How to Create an Array with Variable Size in C ?

Creating an Array with Variable Size

In C , when attempting to declare an array with a variable size, such as in the provided code snippet, one encounters an error due to the lack of a fixed size. To address this issue, various approaches can be considered.

Avoidance of Variable Length Arrays

Variable length arrays, as attempted in the provided code, are ill-formed in C . Therefore, it is essential to employ alternative solutions, such as:

• std::vector: This container allows for dynamic resizing of the array. Elements can be added and removed as needed, making it ideal for handling varying data sizes.

Dynamic Memory Allocation

Alternatively, dynamic memory allocation using the "new" operator can be utilized to allocate memory for the array at runtime. However, this approach requires manual deallocation using the "delete[]" operator to avoid memory leaks.
