Using the range-based for loop


Question:

Use a range-based for loop to loop through a given vector of integers and determine how many elements in the vector are evenly divisible by either 3 or by  5.
The final result should be stored in an integer variable named count.
The vector of integers has been provided for you and is named vec.


Solution:

#include <iostream>
#include <vector>
using namespace std;

int main() {
    
    vector<int> vec {1,3,5,15,16,17,18,19,20,21,25,26,27,30,50,55,56,58,100,200,300,400,500,600,700};
    //---- WRITE YOUR CODE BELOW THIS LINE----
    int count{0};
    for(auto i:vec){
      if(i%3==0 || i%5==0){
        count++;
      }
    }

    //---- WRITE YOUR CODE ABOVE THIS LINE----
    //---- DO NOT CHANGE THE CODE BELOW THIS LINE----
    cout<<count;
    
    return 0;
}


Output:
18
