Question

Programming C++ Language, PLEASE HELP, Will upvote

Write a program that first generates two random decimal numbers within the range -100 to 100 inclusive. Next, generate a random number between 1 and 4 inclusive to correspond to each of our math operators (+, -, *, /). Finally, write out to a file called mathWorksheet.txt the following format:

A o B = ?

With A and B replaced by the two random numbers that were generated and o replaced by the random math operator. A complete example is shown below:

-15.15 * 82.311 = ?
