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:

  1. calories = int(input("Enter number of calories: "))
  2. fats = int(input("Enter number of fat in grams: "))
  3. if(calories > 0 and fats > 0):
  4.    cf = fats * 9
  5.    if(cf < calories):
  6.        percent = cf / calories  
  7.        if(percent < 0.3):
  8.            print("Food is low in fat")
  9.    else:
  10.        print("Error input. Calories from fat cannot more than total calories")
  11. else:
  12.    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)

A computer has a cache and main memory. 20 ns are required to reference a word that is in the cache. If the word is in main memo
Alecsey [184]

Answer:

T_{average} =12026ns

Explanation:

Given Information:

T_{cache}=20 ns

T_{main}=60ns

T_{disk} =12ms=12,000,000ns

hit_{cache} =0.9

miss_{cache} =1-0.9=0.10

hit_{main} =0.99

miss_{main} =1-0.99=0.01

There are 3 possible cases

1. Location of reference word is in cache

T_{cache}*hit_{cache} =20*0.9=18ns

2. Location of reference word is not in cache but in main memory

(T_{cache}+T_{main})*(miss_{cache}*hit_{main}) =(20+60)*(0.10*0.99)=7.92ns

3. Location of reference word is neither in cache nor in main memory

(T_{cache}+T_{main}+T_{disk})*(miss_{cache}*miss_{main})

(20+60+12,000,000)*(0.10*0.01)=12000.08 ns

The average time required to access a referenced word on this system is simply the sum of above 3 cases

T_{average} =18+7.92+12000.08=12026ns
