A regular expression (shortened as regex or regexp; also referred to as rational expression) is a sequence of characters that specifies a search pattern. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. using regex create a python program to verify the string having each word start from 'f'? It should return True otherwise false.
✓ Allowed languages C Problem Statement Write a C Program that determine the number of occurence of a particular character in a string. Input Input starts with a number N and is followed by N pairs of character c and string s Output Output the number of times the character c appears in string s Limits 1

Input Input starts with a number N and is followed by N pairs of character c and string s Output Output the number of times the character c appears in string s Limits 1 < N < 20 Notes Problems will have test cases that are not listed in their specification. Your solution must produce the right output for these hidden test cases. Sample Input #1 4 'h' "hello world" 'o' "hodor" 'a' "aaaaaaaaa" 'b' "mnopqrst" Sample Output #1 1 2 9 0 Copy Copy

Instructions The python "try" keyword is very powerful in that it can, among other things, prevent a program from ending abnormally because of invalid numeric input. Write a python program with two functions/modules that does the following: .main() accepts input and calls a function to test if the input is a number and displays a message regarding the result of that numeric test • numTest() is passed an input string, tests to see if the string is numeric and returns the necessary information to main() . a NULL input (just pressing the enter key) ends the program . DO NOT USE THE BUILTIN PYTHON FUNCTION FOR NUMERIC TESTING Be sure to use clear prompts/labeling for input and output.
Urgent solve using C++ Notes: The maximum size of any c-string in this lab is 100 characters and it should be dynamically allocated in the constructor and de-allocated in the destructor. For Visual Studio you need to put the following line as first top line in your source code file: #define _CRT_SECURE_NO_WARNINGS Question 1: The class Person contains the following properties and functions: Name (c-string ), private Age (int), private Address (c-string), private Constructors ( default and non-default) Getters and Setters Destructor: to free the memory and print the message “Object with name [PERSON_NAME] is dead” where PERSON_NAME is the person name for the object being disposed. Print function to print the details of the employee. Test your class with the following main: int main() { Person per1; Person per2("Ahmad", "AUS Campus", 21); cout << "Person per1 :\n"; per1.print(); cout << "\nPerson per2 :\n"; per2.print(); cout<<"\nTesting the setters…
Specification: Read sentences from the user until * is entered. Show the number of words in each sentence that contain a stretch of non-z characters with exactly 2 vowels. A stretch starts from the start of the word or after a 'z'. A stretch terminates just before another 'z' or at the end of the word. Examples: 1. Matching words: zoo, azozooza, GONZALEZ 2. Non-matching words: ozo, azoooza The sentences contain no punctuation, the words are separated by one or more spaces, and the characters may be upper or lower case. Keep reading sentences until the user enters "*". Sample I/O: Sentence: azoooza azooza zoo azoo Matching words = 3 Sentence: GONZALEZ passes the ball to VAZQUEZ Matching words = 3 Sentence: azozototzeti Matching words = 1 Sentence: * Done
C code blocks Implement a function which receives a character array and determines if the word is a palindrome or not. A palindrome is a string that is spelt the same way forwards and backwards (see the example below). The function should return 1 if the character array is a palindrome and 0 if it is not. Write the entire function in the space below. Your answer should not include the function prototype, the main function or any include statements. The function should not contain any printf statements. Define your function in the same way as the given function prototype. Function prototype: int palindrome(char a[]); For example: Input Result hello 0 radar 1 acca 1
