Is there any problem in below code?

#include <string>
#include <iostream>

void println_cstr(const char *text){
    std::cout<<text<<std::endl;
}

void println_string(const std::string &text){
    std::cout<<text<<std::endl;
}

int main(int argc, char **argv){
    const char *s_cstr = "This is a C string";
    std::string s_cpp("This is a C++ string");
    println_cstr(s_cpp);
    println_string(s_cstr);
    return 0;
}
