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
```

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#.
