This problem requires you to write three lines of related code. 1. Declare a file pointer. (A short name is just fine.) 2. Using your file pointer from Part1, write one line of code to open a file named f.dat that will have input data. (NO error checking required) 3. Write ONE line of code to read data from the file you just opened above in Part 2. Use double variables c and d. Use of a while is optional.
