Question
please I really need a help with this question. please don't answer if your answer does nothing with mine.Write a C++ program, which prints number of lines,words and characters from an input text file. We define a word as number of character devided by one or more a white spaces.
A white space is contains one of the following newline, carriage return, tab or space (' ', ' ', ' ', ' '),
A character is any character includin white space.
The program shall promt the user for the name of input and output file.
The program writes the result to the screen and to the output file in the
following way:
The input contains:
xx lines
yy words
zz characters
Observe:
1) Devide the program in to subtasks.
2) Implement each suptask as a function. The main program is mostly
function calls. .
3) Write comments in the code.
