Go over chaos program

# File: chaos.py
# A simple program illustrating chaotic behavior.
def main():
     print("This program illustrates a chaotic function")
     x = eval(input("Enter a number between 0 and 1: "))
     for i in range(10):
         x = 3.9 * x * (1 - x)
         print(x)
main()

Translation process. Text to Binary

In Python the program is interpreted. It is translated to binary by the Python language system and then run.

# program to print Hello, World!
def main():
     print("Hello, World!")

main()

In Java the program is translated to an intermediate format called bytecodes. These are interpreted or executed by a Java Virtual Machine.

In C++ the program is compiled for a specific computer system.

#include      // class for stream input/output
using namespace std;    // use the standard namespace

int main ()             //start of main function
{

      // Write 'Hello, World!'  to output

      cout << "Hello,  World! " << endl;

}

Translated to binary or octal (base eight) so it looks like

042577 043114 000401 000001 000000 000000 000000 000000
