Write a program to sort the (name, age, score) tuples by descending order where name is string, age and score are numbers. The s

zimovet [89]

Answer:

The program in Python is as follows:

from operator import itemgetter

m = int(input("Number of records: "))

print("Name, Age, Score")

my_list =[]

for i in range(m):

user_details = input()

my_list.append(tuple((user_details.split(","))))

my_list.sort(key = itemgetter(0, 1, 2))

print("Sorted: ", my_list)

Explanation:

This imports the operator function from itemgetter

from operator import itemgetter

This gets the number of records, m

m = int(input("Number of records: "))

This prints the format of input

print("Name, Age, Score")

This initializes the list of tuples

my_list =[]

This iterates through m

for i in range(m):

This gets the details of each person

user_details = input()

This appends the details to the tuple

my_list.append(tuple((user_details.split(","))))

This sorts the tuple

my_list.sort(key = itemgetter(0, 1, 2))

This prints the sorted tuple

print("Sorted: ", my_list)

Write a program that accepts three decimal numbers as input and outputs their sum

Sophie [7]

Answer:

sum = 0.0

for i in range(0,3):

sum += float(input("Enter a decimal number to sum: "))

print ("Sum: ", sum)

*** Sample Input ***

Enter a decimal number to sum: 1.1

Enter a decimal number to sum: 2.2

Enter a decimal number to sum: 3.3

*** Sample Output ***

Sum: 6.6

Explanation:

For this problem, a method was devised in python to create the sum of three individual decimal numbers.

The first line of code, sum = 0.0, initializes a variable to the float type in which we will store the value of our sum. Note, it is initialized to 0.0 to start from a value of 0 and be considered a float.

The second line of code, for i in range(0,3): is the creation of a for loop control structure. This will allow us to repeat a process 3 amount of times using the iterator i, from value 0 to 3 in this case. Note, 0 is inclusive and 3 is exclusive in the python range. This means the for loop will iterate with, i=0, i=1, and i=2.

The third line of code, sum += float(input("Enter a decimal number to sum: ")) is simply asking the user for a number, taking that input and converting it from a string into a float, and then summing the value with the previous value of sum and saving that into sum.

The fourth line of code, print ("Sum: ", sum) is simply displaying the final value that was calculated by adding the three user inputs together which were stored into the variable sum.

Cheers.

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in

Zina [86]

Answer:

Here is the C++ program:

#include <iostream> // to include input output functions

using namespace std; // to identify objects like cin cout

int counter(string userString, char character) { //function counter

int count = 0; // counts the no of times a character appears in the string

for (int i=0;i<userString.length();i++)

// loop to move through the string to find the occurrence of the character

if (userString[i] == character) //if characters is found in the string

count++; //counts the occurrence of the character in the string

return count; } //returns the no of times character occurs in the string

int main() { //start of the main() function body

string s; // stores the string entered by the user

cout<<"Enter a string: "; //prompts user to enter the string

cin>>s; //reads the string from user

char ch; //stores the character entered by the user

cout<<"Enter a character: "; //prompts user to enter a character

cin>>ch; //reads the character from user

cout << counter(s, ch) << endl; }

//calls counter function to find the number of times a character occurs in the //string

Explanation:

The counter function works as following:

It has a count variable which stores the number of occurrences of a character in the userString.

It uses a for loop which loops through the entire string.

It has i position variable which starts with the first character of the string and checks if the first character of userString matches with the required character.

If it matches the character then count variable counts the first occurrence of the character and in the userString and is incremented to 1.

If the character does not match with the first character of the userString then the loops keeps traversing through the userString until the end of the userString is reached which is specified by the length() function which returns the length of the string.

After the loop ends the return count statement is used to return the number of occurrences of the character in the userString.

The main() function prompts the user to enter a string and a character. It then calls counter() function passing string s and character ch arguments to it in order to get the number of times ch appears in s.

The output is attached in a screenshot.
