Compiler Error C2780

  • Artikkeli

'declaration' : expects N arguments - M provided

A function template has too few or too many arguments.

The following sample generates C2780 and shows how to fix it:

// C2780.cpp
template<typename T>
void f(T, T){}

int main() {
   f(1);  // C2780
   // try the following line instead
   // f(1,2);
}
