Question

INTRODUCTION:

Oil exploration is being conducted by drilling holes and blasting the ground with specific amounts of dynamite to generate seismic readings that can be interpreted. To obtain useful seismic readings, a specific ratio between the amount of dynamite and the depth of the hole is needed. The ideal powder charge to depth-of-hole ratio is 1:3. For blasting operations, each stick of dynamite will be 1.5 feet long and will weigh 6 pounds. Ideally, we would use the exact amount of powder specified; however, in reality, useful readings aren’t generated when part of a stick of dynamite protrudes above the hole. Therefore, we will compute the actual powder charge in 6-pound increments and use fewer sticks than necessary, if needed.

A sample hand calculation follows below:

Hole depth = 85 feet
Ideal powder-to-hole depth ratio = 85/3 = 23.333333 feet
Ideal number of sticks = 28.333333/1.5 = 18.888888
Ideal powder charge = 18.888888*6 = 113.333333 pounds
Actual number of sticks = floor(18.888888) = 18

Actual charge = 18*6 = 108 pounds

An input data file called explore contains exploration information for each well site. The first record line of the input file is the control number, which defines the number of sites to be read into the program. Each succeeding record line has two columns, where the first column is the well site number and the second column is the hole depth of the well in feet. The input file is comma delimited.

ASSIGNMENT:

Write a C program that will read the required values from the input file into two one-dimensional arrays: one array for the well site number and one array for the hole depth. Using the hole depth array, compute the ideal powder-to-hole depth ratio, the ideal number of sticks, the ideal powder charge, the actual powder charge, and the actual number of sticks. Your program will produce a table as the report. Print the table to the computer screen and to an output file called blasting.

Once the program is working, modify the program to account for any hole depth that is less than 30 feet. Instead of printing the normal column items, for any hole that is less than 30 feet in depth, print the well site number, the well depth, and then print a message that the hole is too shallow.

Use the “Code Sections.c” template on Blackboard to write your code.

Your program output will look like the illustration shown below. Use your PC’s cursor to determine the horizontal and vertical spacing for the output format.
