Computer programming is important today because so much of our world is automated. Humans need to be able to control the interaction between people and machines. Since computers and machines are able to do things so efficiently and accurately, we use computer programming to harness that computing power.

Consider the following program segment. ifstream inFile; //Line 1 int x, y; //Line 2 ... //Line 3 inFile >> x >> y;

MrMuchimi

Answer:

inFile.open("progdata.dat");

Explanation:

This command opens the file which is passed to it as an argument. We are quite used to the C++'s cin and cout functions contained in iostream library for reading and writing data, however, when working will real-life stuff, we find ourselves working with huge data saved as separate files and require our programs to read them, manipulate them and possibly write back to the files... The first operation usually carried out before a file can be read or written to is open

For this lab you will do 2 things:

zepelin [54]

Answer:

Here is the Python program:

COOKIES_PER_BAG = 40 #sets constant value for bag of cookies

SERVINGS_PER_BAG = 10 #sets constant value for serving in bag

CALORIES_PER_SERVING = 300 #sets constant value servings per bag

cookies = int(input("How many cookies did you eat? ")) #prompts user to input how many cookies he or she ate

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG)); #computes total calories consumed by user

print("Total calories consumed:",totalCalories) #displays the computed value of totalCalories consumed

Explanation:

The algorithm is:

Start
Declare constants COOKIES_PER_BAG, SERVINGS_PER_BAG and CALORIES_PER_SERVING
Set COOKIES_PER_BAG to 40
Set SERVINGS_PER_BAG to 10
Set CALORIES_PER_SERVING to 300
Input cookies
Calculate totalCalories: totalCalories ← cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG))
Display totalCalories

I will explain the program with an example:

Lets say user enters 5 as cookies he or she ate so

cookies = 5

Now total calories are computed as:

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG));

This becomes:

totalCalories = 5 * (300/40/10)

totalCalories = 5 * (300/4)

totalCalories = 5 * 75

totalCalories = 375

The screenshot of program along with its output is attached.
