Intellisense: expected a ';'

[Donny]

I can't see where though. I've listed where the red line comes up where the error is, but I can't see the problem.

could it be because your void randomnumber() [line 29]

attempts to return a value of RN? I'm a noob @ c++ but I thought void functions could not return values?

[anonymous23323124]

That is probably it, yes. Intellisense expects a semicolon immediately after return as the void function cannot return a value.

[Donny]

Well the function is called randomnumber()

i've declared RN (meaning random number) as an integer.

and I return RN, which will either be 0 or 1.


I think anyway, i've only been doing c++ around 6 month in my first year at university and it isn't one of my strengths.

[Donny]

I've tried that Xander but still to no avail.

[anonymous23323124]

If you want a function to return a value, you must tell the compiler this in your function header:

void func(); // returns nothing
int func2(); // returns integer
float func3(); // returns floating point number
bool func4(); // returns boolean
// etc 

Your random number function is declared as void:
void randomnumber();

If you want to learn more about functions, see here

Also, you can't define functions inside of main. Changevoid randomnumber() to int randomnumber() and add a } on line 27
