1. Learning about Programming Languages
By:
Mike and Sean

2. Goals -Discuss the following languages
-C, Java, Python, Scheme, Assembly
-Identify the strengths and weaknesses of the languages.
-Describe brief history for each language.
-Give easy, medium, and advanced examples of a program for each language.

3. Plan Learn the basic concepts of the languages
Learn what all the languages have in common
See what aspects of the languages differ Ex
Arrays are different among the languages
Functions differ between languages (Java uses methods, Python and Scheme uses procedures)

4. Ex. “Hello World” Python print “Hello World!” Scheme (begin
Java
class HelloWorldApp{
public static void main(String[] args) {
System.out.println(“Hello World!); C
#include<stdio.h>
int main() {
printf(“Hello World!”);
return 0; }
Python
print “Hello World!”
Scheme
(begin
(display “Hello, World!”)
(newline))

5. Concepts Aspects all programming languages share:
Booleans – Primitive data type have one of two values: True or False
Loops – Series of commands repeated until condition becomes false.
Condition – A Boolean expression used to control loops.
Comments – Notes in the program for programmers, not shown in program.
Nesting – Putting one thing inside something else, such as a nested loop.
