Script 3 - C/C++ Template File Maker I often complain that I need to make a script or a macro to setup the skeleton of a C/C++ code file for me since I get tired of typing it every single time. Create a script named code TemplateMaker.sh that takes a -c or -cpp and creates a C or C++ template file. Syntax: ./codeTemplateMaker.sh Use Case: ./codeTemplateMaker.sh -c Output: #include #include int main(int argc, char** argv) { } Use Case: ./codeTemplateMaker.sh -cpp Output: #include #include using namespace std; //TODO: Code goes here return 0; int main(int argc, char** argv) { } Use Case: Output: //TODO: Main code. return 0; ./codeTemplateMaker.sh usage: ./codeTemplateMaker.sh [-cl-cpp]
python function that creates and saves data in a file. the saved data represents exam grades. in the function , you will create n random numbers in the range 1-100, where n is the number of students. The function can be called as follows: createFile(filename, n) main function, in which the user inputs the file name and the number of students, then the main calls function createfile. the main should preform validation for n (should be > 0), and the filename(should end with .txt)

Description (for python please) This is a command line program, dl_cu.py that accepts two parameters: a root directory a best before date in the form YYYY-MM-DD Based on these inputs dl_cu.py generates a report lists all of the files thathaven't been modified since the best before date. The output includes: The full path of each file The modification date of the file The file file size in MB After presenting the user with this list it will ask them if they would like todelete all of of the listed files and any empty directories stored in the root directory.
This part of the quiz will contain 4 parts. A function called grade, a function called pgrade, a prototype file called grade.h and a main function.
