From an old email my friend sent me when I started learning to code

Suggested Study Order:

• loops ( for, while, do-while )
• arrays
• pseudo random number generation
• strings & string functions
• functions
• structures/classes
• enumerated data
• file input/output
• pointers
• sorting
• linked lists
• advanced classes
• recursion
