Can someone guide me? I need to reverse text and don't have much leeway with changing code. Any suggestions?

std::mutex myMutex;
bool locked = true;

{

{
printf("ClassTwo Constructor\n");
}

~ClassTwo()
{
printf("ClassTwo Destructor\n");
}

void Function()
{
printf("ClassTwo Function\n");
}
};

void InMemoryReverse(char* buffer, int length)
{
for (int index = 0; index < length; ++index)
{
auto temp = buffer[index];
buffer[index] = buffer[length - index];
buffer[length - index] = temp;

void Multithreaded(int count)

printf("Multi-threaded: %d", count);

int main(int argc, char* argv[])
{
//- InMemoryReverse
printf("--- InMemoryReverse ---\n");
char reversibleText[] = "This text should be reversed.";
InMemoryReverse(reversibleText, strlen(reversibleText));

printf("InMemoryReverse: %s\n", reversibleText);

//- Object Oriented
printf("--- Object Oriented ---\n");
ClassOne one;
one.Function();

//- Multi-threaded
