What happens when you attempt to compile and run the following code?
#include
#include
#include
using namespace std;
template
int calculate(T start, T end)
{
int s = 0;
while (start != end)
s+= *start; start++;return s;
}
int main ()
{
int t[] = {1, 2 ,3 ,4 ,5, 6 , 7, 8 , 9, 10};
vector
deque
cout<<calculate(t,t+10)<<" ";
cout<<calculate(v1.begin()+1,v1.end()?2)<<" ";
cout<<calculate(d1.rbegin()+1,d1.rend()?2)<<" ";
cout<<calculate(t[0],t[10])<<" ";
cout<<endl;
return 0;
}
