C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of UNIX-based operating systems are written in C.
C is a general purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system. It was named 'C' because many of its features were derived from an earlier language called 'B'.
It depends what you need... there is new string('a',3)
for example.
For working with strings; you could just loop... not very interesting, but it'll work.
With 3.5, you could use Enumerable.Repeat("a",3)
, but this gives you a sequence of strings, not a compound string.
If you are going to use this a lot, you could use a bespoke C# 3.0 extension method:
static void Main()
{
string foo = "foo";
string bar = foo.Repeat(3);
}
// stuff this bit away in some class library somewhere...
static string Repeat(this string value, int count)
{
if (count < 0) throw new ArgumentOutOfRangeException("count");
if (string.IsNullOrEmpty(value)) return value; // GIGO
if (count == 0) return "";
StringBuilder sb = new StringBuilder(value.Length * count);
for (int i = 0; i < count; i++)
{
sb.Append(value);
}
return sb.ToString();
}
If you only need to repeat a single character (as in your example) then this will work:
Console.WriteLine(new string('a', 3))
