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();
}
