Study Notes
Skeletons
- Skeleton programs represent the simplest form of code that compiles successfully.
- Their primary function is to define the entry point of a program without executing any tasks.
- Memorization of skeletons is advisable for structured program development.
- Common structure includes BEGIN and END pairs, signifying the start and completion of program segments.
Skeleton Examples
- C# Skeleton:
-
using System; class MainClass { public static void Main (string[] args) { } }
-
- C++ Skeleton:
-
#include <iostream> int main () { return 0; }
-
- Java Skeleton:
-
class MainClass { public static void main (String[] args) { } }
-
- Python Skeleton:
-
if __name__ == "__main__": pass
-
- All skeletons must contain a 'main' function, marking the starting point of execution.
Printing to the Screen
- To display text, syntax varies by programming language but generally follows a structured approach:
- Pseudocode example:
-
BEGIN MAIN PRINTLINE “Hello, World!” PRINT “Bob” + “ was” + “ here” END MAIN
-
- Pseudocode example:
- C# Example:
-
using System; class MainClass { public static void Main (string[] args) { Console.WriteLine("Hello, World!"); Console.Write("Bob" + " was" + " here."); } }
-
- C++ Example:
-
#include <iostream> using namespace std; int main () { cout << "Hello, World!" << endl; cout << "Bob was here." << endl; return 0; }
-
- Different languages may have additional functions for printing, such as
Console.Write()
in C#.
