Passing by reference...or by value....

Basically im still learning about the two but im trying to do something. basically i have 2 files. in the first i have

int taco;
someFunctionCall(taco);

Then in the someFunctionCall i have

void someFunctionCall(int a)
{
     do math and conversions and etc here
}

and i need to set that variable a to the int taco above, reason being is that i need to have function calls but I cannot return anything, if I could return this would be alot easier thanks for any info!

Why can't you return? Typically, an out parameter would be used because some other value is already being returned, or it is expensive to copy. Neither of these apply here.

Use pointers.
Make your function accept the pointer and when calling, pass the address.

void foo (int* x)
{
    *x +=1;
}
//call 
foo(& int_var);

well cannot return because it is my assignment to not do it that way ^^, in terms of my assignment its pretty trivial i just must have missed when he mentioned how to do it =/. he talked about it like it was a pretty common thing in C to change the value of some variable in a different class. but i don't know
