Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times

otez555 [7]

Answer:

The program written in python is as follows

def countchr(phrase, char):

count = 0

for i in range(len(phrase)):

if phrase[i] == char:

count = count + 1

return count

phrase = input("Enter a Phrase: ")

char = input("Enter a character: ")

print("Occurence: ",countchr(phrase,char))

Explanation:

To answer this question, I made use of function

This line defines function countchr

def countchr(phrase, char):

This line initializes count to 0

count = 0

This line iterates through each character of input phrase

for i in range(len(phrase)):

This line checks if current character equals input character

if phrase[i] == char:

The count variable is incremented, if the above condition is true

count = count + 1

The total number of occurrence is returned using this line

return count

The main method starts here; This line prompts user for phrase

phrase = input("Enter a Phrase: ")

This line prompts user for a character

char = input("Enter a character: ")

This line prints the number of occurrence of the input charcater in the input phrase

print("Occurence: ",countchr(phrase,char))

Write a program that prompts the user to enter 50 integers and stores them in an array. The program then determines and outputs

Marrrta [24]

Answer:

Here is code in C++.

#include <bits/stdc++.h>

using namespace std;

int main()

{

int n=50;

// integer array to store 50 integers

int arr[n];

cout << "Enter 50 integers: ";

//read 50 integers into array

for (int i = 0; i < n; i++)

cin >> arr[i];

cout << endl;

//sort the array

sort(arr,arr+n);

// find all the pairs which give sum equal to any element of the array

for (int i = 0; i < n; i++)

{

cout<<"pair which give sum equal to ";

cout << arr[i] <<" is :";

for (int j = 0; j < n; j++)

for (int k = j + 1; k < n; k++)

if (arr[i] == arr[j] + arr[k])

cout <<"("<<arr[j]<<" & "<< arr[k] <<")"<<",";

cout << endl;

cout << "*******************************" << endl;;

}

return 0;

}

Explanation:

Read 50 integers into an array from user.Sort the array in ascending order.Travers the sorted array and find all pairs which give sum of equal to any element of the array.Then print all such pairs.

Output:

Enter 50 integers: 23 30 34 1 3 4 9 12 96 92 80 84 123 54 67 87 34 55 21 38 29 111 10 44 103 47 83 72 77 88 80 56 49 5 102 166 134 200 205 188 178 133 154 148 162 191 193 207 209 44

pair which give sum equal to 1 is : *******************************

pair which give sum equal to 3 is : *******************************

pair which give sum equal to 4 is :(1 & 3), ******************************

pair which give sum equal to 5 is :(1 & 4), ******************************

pair which give sum equal to 9 is :(4 & 5), *******************************

pair which give sum equal to 10 is :(1 & 9), *******************************

pair which give sum equal to 12 is :(3 & 9), *******************************

pair which give sum equal to 21 is :(9 & 12), *******************************

pair which give sum equal to 23 is : *******************************

pair which give sum equal to 29 is : *******************************

pair which give sum equal to 30 is :(1 & 29),(9 & 21), *******************************

pair which give sum equal to 34 is :(4 & 30),(5 & 29), *******************************

pair which give sum equal to 38 is :(4 & 34),(4 & 34),(9 & 29),

ABC incorporated wants to implement a TCP/IP network for its only site. It has 180 employees and two buildings and requires Inte

riadik2000 [5.3K]

Answer:

A private IP address should be implemented but a PAT and a static NAT should be configured for the computers and the intermediate devices respectively.

Explanation:

There are two types of IP addresses, they are public and private addresses. The public address is an IP4 address routable on the internet while the private address is not routable.

Internet service providers do charge for the use of public IP addresses they render, which can be very costly. To reduce the company's expenses on the internet, the company is networked with private addresses and are mapped for network address translation ( NAT) which assigns a public global address to devices accessing the internet.

What is the output of 1101 x 10 == 11000 + 10?

Marta_Voda [28]

== is an operator that returns a boolean if both operand are equal.

1101 * 10 is 11010

11000 + 10 is 11010

11010 == 11010

Thus the output would be True.
