Code from lecture

Pointers

• Pointer declaration - difference/similarities with declaring basic types
• Accessing variables “indirectly” via pointers
• The address and indirection operators: “&” and “*”
• Pointers and arrays - similarities and dfferences
• Passing arrays to functions - specifically looking at how arrays degnerate to pointers on function calls.

Under the hood of function calls

• Function calls use the run-time stack, we’ll see how and why that’s important
• Review of pass by value
• Passing parameters to functions by address
