Strings, File I/O You are free to use a single or multiple files for this project. If you are putting all functions in a single file, make sure that more abstract functions are defined first. Text justification is spacing of the text block so that both right and left side of the text have a straight edge. This is accomplished by adding spaces so that every line is exactly the same length. You are to implement simplified justification rules as follows. Every line should be exactly 75 characters long (keep this value in a named constant). To get to this line length, extra space is first added after punctuation marks. You need to consider only these marks: .!?; That is, every punctuation mark may be followed by two spaces. If the spaces after punctuation marks are added and the line is still less than 75 characters, additional spaces are added after random words in the line. There is no need to ensure that the extra spaces are spread uniformly. Randomization is sufficient. A line that is shorter than 40 characters is considered the end of a paragraph is not justified. Hyphenation (breaking up of words) between lines is not required. 1. Line Justification. Study code folding in MSVS described here. As you work on the below project, demonstrate to the lab instructor code folding and unfolding. Createa project titled Lab7_LineJustify. Write a program that asks the user to input a string and then prints this string out in 75 characters according to the above justification rules. You may assume that the user always inputs the line that is less than 75 characters. Below is an example dialog: input line: Contrary to popular belief, Lorem Ipsum is not simply random text your 1ine justified: Contrary to popular belief, Lorem Ipsum is not simply random text Hints: Use getline function to get user input. See this example for its operation. To locate spaces and punctuation characters, consider this code. This code demonstrates how multiple occurrences of the same symbol may be found. String size) function determines the number of characters in a string. This code demonstrates string modification. To rand omly insert spaces, consider the following approach loop until the string is the right size locate the end of the next word obtain a random boolean value (conditional operator is useful here) if true insert space locate the beginning of the next word, if end of the string is reached, start from the begining of the string Use find first_of (white space characters) to locate end of next word, and find first not_of (white space characters) to locate the beginning of the next word #include #include using std: :cout; using std::cin; using std::endl; using std: :string; // prints statistics of staring void print stats(const string &); int main(){ string s; // string to measure the parameters o:f string guit="". // guit after this comparison? cout #include using std: :cout; using std: :endl; using std::cin; using std::string; void printresult (int); // printing result of search int main()f string quit="y". // quit after this loop? cout tosearch; cout > tofind; cout > quit; \while (quit !-"y"); void printresult (int result) if(result != string ::npos ) cout #include iostream using std: :cout; using std: :endl; using std::cin; using std: :string; int main()f string s- "baa baa black sheep"; int pos-s.find('a'); while (pos-string: :npos){ cout #include
