Question

c++ language

Consider the series of numbers beginning at user-specified start and running up to but not including user-specified end, so for example start=1 and end=5 gives the series 1, 2, 3, 4. Return a new string[] array containing the string form of these numbers (e.g. "one", "two", "fifty-three" etc., except for multiples of 3, use "Fizz" instead of the number, for multiples of 5 use "Buzz", and for multiples of both 3 and 5 use "FizzBuzz".

Test with numbers from -10 to 110.

Write your string array to a file named YourNameFizzBuzz.txt - one value at a time

#include <iostream>
using namespace std;

int main(int argc, char const *argv[])
{
// declare variables
int Fizz = 3;
int Buzz = 5;
int end_num = 110;
int start_num=-10;
int FizzBuzz = Fizz * Buzz;
// ^ numbers divisible by 3 and 5 are also divisible by 3 * 5
cout<<"Enter Starting number: ";
cin>>start_num;
//checking if number withun range.
if ((start_num < -10) || (start_num >110))
{
cout<<"Entered Number is beyond range(-10 to 110) \n Enter Again:";
cin>>start_num;
}
cout<<"Enter the ending number: ";
cin>>end_num;
//validating input
if ((end_num < -10) || (end_num >110))
{
cout<<"Entered Number is beyond range(-10 to 110) \n Enter Again:";
cin>>end_num;
}

// start the loop, continue until it reaches end
// reaches the 'end'
for( start_num; start_num < end_num; start_num++)
{
if(start_num % FizzBuzz == 0) // divisible by 3 and 5
{
cout<<"FizzBuzz!!\n";
}
else if(start_num % Fizz == 0) // divisible by 3
{
cout<<"Fizz\n";
}
else if(start_num % Buzz == 0)// divisible by 5
{
cout<<"Buzz \n";
}
else // not divisible by 3 or 5
{
cout<<start_num<<endl;
}
}
return 0;
}
