C ++将字符串[4]转换为字符串

Question

I want to change the last character of a word to be a string.

thanks!

EDIT: adding Jon's attempted answer as it provides some insight into what his functional requirement is:

string x = "apple"; char c = apple[4]; string q = "";
string z = q+c;

Answer 1

std::string x = "apple";
std::string z(x.substr(4, 1));

Answer 2

Could this work?

string x = "apple";
char c = apple[4];
string q = "";

string z = q+c;

Answer 3

If you got a char[] lets say char arr[] = "Lalelu THis is a for-worded word:P";

Then you could try:

std::string str; str.assign(&arr[strlen(arr)-5], 4);

Answer 4

try this..

std::string apple = "apple";
std::string fpp(apple.rbegin(), apple.rbegin() + 1);

Answer 5

Try something like this:

string MyString = "Whee!"; // String to extract letter from.

char LastChar = MyString.at(MyString.length() - 1); // Retrieves the last letter of the string and stores it as a char.
string LastCharAsString = string(1, LastChar); // Typecasts the char to a string.

Untested, as I don't have access to a compiler ATM.
