Write a program in c++ that reads a string of at least 20 characters from an input file. The input file has several lines of such strings. If the string is less than 20 characters then print "line number ln# has # characters and is less than 20" eg. Line number 6 has 8 characters and is less than 20. For all other lines, divide the string into 2 equal parts and print the result in a different output file. For example input string is : This-class-is-for-summer-semester output : This-class-is-fo r-summer-semester Organize it so that you have functions to read a string, divide the string and then output the string,
