Hi The struct that u are using is basically a templated struct and when u are
calling static function you have to mention the template arguments.But why?
Actually when we are using templates there is no such thing as sum<T>.all
these templates change to the required classes (that were used in the code) and
only that generated classes are then added to the obj file.the error free code
looks like
#include <iostream>
#include <conio.h>
using namespace std;
template <class T> void foo(T op1, T op2) {
std::cout << "op1 = " << op1 << std::endl;
std::cout << "op2 = " << op2 << std::endl;
}
template <class T>
struct sum {
static void foo(T op1, T op2)
{
std::cout << "sum = " << op2 << std::endl;
}
};
int main()
{
foo(1,3);
foo<int>(1,' 3');
sum<int>::foo(1,2) ; // Error in this line and corrected through providing
argument for call
getch();
return 0;
}
