how to measure the length of the array in C++ code example
Example 1: c++ get length of array
int arr[5];
int len = sizeof(arr) / sizeof(arr[0]);
// returns 5
Example 2: find length of array c++
#include <iostream>
using namespace std;
int main() {
int arr[5] = {4, 1, 8, 2, 9};
int len = sizeof(arr)/sizeof(arr[0]);
cout << "The length of the array is: " << len;
