Given a string str and a character ch, this article tells about how to append this character ch to this string str at the end. Use the strncat() function to append the character ch at the end of str. strncat() is a predefined function used for string handling.
Approach: Get the character array and its size. Declare a string (i.e, an object of the string class) and while doing so give the character array as its parameter for its constructor. Use the syntax: string string_name(character_array_name);
Can you display a single character as a value? Select an answer: Yes, by changing the printf() function's placeholder from %c to %d.
All of
std::string s(1, c); std::cout << s << std::endl;
and
std::cout << std::string(1, c) << std::endl;
and
std::string s; s.push_back(c); std::cout << s << std::endl;
worked for me.
I honestly thought that the casting method would work fine. Since it doesn't you can try stringstream. An example is below:
#include <sstream>
#include <string>
std::stringstream ss;
std::string target;
char mychar = 'a';
ss << mychar;
ss >> target;
This solution will work regardless of the number of char variables you have:
char c1 = 'z';
char c2 = 'w';
std::string s1{c1};
std::string s12{c1, c2};
