say: " KR " , because when I use if ( input = " KR " );
then recognizes only if I enter " KR " and not the entire registration .

Answer 1

You can use the StartsWith method to check the beginning of a string. Example:
if (plate.StartsWith("KR")) {
...
}
If you are checking for muliple vales, you might want to get that part of the string as a separate string. You can get the first two characters:
string region = plate.Substring(0, 2);
Or the characters up to the first space:
string region = plate.Substring(0, plate.IndexOf(' '));

Answer 2

bool again = true;
//variable
int bje = 0;
int zgr = 0;
int spt = 0;
int vzn = 0;
int npo = 0;
//petlja za y/n
while(again)
{
// program unutar loopa
Console.WriteLine("Unesite registarsku oznaku: ");
string unos = Console.ReadLine();
if (unos == "bj")
//
bje++;
else if (unos == "zg")
//
zgr++;
else if (unos == "sp")
//
spt++;
else if (unos == "vz")
//
vzn++;
else
npo++;
Console.WriteLine("Bjelovar: " + bje);
Console.WriteLine("zagreb: " + zgr);
Console.WriteLine("split: " + spt);
Console.WriteLine("varazdin: " + vzn);
Console.WriteLine("Nepoznato: " + npo);
// za ponovan unos loop
Console.WriteLine();
Console.WriteLine("Ponovni unos? (Da/Ne)");
string YN = Console.ReadLine();
while (YN != "Y" && YN != "N" )
{
Console.WriteLine("Wrong entry. Again? (Y/N)");
YN = Console.ReadLine();
}
if (YN == "n")
{
again = false;
}
}
See i need those "if statments" changed for that word recognition and just done that is under the if statment.
