    I'm a beginner C++ programmer, and to me your explanation is just perfect. Thanks!

    Nice one yet again, Kevin. Appreciate the clarity and of course as always, the utter lack of fluff. 👍

    I cannot get the range-based for loop to work with my on-heap array. How come?

      This stackoverflow answer coves this issue and has a workaround too: stackoverflow.com/a/15919834. :-)

    Thanks once again for everything! char my_array [] - here my_array is essentially a pointer to the first character - so when we declare a string using a pointer directly - char* my _array = "Portfolio"; - why am I getting this error -
    Error (active) E0144 a value of type "const char *" cannot be used to initialize an entity of type "char *' - I am also not able to modify individual characters in a string after declaring the string because of the read only permission. Thanks!

      This video may answer some of your questions regarding char * vs char [] and storing strings: th-cam.com/video/Qp3WatLL_Hc/w-d-xo.html. It looks like you may run into issues trying to use strings stored this way with range-based for loops, the recommendation seems to be to use it to create a proper string in C++: stackoverflow.com/questions/18020517/using-range-based-for-loops-with-char-pointer-string.

    hi, is it possible to print a int* which is pointing to 3 elements using Range Based For Loop?

      I think you could do it using a technique like in this answer: stackoverflow.com/a/64199190. :-)

    how do if i want to print the indexes of the array?, example : cars indexes of 1, ship indexes of 2 etc

      Great question! :-) You could use a variable like this answer here on Stackoverflow: stackoverflow.com/a/15149476. Or instead of a range-based for loop you could use a regular for loop instead with a counter variable i that keeps track of the index in the array: th-cam.com/video/8CdKMqW4LC4/w-d-xo.html. If you want the array index, then a range based for loop probably isn't the best approach, I would suggest using a regular for loop instead.
