Determine the following information about a positive integer that is passed into a function: (a) is the value a multiple of 7, 11, or 13 (a single yes or no) (b) is the sum of the digits of the value even or odd (c) is the value a prime number Help me Please!!!!

Re: Write a program in C to Determine the following information about a positive inte How far have you got and where are you stuck? Do you understand the requirements?

Re: Write a program in C to Determine the following information about a positive inte for (a) and (b) you can easily use the modulo operator e.g. to test whether it is a multiple of 7: (x%7)==0 e.g. to test even/odd: (x%2) Pieter

Re: Write a program in C to Determine the following information about a positive inte Code: #include <stdio.h> #include <math.h> void test(const int aIntNumber) { // Test for divisibility if(aIntNumber % 7 == 0|| aIntNumber % 11 == 0|| aIntNumber % 13 == 0) { printf("\n%d is divisible!\n", aIntNumber); } else { printf("\n%d is not divisible!\n", aIntNumber); } // Calculate the sum of the digits int anotherIntNum = aIntNumber; int sumOfDigit = 0; while(anotherIntNum > 0) { sumOfDigit += anotherIntNum % 10; anotherIntNum = anotherIntNum / 10; } sumOfDigit += anotherIntNum; // Test if the sum of digits of number is even or odd if(sumOfDigit % 2 == 0) { printf("\nsum of digits in %d is even\n", aIntNumber); } else { printf("\nsum of digits in %d is odd\n", aIntNumber); } // Test if the number is prime or not int s = (int)sqrt((double)aIntNumber); if(aIntNumber > 0 && aIntNumber < 4) { printf("\n%d is prime!\n", aIntNumber); } else if(aIntNumber < 0) { printf("\n%d is not a natural number!\n", aIntNumber); } else if(aIntNumber > 4) { for(int i = 4; i < s; i++) { if(aIntNumber % i == 0) { printf("\n%d is prime!\n", aIntNumber); return; } } printf("\n%d is Not prime!\n", aIntNumber); } else { printf("\n%d is Not prime!\n", aIntNumber); } } int main(int argc, char* argv[]) { test(13); return 0; }
