Write a C function boolean isPrime (int n), that would take a positive integer n as a parameter and return true or false whether the number is a prime number. You should check the range of n and print proper message (For example, if n is a genitive number, you should print out an error message).

Expert Solution

#include <stdio.h>
#define bool int
#define true 1
#define false 0

bool isPrime(int number)
{
int flag = true;
for(int i=2;i<=number/2;i++)
{
if(number%i == 0) // divisible by any number between 2 to number -1
flag = false;

}
return flag;
}
int main(void) {

   int num;

   printf("Enter the number to be checked if its prime : ");
   scanf("%d",&num);
   if(num < 0)

   printf("\nError : The entered number is negative ");
   if(num == 1 || num ==2 || num ==3)
   printf("Error : ");

   else if(isPrime(num) == true)
   printf("\nNumber %d is prime",num);
   else
   printf("\nNumber %d is not prime",num);

   return 0;
}

Output:

Enter the number to be checked if its prime : 
Number 13 is prime

In C++, type a function function(int n, int base) that converts a positive integer x to any base between 2 and 9. The function HAS to do this using a stack, and using methods from below: +isEmpty(): boolean +push(newEntry: ItemType): boolean +pop(): boolean +peek(): ItemType (Also, type a program to test the function). Hint: could use simple iteration continually divides the decimal number by base and keeps track of the remainder by using a stack.

Write a C function, for example void sumOfPrime(int n), that takes a positive int n as a parameter, put all prime numbers less than n into an array, and print out the array and the sum of the numbers in that array. You can use the isPrime function above to save time.

Find the runtime of this function, where n is an integer. int function(int n) { int a = 0; for (int i = n; i > 0; i--) { for (int j = 0; j < i; j++) { a = a + i + j; } } return a; } Find the runtime of this function, where m and n are two integers. int f(int m, int n) { if (m==1 || n==1) { return 1; } return f(m,...

Write a function decimalToBinary(n) that converts a positive decimal integer n to a string representing the corresponding binary number. Do the conversion by repeatedly dividing the number n by 2 using integer division, keepting track of the remainders, until the number is reduced to 0. The remainders written in reverse order form the binary number string. Do integer division of 5 by 2, so that N//2 is 2 with remainder 1. Now divide 2 by 2 to get 1 with...

Write a value returning function called isPrime. This function accepts integer number as parameter and checks whether it is prime or not. If the number is prime the function returns true. Otherwise, function returns false. A prime number is the number that can be divided by itself and 1 without any reminder, i.e. divisible by itself and 1 only. DO THIS USING C++ LANGUAGE .WITH UPTO CHAPTERS 5 (LOOP).

Write function boolean isSorted(int a[], int size). The function returns true if array a is sorted in either ascend order or descend order; false otherwise. c++

C Write a function int sort(int** arr, int n) that takes as input an array of int pointers, multiplies the ints the pointers point to by -1, and then sorts the array such that the values pointed to by the pointers are in decreasing order. For example, if the array is size 10 the pointer at index 0 will point to the largest value after multiplying by -1 and the pointer at index 9 will point to the smallest value...

C++ 1. Write a function decimalToBinary() that takes in a positive integer as a parameter and use as stack to convert the integer to a its corresponding binary representation. Hint: divide the integer by 2. 2. A palindrome is a string of characters (a word, phrase, or sentence) that is the same regardless of whether you read it forward or backward—assuming that you ignore spaces, punctuation, and case. For example, Race car is a palindrome. So is A man, a...
