Goals: Practicing arrays and functions Create a program that will read values from a file called Lab8.dat (posted on Canvas) and store it into an array using a function other than main. The number of values in the file is less than 300 and all the values are whole numbers. The actual number of values stored in the file should be returned to the function call. Your program should contain another function that accepts the array, the number of values in the array, and a whole number. This function should use a loop to count how many values in the array are evenly divisible by the whole number and return this count to the function call. The loop should not contain more than 3 arithmetic operatorsand+count as arithmetic operators, but does not) The main function should call the function to read the data from the file. Next, ask the user to enter a whole number between 2 and 20 (you may assume the user enters a correct value). This whole number is the value to divide each element in the array. Next, call the function to determine how many values in the file are evenly divisible by the entered whole number and output the returned count. The message should be something like 35 of the 182 values in the file were evenly divisible by 19. with the underlined values replaced by the your calculated values and the user's input. Do not use any concepts beyond Chapter 7 of your tex he introductory comments for the program your code should contain comments for each function other than main that states the purpose of the function, input to the function (b nput from the function call and interactive input), output from the function (both information sent back to the function call and interactive output), and processing performed in the function. Follow the Assignment Guidelines posted on Canvas. othExplanation / Answer
Code
#include <iostream>
#include <fstream>
#include <vector>
using namespace std;
int readFile(string,int[]);
void detectWhole(int[],int,int);
int main()
{
int num;
cout<<"Enter the number -->";
cin>>num;
int numbers[300];
int n=readFile("Lab8.txt",numbers);
cout<<"The number of integers in a file is-->"<<n<<endl;
detectWhole(numbers,n,num);
return 0;
}
int readFile(string filename, int number[])
{
int num;
int count=0;
ifstream in(filename,ios::in);
if(in.is_open())
{
while((in>>num)>0)
{
number[count]=num;
count++;
}
in.close();
}
else
cout<<"unable to open file"<<endl;
cout << "Numbers: ";
for (int i=0; i<count; i++){
cout << number[i] << ' ';
}
return count;
}
void detectWhole(int number[],int n,int num)
{
int count=0;
for(int i=0;i<n;i++)
{
if(number[i]%num==0)
count++;
}
cout<<count<<" of the "<<n<<" values in the file were evenly divisible by "<<num<<endl;
}
