THANK YOU, FINALLY FOUND SOMEONE WHO EXPLAINS SIMPLE AND FAST.

Excellent video. Your explanation is clear. Thank you!

If I may add: The "&" sign is directly referring to the memory location of whatever variable follows the "&" sign. By doing so you change the value stored at that specific location in the computers memory.

thanx makes some sense now. if i understood it correctly, pass by value only reads the switch(girl) function when it is called in the main function or sentence, but pass by reference takes the switch(girl) function and applies it to the rest of the sentences where the variable in the switch(girl) function can be applied in the main function.

In pass by reference I don't think it changes the variable girl to the variable boy. I think it just changes the value of the variable but not the actual name.

it should be switch(&girl) even during the function call.

While I was barely grasping the concept as a novice programmer, my brain was constantly shouting NO! NO! NO! throughout the video...

retaliation for underrepresentation of women in the tech industry by force feminizing the boy in "the code"? Subtle.

No mention of the const qualifier on parameters and its side effects in suppressing the construction of temporary objects.

Would have been better with REAL code but if this were an interview I'd give her a pass on that.
