![A picture of code.
This code reads:
#include <string>
#include <cstring>
#include <cstdio>
#define length(array) ((sizeof(array)) / (sizeof(array[0])))
template <char... format>
std::string greet_internal(const std::string& n)
{
std::string result;
const char format_string[] = { format... };
result.resize(n.size() + length(format_string) - 2);
sprintf(
const_cast<char *>(result.c_str()),
format_string,
n.c_str());
return result;
}
std::string greet(const std::string& n){
return greet_internal<'H', 'e', 'l', 'l', 'o',',',' ','%','s',' ','h','o','w',' ','a','r','e',' ','y','o','u',' ','d','o','i','n','g',' ','t','o','d','a','y','?'>(n);

![A screenshot of code. This is a coding problem from codewars.
The problem to solve is:
Make a function that will return a greeting statement that uses an input; your program should return, "Hello, <name> how are you doing today?".
[Make sure you type the exact thing I wrote or the program may not execute properly]
The solution given is:
std::string greet(const std::string& n){
std::string result;
std::string format_string= "Hello, %s how are you doing today?";
result.resize(n.size() + format_string.size() - 2);
sprintf(
const_cast<char *>(result.c_str()),
format_string.c_str(),
n.c_str());
std::cout << result << std::endl;
return result;
