How to Print Arrays in C : Iterative and Alternative Approaches?

Printing Arrays Conveniently in C

Contrary to popular belief, printing arrays in C is indeed possible. Let's delve into a simple yet effective method to print array elements:

1. Iterative Approach:

You can iterate through the array elements and print each one individually using the following syntax:

for (int i = 0; i < arraySize; i++) {
  std::cout << array[i] << " ";
}

This code initializes an integer variable i to 0, representing the index of the first array element. The loop continues as long as i is less than the array size (arraySize). Within the loop, it prints the value of the array element at index i followed by a space. This process repeats until all elements are printed.

2. Alternative Approach (Avoids Overflow):

As pointed out by Maxim Egorushkin, the iterative approach has the potential to overflow if numElements is sufficiently large. To safeguard against this issue, consider the following alternative:

for (int i = numElements - 1; i >= 0; i--) {
  std::cout << array[i] << " ";
}

In this variation, the loop starts from the last index (numElements - 1) and decrements through the array. This eliminates the risk of overflow and ensures that all elements are printed in reverse order.
