+//This is the basics of cpp
+
+//This is the inbuilt header file which exactly means 'input output stream'.
+//It takes care of the functions such as cin, cout etc, which is used to take input and print output
+#include<iostream> 
+
+using namespace std;
+//“using namespace std” means we use the namespace named std. “std” is an abbreviation for standard. 
+//If we don’t want to use this line of code, we can use the things in this namespace like this. std::cout, std::endl.
+//If this namespace is not used, then computer finds for the cout, cin and endl etc.. Computer cannot identify those and therefore it throws errors.
+
+//int main is our driver function, which is the main function called whenever a cpp file is executed
+int main() {
+    cout << "Hello World!"; //If we have hadn't written 'using namespace std', our statement would have been
+    //std::cout << "Hello World!";
+    return 0; 
+    //'int' in int main means we have to return an integer value
