Hey ,i'm a beginner and just start study C++ in few month. Why my coding wont run in CodeBlock but work in Dev C++. Your help would we very appreciated :)

#include <iostream>
using namespace std;
int kira(int,int);

int main()

{
int l,w;

cout<<"Enter length :";
cin>>l;

cout<<"Enter width :";
cin>>w;

cout<<"Area of rectangle is :"<<kira(l,w)<<endl;

system ("pause");
return 0;
}

int kira(int length , int width)

{
int area;

area=length*width;

return area;

}

system is not required to be defined by iostream.

I believe cstdlib is the header file you need for system.

Thanks firedraco. Now it worked.
I deleted => system ("pause"); .

Still wondering why it work after I deleted it , hurmmm.

ooh , and cstdlib doesn't work
