Object-oriented Programming in C#
Introduction to C#
Input and output

Input and output (IO) is handled by a number of different classes in C#. In both C and C# there very few traces of IO in the languages as such.

Output to the screen and input from the keyboard is handled by the C# Console class

File IO is handled by various Stream classes in C#

  • Similarities

    • Console.Write and Console.WriteLine in C# correspond to printf in C

  • Differences

    • There is no direct counterpart to C's scanf in C#

    • Comprehensive formatting support of DateTime objects in C#
