Question

#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 division:vec){

if(division%5==0||division%3==0){

count=division;

cout<<count<<endl;

};

};

cout<<sizeof(count) <<endl;

return 0;

}

at end of this it is showing 4 why???????????

Answer 1

Because the size of the an integer is 4 bytes, which is what you are printing out

in the very last statement before the return:

cout<<sizeof(count) <<endl;

If you are trying to find the # of elements in the vector, just use the size() method:

vec.size();
