Question

Please write program in C++ Write a function called randCount with no parameters. The function should randomly generate 5 numbers between 8 to 15 and counts how many times a multiple of 2 occurred. Return the answer to the calling function. please write the program in C++

Answer 1

In this C++ program,

- We have defined a function named randCount which has no parameters and returns the count of multiples of 2 from the 5 generated numbers in the range of 8 to 15.
- In the main, we are validating by calculating the function and printing the returned output from the function.

(I believe that I made the code simple and understandable. If you still have any query, Feel free to drop me a comment)

Code:

#include <iostream>
using namespace std;

//Defined a function with no parameters and return an int
int randCount()
{
srand(time(NULL));
int count=0;//To store the count of multiples of 2
  
//Iterating to generate 5 elements
for(int i=0;i<5;i++)
{
//generating random numbers in range of 8 and 15
int number=(rand()%8)+8;
  
cout<<number<<" ";//"PLEASE REMOVE THIS, IT IS PURELY FOR VALIDATION"
  
//Check if the generated number is a multiple of 2 and increment the count
if(number%2==0)
count++;
}
return count; //return the count
}
int main()
{
cout<<endl<<"The count is "<<randCount()<<endl;
return 0;
}

Please check the compiled program and its output for your reference:

main.cpp 1 #include <iostream> 2 using namespace std; 3 4 //Defined a function with no parameters and return an int int randCount() 6-{ 7 srand(time(NULL)); int count=0;//To store the count of multiples of 2 5 8 14 //Iterating to generate 5 elements 11 for(int i=0;i<5;i++) 12 - 13 //generating random numbers in range of 8 and 15 int number(rand()%8)+8; 15 16 cout<<number<<" ";//"PLEASE REMOVE THIS, IT IS PURELY FOR VALIDATION" 17 18 //Check if the generated number is a multiple of 2 and increment the count 19 if(number%2==0) 20 count++; 21 22 return count; //return the count 23 } 24 int main() 25-{ 26 cout<<endl<<"The count is "<<randCount()<<endl; 27 return ; 28 } 29 }

Output:

input 8 11 10 9 12 The count is 3 ... Program finished with exit code o Press ENTER to exit console.
