c++ add values in string code example

Example 1: c++ insert variable into string

#include <iostream>

using namespace std;

int main()
{
  string someString = " C++ "
    
  cout << "This is a" + someString + "example." << 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();
}
