please code in pythonis_phone_num: This Boolean function takes a string and returns True if it is in the formatddd-ddd-dddd, where d is a digit, False otherwise. Example calls:is_phone_num('123-456-7890') --> Trueis_phone_num('123-4556-7890') --> Falseis_phone_num('(123)456-7890') --> False
C++ Fix this code so that it displays in the format like the image shown where the principal and rate should have a fixed precision of 2 for each of the five percentages 5%,6%,7%,8%,9%,10%. The amount of the deposit should not have the fixed precision and should remain in the decimal format. #include <iostream>#include <iomanip>#include <cmath>using namespace std; int main(){double principal{ 1000 };double rate{ 0.05 }; for (rate; rate <= 0.10; rate += 0.01) {cout << "" << endl;cout << "Initial principal: " << principal << endl;cout << "Interest Rate: " << rate * 100 << "%" << endl;cout << setw(4) << "Year" << setw(20) << "Amount on deposit" << endl;for (unsigned int year{ 1 }; year <= 10; year++) {double amount = principal * pow(1.0 + rate, year); cout << setw(4) << year << setw(20) << amount << endl; }}}
1.Write a program that will read in the names (multiple-word string, ie with blanks) and sales amounts (float) for 2 staff members. It will then print the values in the following format. Use gets() functions to read the string values. Use field modifiers to format the output, so that the field width for staff name is 20 and it is left-justified. The field width for sales amount is 12 with 2 decimal places. (Use C++ (stdio.h, printf...) to create the program.) Enter staff name > Ang Boon Ching Enter sales amount > 2500.00 Enter staff name > Tong Eng Fang Enter sales amount > 900.00 Staff Name Sales Amount ==================== ============ Ang Boon Ching 2500.00 Tong Eng Fang 900.00

Write a function, named randomPassword, that generates a random password that takes noparameter. It will return the randomly generated password as its ONLY result. Display the randomlygenerated password in the main program. Password Criteria:o The password should have a random length of between 7 and 10 characters.o Each character should be randomly selected from positions 33 to 126 from the ASCII table. 1. You must import randint function directly and inline within the random package and it must be thefirst line of code in your program 2.Declaring and using FOUR constants 3. You must use the chr built-in function within your randomPassword function.4. Declaring the main function and invoking randomPassword function. 5. Please do NOT use any special formatting in your print statement.6. Do not use __main__ anywhere in your program code. Sample runs : Run 1. your random password is : "Y)IC>Vm Run 2. your random password is : WM,L8"7 this is the error I am getting Please let me…

C++ You are required to write three overloaded functions called stringOperation that take in the following formal parameters list: Function 1: takes as input a string, ONE character, and an integer n, and returns true if the string contains that character EXACTLY an n number of times. Function 2: takes as input a string and TWO alphabatical characters c1 and c2, and returns true if all the string characters fall in the range between the two passed characters (exclusive) (You must make sure to order the characters first if c2 < c1 ). Function 3: takes as input a string and THREE alphabatical characters c1, c2 and c3. The function reorders the characters in asecnding order, such that c1 holds the smallest character and c3 holds the largest character. The function returns true if the string characters that fall between c1 and c2 (exclusive) is less than the string characters that fall between c2 and c3 (exclusive). Do not write and submit the main subroutine, or any include…
C++ code please Write a program that uses the function isPalindrome . Test your program on the following strings: madam, abba, 22, 67876, 444244, trymeuemyrt Modify the function isPalindrome so that when determining whether a string is a palindrome, cases are ignored, that is, uppercase and lowercase letters are considered the same. Your program should print a message indicating if a string is a palindrome: madam is a palindrome Use expressions: .+*isPalindrome\(\"Madam\"\).+* .+*isPalindrome\(\"abBa\"\).+* .+*isPalindrome\(\"22\"\).+* .+*isPalindrome\(\"67876\"\).+* .+*isPalindrome\(\"444244\"\).+* .+*isPalindrome\(\"trYmeuemyRT\"\).+* in the code.
C++ 10.17 Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs Yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: Yes Ex: If the input is: 42,000 or 1995! the output is: No Hint: Use a loop and the isdigit() function (don't forget to include the cctype library). CODE PROVIDED: #include <iostream>#include <string>#include <cctype>using namespace std; string solve(string userStr) { int start; if(userStr[0]=='-' && isdigit(userStr[1])){ start=1; } else{ start=0; } for(int i=start; i<userStr.length();i++){ if(!isdigit(userStr[i])){ return "No"; } return "Yes" }}
Create a function that accepts a string (of a person's first and last name) and returns a string with the first and last name swapped. Examples NameShuffle("Donald Trump") - "Trump Donald" NameShuffle ("Rosie O'Donnell") - "O'Donnell Rosie" NameShuffle ("Seymour Butts") - "Butts Seymour" • There will be exactly one space between the first and last name.
