I'm writing a programming language in C++ and I need to append a char to an std::string.
I've read some other posts on Stack Oferflow about this issue, but none of them solved mine. The first thing I tried was something like this:
#include <iostream>
#include<string>
int main() {
std::string str;
char ch;
str = "Hello";
ch = '!';
str = str + ch;
}
but G++ said that I can't concatenate a string with a character because of the different types. G++ error:
no operator "+" matches these operands
On Stack Overflow I read that I can use the .append() method, but the compiler didn't even recognize this method saying
no instance of overloaded function "std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::append [with _CharT=char, _Traits=std::char_traits<char>, _Alloc=std::allocator<char>]" matches the argument list
Can someone help me?
you have many methods. Some here:
#include <iostream>
#include <string>
int main()
{
std::string str = "Hello";
str.push_back('!');
std::cout << str << std::endl;
str += '@';
std::cout << str << std::endl;
str = str + '*';
std::cout << str << std::endl;
str.append(1, '#');
std::cout << str << std::endl;
str.insert(str.size(), 1, 'o');
std::cout << str << std::endl;
}
