Indexof() explain this steps clearly....
void main()
{
string name;
name = Console.ReadLine();
string s1 = Console.ReadLine();
Console.WriteLine(text1.cou(name,s1));
}
class text1
{
public static int cou(string name,string no)
{
int i = 0,c=0;
while((i=name.IndexOf(no,i))!=-1) // Explain this loop ,how it work
{
i = i + no.Length;
c++;
}
return c;
}
}
