Answer:

An if statement

Explanation:

Conditional statements are important aspects of programming where decisions are made depending on the outcome of one or more conditions.

Generally, the conditional statements are called selection control structure but because of the general syntax which it operates on, they are regarded as if statement.

There's no limit to the number of if statement a program can have.

The syntax of an if statement goes thus:

if(condition 1) {

statements

}

else if(condition 2)

{

statements

}

.....

....

else

{

statement

}

An example is a c++ program segment that compares and prints the larger number between two variables

if(x > y)

{

cout<<x<<" is greater than "<<y;

}

else if (y>x)

{

cout<<y<<" is greater than "<<x;

}

else

{

cout<<"Both numbers are equal";

}

In this exercise, your function will receive 2 parameters, the name of a text file, and a list of strings. The function will wri

diamong [38]

Answer:

# the function is defined

# it takes 2 arguments: filename and list of string

def solution(filename, listOfString):

# the file is opened in write mode

# so that we can write to it

with open(filename, 'w') as file_object:

# we loop through the entire list of string

# this looping help us know what to write to the file

for each_string in listOfString:

# if the length of the string is less than 4

# we write 'x' with a new line

if len(each_string) < 4:

file_object.write("x\n")

# else if the length of the string is greater than equals 4

# we write the fourth character

# and also add new line

else:

file_object.write(each_string[3])

file_object.write("\n")

Explanation:

The function is written in Python. It takes two argument; filename and list of string.

It opens the file in write mode and then loop through the list of string. During the loop, we know what to write to the file.

In the length of a string is less than 4; we write 'x' else we write the fourth character in the string. The fourth character has an index of 3 because string uses zero index counting like a string. Starting from zero; 0, 1, 2, 3, 4... the fourth character has an index of 3.

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.
