c++ array loop

#include <iostream>
using namespace std;

int main() {

  int i, n;
  float arr[100];

  cout << "Enter total number of elements(1 to 100): ";
  cin >> n;
  cout << endl;

  // Store number entered by the user
  for(i = 0; i < n; ++i) {
    cout << "Enter Number " << i + 1 << " : ";
    cin >> arr[i];
  }

  // Loop to store largest number to arr[0]
  for(i = 1;i < n; ++i) {

    // Change < to > if you want to find the smallest element
    if(arr[0] < arr[i])
      arr[0] = arr[i];
  }

  cout << endl << "Largest element = " << arr[0];

  return 0;
}

array and for loop in c++

//inserting array elements in cpp
#include<iostream>
using namespace std;
int main()
{
  int arr[100];//you can give any data type and any array size you want
  for(int i=0;i<100;i++)
  {
    cin>>arr[i];
  }
  return 0;
}

for loop with array c++

int v[] = {1,2,3,4,5};
for (int n : v)
  cout << n << endl;
//make sure to compile with -std=c++11

C++, for-loop over an array array

/*sizeof(array_scores) is a pointer to array_scores[], 
and has to be divided by each first-object[0]*/
for(int a = 0; a < sizeof(array_scores)/sizeof(array_scores[0]); a = a + 1 ){
	cout << "for loop, a = " << array_scores[a] << " at position " << a << "
";
}
