Hi, Geo,
I would like use the second way. Because it can protect the fields (or
elements) of the "random" from being changed in the function.
Do you know the differences from these two ways:
int i;
1) function(i);
2) function(&i);
And you can write a piece of codes to check it .
I am a "rookie". If you find any mistake in what I said, pls let me know.
