Intellisense: expected a ';'

Donny (8)
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 (1383)
That is probably it, yes. Intellisense expects a semicolon immediately after return as the void function cannot return a value.
Donny (8)
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 (8)
I've tried that Xander but still to no avail.
anonymous23323124 (1383)
If you want a function to return a value, you must tell the compiler this in your function header:
1
2
3
4
5
 
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();

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