Use 2D Array Notation to Declare Array of Strings in C Strings in C are simply a sequence ofcharsstored in a contiguous memory region. One distinction about character strings is that there is a terminating null byte\0stored at the end of the sequence, denoting one string’s end. If we ...

Declaring and using an array in C To declare an array, you simply need to specify the data type of the array elements, the variable name and the array size. For example, if you want to declare an integer array with four elements, you’d use: ...
To dynamically create a 2D array, you first declare a double pointer. Then, you allocate memory for each row using a loop, effectively creating an array of pointers to arrays. It’s crucial to free the allocated memory properly to avoid memory leaks. This involves freeing each row first, ...

In the above example, we defined a function ‘func’ that takes two integers as inputs and returns an integer. In the main() function, we declare a function pointer ‘fptr’ and then assign value to it. Note that, name of the function can be treated as starting address of the functio...
