C++ 10.19 Given a line of text as input, output the number of characters excluding spaces, periods, exclamation points, or commas. Ex: If the input is: Listen, Mr. Jones, calm down. the output is: 21 Note: Account for all characters that aren't spaces, periods, exclamation points, or commas (Ex: "r", "2", "?"). code provided: #include <iostream>#include <string>using namespace std; int main() { string userText; // Add more variables as needed getline(cin, userText); // Gets entire line, including spaces. /* Type your code here. */ return 0;}
1.11.2: Outputting all combinations. Use C++ Output all combinations of character variables a, b, and c, in the order shown below. If a = 'x', b = 'y', and c = 'z', then the output is:xyz xzy yxz yzx zxy zyxYour code will be tested in three different programs, with a, b, c assigned with 'x', 'y', 'z', then with '#', '$', '%', then with '1', '2', '3'. #include <iostream>using namespace std; int main() { char a; char b; char c; cin >> a; cin >> b; cin >> c; a = 'x'; b = 'y'; c = 'z'; cout << a << b << c << a << c << b << b << a << c << b << c << a << c << a << b << c << b << a; cout << endl; return 0;}
6.23 LAB - Flip a coin Define a function named CoinFlip that returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls function CoinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Output the total number of 'Heads' and 'Tails' Hint: Use the modulo operator (%) to limit the random integers to 0 and 1. Ex: If the random seed value is 2 and the input is: 3 the output is: Tails Heads Tails Total Heads: 1 Total Tails: 2 Note: For testing purposes, a pseudo-random number generator with a fixed seed value is used in the program. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used for each test case. The program must define and call the following function:string CoinFlip() Do Not Delete Any Existing…
6.26 LAB: Exact change - functions Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies. def exact_change(user_total) Use Python, please.

2.9.1 C++ The cost to ship a package is a flat fee of 75 cents plus 25 cents per pound.1. Declare a const named CENTS_PER_POUND and initialize with 25.2. Get the shipping weight from user input storing the weight into shipWeightPounds.3. Using FLAT_FEE_CENTS and CENTS_PER_POUND constants, assign shipCostCents with the cost of shipping a package weighing shipWeightPounds.
Let A={8,9,10}, B={9,10,11,12,15} and C={9,10}. Which of the following statements are true? a) d) {2,5} ⊆ A e) φ ⊆ C
Q 3) Write C# statements to accomplish each of following tasks: Assign the sum of x and y to w, and increment x by 1 with ++. Use only one statement and ensure that original value of x is used in statement. Test whether variable count is greater than 20. If it is, display “Count is greater than 20”. Decrement the variable x by 1, then subtract it from the variable total. Use only one statement. Calculate the remainder after q is divided by divisor, and assign the result to q. Write this statement in two different ways.
d. Given that an int variable s has been initialized, write a statement(s) that declares a new variable andassign it the remainder of 9 times 8 less than s divided by 4. e. Write a statement(s) that initializes the variables named a, b, c and d to false, ''one'', 'y' and 87.9respectively
21.7 LAB: Login name (Use python) Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: JordaM91 Ex: If the input is: Kanye West 2024 the output is: Your login name: WestK24
7. using c++, If c is a character (e.g. char c = ‘a’), then (int) c is a number between 0 and 255 that represents its ascii value of that character (the ascii value of ‘a’ is 97. Appendix B contains the ascii character set; for example, (int) ‘a’ == 97. Write a function that accepts two characters, c1, and c2, determines whether (int) c1 is greater than (int) c2, and then returns the sum of the ascii values of all the characters between c1 and c2.
Write C++ statements that accomplish the following. (6, 7)a. Declare int variables x and y. Initialize x to 25 and y to 18.b.

Declare and initialize a double variable payRate to 12.50.e. Copy the value of an int variable firstNum into an int variable temp Num.f. Swap the contents of the int variables x and y. (Declare additional variables, if necessary.)g. Suppose x and y are double variables. Output the contents of x, y, and the expression x + 12 / y - 18.h. Declare a char variable grade and set the value of grade to 'A'.i. Declare int variables to store four integers.j. Copy the value of a double variable z to the nearest integer into an int variable x.
