1) Given a file named execution. log write the necessary code to add the line "Program Execution Successful" to the end of the file. 2) Given an ofstream object named output , associate it with a file named yearsummary. txt by opening the file for appending.
3) Given the availability of an ifstream object named input, write the other statements necessary to read an integer into a variable datum that has already been declared from a file called rawdata. Assume that reading that one integer is the only operation you will carry out with this file.
4) Given an initialized variable fileName, write a sequence of statements that create a file whose name is given by the variable and whose content is a single line consisting of "This Is File: " followed by the name of the file. Make sure that the data written to the file has been flushed from its buffer and that any system resources used during the course of running these statements have been released.
5) Use an ifstream object named indata to read the first three integers from a file called lottowins and write each number to standard output, on a line by itself. Assume that this is the extent of the input that this program will do.
6) Given an int variable x write some statements that attempt to open a file named "table20" and read a value into x; if that turns out not to be possible your code should then read avalue from standard input into x.
7) Given the availability of a file named numbers write the statements necessary to read an integer from standard input and then read in that many values from numbers and display their total.
8) Given an fstream object named todo, associate it with a file named todolist by opening the file for appending.
