Write a program that asks for the number of calories and fat grams in a food. The program should display the percentage of calor

Zigmanuir [339]

Answer:

The solution code is written in Python 3:

calories = int(input("Enter number of calories: "))
fats = int(input("Enter number of fat in grams: "))
if(calories > 0 and fats > 0):
cf = fats * 9
if(cf < calories):
percent = cf / calories
if(percent < 0.3):
print("Food is low in fat")
else:
print("Error input. Calories from fat cannot more than total calories")
else:
print("Error input. Calories and fats must be more than 0")

Explanation:

Firstly, use input function to ask user to enter total number of calories and fat in grams (Line 1-2)

Next we do the first input validation to check if the calories and fats are more than 0 (Line 4). If so apply formula to calculate calories from fats. If not, print error input message (Line 5, 13)

Then we proceed to next input validation to check if calories from fact more than total calories. If so, proceed to calculate percentage of calories from fats and if it is lower than 30%, display the appropriate message (Line 6 - 9). If fail the second input validation, the program will display another error input message again (Line 11)

Explanation:

[NB: since it is very long there is the need for me to put it it a document form. Kindly check the doc. Files. The file A is the sort Analysis.Java file and the file B is the sort.Java file].

The concept of algorithm time measurement strictly depends on the following;

=> The measurement of time, space or energy on different sizes.

=> Plotting of the measurements and characterizing them.

=> Running or implementation of the algorithm.

Programming language such as Java can be used in accessing the operating system clock and Java had two static methods.

<h3>How to define an array in C++?</h3>

An Array is a set of values arranged in lists and accessible through a positive numeric index. So, we have that each position of our Array is a variable of the type of our Array, so we have to have a way to initialize this set of variables.

Write the definition of a function typing_speed, that receives two parameters. The first is the number of words that a person ha

Lera25 [3.4K]

Answer:

The definition of function is as follows:

def typing_speed(number_of_words,Time_Interval):

number_of_words>=0

Time_Interval>0

speed=float(60*number_of_words/Time_Interval)

return speed

Explanation:

Above function is defined step-by-step as follows:

def typing_speed(number_of_words,Time_Interval):

A function named typing speed has two arguments, num_of_words and Time_Interval.

number_of_words>=0

Time_Interval>0

The variable number_of_words is the number of words entered that a person enters, they must be greater than or equal to 0. Where as Time_Interval is the variable for counting the time span in seconds, it must be greater than 0.

speed=float(60*number_of_words/Time_Interval)

return speed

For determining result firstly the seconds are converted int minutes by multiplying with 60 and number_of_words is divided with Time_Interval in order to get words per minute. The return value will give speed which has data type float.
