Variadic templates allow you to create functions or classes that accept a variable number of template parameters. They enable more flexible and generic code. Variadic templates are useful for creating functions that work with different numbers of arguments.
Example of variadic templates:
#include
template
void print(T arg) {
std::cout << arg << std::endl;
}
template
void print(T arg, Args... args) {
std::cout << arg << " ";
print(args...);
}
int main() {
print(1, 2, 3.5, "hello");
return 0;
}
