In C programming, 2D arrays are widely used to represent matrices, tables, or grids. Static 2D arrays are simple but have a fixed size determined at compile time. To handle variable-sized arrays or large datasets efficiently, dynamic memory allocation using malloc() is preferred. Dynamic allocation allows programs to create 2D arrays whose dimensions are determined

Dynamic memory allocation in C provides flexibility for programs to request memory at runtime using functions like malloc(), calloc(), or realloc(). While this allows for variable-sized data and efficient memory use, it comes with the responsibility of releasing memory when it is no longer needed. Failing to free dynamically allocated memory results in memory leaks,
