Question

Need help fixing these two programs, I'm really new to c++ so the little things are hard to find

#include <iostream>
using namespace std;

int main()
{
int a;

cout << "The area of a triangle with base 1 and height 5 is "
<< << endl;

area = (4+3)/2;
cout << "The area of a triangle with base 4 and height 3 is"
<< area << '.';

cout << 'The area of a triangle with base 3 and height 6 is '
<< area << '.';

return 0;
}
