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,

Learning C++ can be a lot of fun, and one of the very first things beginners often do is write a program to add two numbers. It may sound simple, but this small task teaches some of the most important programming skills, like handling input and output, performing arithmetic, and working with variables. Adding numbers

In C programming, 2D arrays are essential for representing grids, tables, or matrices. While static arrays are simple to use, they require the number of rows and columns to be fixed at compile time, which limits flexibility. Dynamic memory allocation solves this problem, allowing programs to create arrays whose size can be determined at runtime

Dynamic memory allocation in C provides flexibility by allowing programs to request memory at runtime. Sometimes, the initially allocated memory may not be enough, or you may need to reduce the size of a memory block. The realloc() function allows you to resize previously allocated memory without losing the existing data. Using realloc() is essential
