Why the usage of pointers in C++ is not recommended ?
write a program that reads in a file and counts the number of lines, words, and characters. Your program should ask the user to input a filename. Open the file and report an error if the file does not exist or cannot be opened for some other reason. Then read in the contents of the file and count the number of lines, words, and characters in the file. Also print additional information about the file, such as the longest and shortest words, and longest and shortest lines. For simplicity, we define a word to be one or more characters ending with white space (a space, tab, carriage return, etc.). Functions for checking the types of characters can be found in the ctype.h header file, so you want to include this header file in your program. For example, the sentence below could be all that is in a file. This sentence IT 104 is taught in C++. has 32 characters, one line, and six words. The shortest line is 32 characters. The longest line is 32 characters. The shortest word is 2 characters. The longest word is 6 characters
