The following code compiles succesfully but the base function not calling.

#include <iostream>
 

void tprintf(const char* format)
{
    std::cout << "["<<format<<"]";
}
 
template<typename T, typename... Targs>
void tprintf(const char* format, T value, Targs... Fargs)
{
    for (; *format != ''; format++)
    {
        if (*format == '%')
        {
            std::cout << value;
            tprintf(format + 1, Fargs...);
            return;
        }
        std::cout << *format;
    }
}


int main() {
    tprintf("% world% %ShouldbeCalledFromBase", "Hello", '!', 123, 444);
}

I am expecting output as:

Hello world! 123[ShouldbeCalledFromBase]

But current output is:

Hello world! 123ShouldbeCalledFromBase

I just want to know why base function not calling.
