Other What does 9"*"9 in coding mean

What does the character "*" mean in coding?

Like when I use it like this 9*9.

It multiplies the numbers.

 

In C++ it also doubles as "dereference operator", in case you want to have a pointer to some variable or object. Pointers allow function to modify the variable passed, instead of being limited to doing stuff with a copy of the original variable (thus not touching the real thing). Here's an example:

Code:

void someFunc(int* x) {
    *x += 10; // modify the variable in the address passed to the function
}

int main() {
    int x = 10;
    std::cout << x << std::endl; // will print '10'
    someFunc(&x); // pass the address of variable 'x' to the function
    std::cout << x << std::endl; // will print '20'
    return 0;
}

but you know... if you're doing Lua the only thing this operator does is multiply the numbers. Here's a practical example:

Code:

local halfWidth = ScrW() * 0.5 -- multiplies your screen's width by 0.5, basically dividing it by 2. Could also be written as ScrW() / 2

 

wtf nerds

 

It ....Eat your fucking fast food FATTY.

so 9*9 = 81?

 

Yes.

 

and how I calculate

.9*SCREENxSCREEN or a canvas?
