Here are two text files, whose names are given by two string variables, file1 and file2. these text files have the same number of lines. write a sequence of statements that creates a new file whose name consists concatenating the names of the two text files (with a "-" in the middle) and whose contents of merging the lines of the two files. thus, in the new file, the first line is the first line from the first file, the second line is the first line from the second file. the third line in the new file is the second line in the first file and the fourth line is the second line from the second file, and so on. when finished, make sure that the data written to the new file has been flushed from its buffer and that any system resources used during the course of running your code have been released. (do not concern yourself with any possible exceptions here—assume they are handled elsewhere.)

When creating a presentation in libre office impress, where does the editing of slides take place?

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
