Answer:
microcomputers are installed with TCP/IP protocols because its a set of standardized rule that allows the computer to communicate on a network such as the internet
Answer:
Following are the program in the Python Programming Language.
#declare variable and initialize to 0
sum = 0
#read the following file
file = open('numbers.txt', 'r')
#set the for loop
for n in file:
#convert the file string into the integer and perform sum.
sum += int(n)
Explanation:
<u>The following are the description of the program</u>.
- Firstly, declare variable 'sum' and initialize the integer type value i.e., 0.
- Set the variable 'file' that only read the following file text i.e., 'numbers.txt'.
- Set the for loop that read the content of the file and store in the variable 'n' one by one.
- Finally, er convert the following string in to the integer and perform the addition.
Answer:
The solution code is written in Java.
- public class Main {
- public static void main(String[] args) {
- System.out.print("Please enter a number: ");
- Scanner console = new Scanner(System.in);
- int n = console.nextInt();
- calculateSum1(n);
- calculateSum2(n);
- calculateSum3(n);
- calculateSum4(n);
- }
- public static void calculateSum1 (int num){
- int sum1 = 0;
- for(int i=1; i <= num; i++){
- sum1 += i*i*i;
- }
- System.out.println("Sum 1 : " + sum1);
- }
- public static void calculateSum2 (int num){
- int sum2 = num * num * (num + 1) * (num + 1) / 4;
- System.out.println("Sum 2 : " + sum2);
- }
- public static void calculateSum3 (int num){
- int sum3 = 0;
- for(int i=1; i <=num; i++){
- sum3 += i;
- }
- sum3 = sum3 * sum3;
- System.out.println("Sum 3 : " + sum3);
- }
- public static void calculateSum4 (int num){
- int sum4 = (num * (num + 1) * (2*num + 1)) / (4+2);
- System.out.println("Sum 4 : " + sum4);
- }
- }
Explanation:
Firstly we create four different methods that calculate the sum of the first n cubes in different ways (Line 13 - 43).
This is important to understand the concept of operator precedence to work out the different ways of summation.
For example, The operator * and / will always have higher precedence than +.
On another hand, any expression enclosed within the parenthesis will have highest precedence and therefore the value will be evaluated prior to others.
This is also important to understand the expression evaluation will always start from left to right.
The program is an illustration of functions; functions are used to represent collection of named statements
<h3>The program in Python</h3>
The function in Python where comments are used to explain each line is as follows:
#This defines the function
def checkList(nums,num):
#This checks if num exists in nums
if num in nums:
#If yes, this returns the index of num
return nums.index(num)
#If otherwise, this returns -1
return -1
