append to stringc++ code example

Example 1: append string to another string c++

// appending to string
#include <iostream>
#include <string>

int main ()
{
  // easy way
  std::string str = "Hello";
  std::string str2 = " World";
  std::cout << str + str2 << std::endl;
  return 0;
}

Example 2: appending string in c++

#include<iostream>
#include <string>
int main() {
	//"Ever thing inside these double quotes becomes const char array"
//	std::string namee = "Caleb" +"Hello";//This will give error because adding const char array to const char array 
	std::string namee = "Caleb";
	namee += " Hello";//This will work because adding a ptr to a actual string
	std::cout << namee << std::endl;// output=>Caleb Hello
//You can also use the below
	std::string namee2 = std::string("Caleb")+" Hello";// This will work because constructor will convert const char array  to string, adding a ptr to string
	std::cout << namee2 << std::endl;// output=>Caleb Hello
	std::cin.get();
}
