Write a program with a main and a helper function pattern1. The main gets an integer from the user and passes that to the helper function, with a function call. The helper function will print out the Pascal triangle up to the depth that user has requested. For example for testing, if the user enters 4, the following pattern will be printed:

This is for C++ Design a Boolean function named isPrime(), which takes an integer as an argument and returns True if the argument is a prime number, or False otherwise.  Display all of the prime numbers from 1 through 100.  The program should have a loop that calls the isPrime() function.  11 Prime Numbers List  (15 points) Use CONSTANTS to set the maximum number in the table to 100 and the number of entries per row to 5.   Table of prime numbers from 1 to 100  1   2   3   5   711 13 17 19 2329 31 37 41 4347 53 59 61 6771 73 79 83 8997Press any key to continue . . . Experiment: What is the result if the maximum number is changed, for example, to 1000?

I'm trying to create a c program that will take in a ten-digit ISBN number and then check to see if the number is valid by calculating its weighted sum. This is the code that I have up to know, but I'm not sure what to do next. Can you give me some pointers?     DOCUMENTATION-------------This program will determine if an ISBN number is valid by calculating its weighted sum.********************************************************************/#include <stdio.h>#include <stdbool.h> #define ISBN_SIZE 10#define MOD_NUM 11 void printInstructions(void);void getIsbn(int isbnArray[]);void printIsbn(int isbnArray[]);int calculateWeightedSum(int isbnArray[]);bool isIsbnValid(weightedSum);void printGoodbye(void); int main(){int isbnArray[ISBN_SIZE] = {0}; printInstructions();getIsbn(isbnArray); printf("\n\nThe ISBN ");printIsbn(isbnArray); if(isIsbnValid(calculateWeightedSum(isbnArray))){printf(" is valid.");}else{printf(" is not valid.");} printGoodbye(); return 0;}…
