Simple Dungeon Crawl

This is my second project using c++, Dungeon Crawl. The aim of the game is to reach the treasure ‘X’ without touching a trap. I have diy-ed the game a little and increased the number of traps with each turn.

Using:

• variables, data types, and numerical operators
• basic input/output
• logic (if statements, switch statements)
• loops (for, while, do-while)
• arrays
• functions
