C++ Array – Loop through Elements

In this C++ tutorial, you will learn how to iterate over array and traverse the elements in array using loop statements like While loop, For loop, or Foreach loop, with examples.

Loop through Array in C++

You can loop through array elements using looping statements like while loop, for loop, or for-each statement.

1. Iterate over array using While loop

In this example, we will use C++ While Loop to iterate through array elements.

C++ Program

#include <iostream>
using namespace std;

int main() {
   int arr[7] = {25, 63, 74, 69, 81, 65, 68};
   
   int i=0;
   while (i < 7) {
      cout << arr[i] << "  ";
       i++;
   }
}

Output

25  63  74  69  81  65  68

2. Iterate over array using For loop

In this example, we will use C++ For Loop to iterate through array elements.

C++ Program

#include <iostream>
using namespace std;

int main() {
   int arr[7] = {25, 63, 74, 69, 81, 65, 68};
   
   for (int i=0; i < 7; i++) {
      cout << arr[i] << "  ";
   }
}

Output

25  63  74  69  81  65  68

3. Iterate over array using ForEach statement

In this example, we will use C++ Foreach statement to iterate through array elements.

C++ Program

#include <iostream>
using namespace std;

int main() {
   int arr[7] = {25, 63, 74, 69, 81, 65, 68};
   
   for (int element: arr) {
      cout << element << "  ";
   }
}

Output

25  63  74  69  81  65  68

Conclusion

In this C++ Tutorial, we learned how to iterate through elements of Array using looping statements.
