Ok, again we are talking about c + +, this time we continue with the operator in c + +. The most important part of a program. For those of you a physicist, knowledge of the operators is important in making a program, it also applies even if you're a game maker. We gave a list of frequently used operators. Actually there are many operators, you may not see it here, but maybe in the next tutorial you will find it.
One that you have noticed, some operators read from left to right, some others read from right to left. For example operators: assignment, conditional, type casting, Increase, Decrease, bit inversion, boolean inverse; works by reading from right to left. For practice, try the code below by using c++ software.
Probably, it is good to add the following explanation.
ReplyDeleteThe differentiate between n++ and ++n (and also n-- and --n):
n++ will return the value of n first, then increments itself by 1, e.g:
int n = 8;
cout << n++ << endl;
cout << n << endl;
will print:
8
9
but ++n will do the opposite. it will increment itself by 1 first, then return the value.
int n = 8;
cout << ++n << endl;
cout << n << endl;
will print:
9
9
For Muhammad Alvin:
DeleteThank you for your share. When we want to create this post I want to do that. But if we do that at this post then I broken our rules. One of them is give step by step for each tutorial. In the next time we will try to give more clearly again. Thank you Alvin
