This means that the memories of all elements of an array are allocated together and are continuous. The name of an array is the pointer to the first element of the array. Enter the size of array 4 Value of n[0] : 12 Value of n[1] : Value of n[2] : Column 0 Column 1 Column 2 Column 3 Row 0 a[0][0] a[0][1] a[0][2] a[0][3] Row 1 a[1][0] a[1][1] a[1][2] a[1][3].

While assigning values to an array at the time of declaration, there is no need to give size in one dimensional array, but in 2D array, we need to give at least the value of the second dimension.

Programming is a skill best acquired by practice and example rather than from books. Further Readings.

If the compiler can track where some pointers came from, in order to deduce the absence of aliasing, grand. This is a particularly easy case of it, but I think it's still correct to say that it's "interpreted as a pointer". Certainly it is in the language , even if typical implementations special-case optimizing it.

Steve: Hmm, true. I wasn't aware that arrays were specifically defined in this way. I stand corrected then. Nawaz Nawaz k gold badges silver badges bronze badges. Tony: There are a few quirks on gcc approach exactly because the treatment of arrays are different in both languages.

Given below is the picture representation of an array. Take a step-up from those "Hello World" programs. Learn to implement data structures like Heap, Stacks, Linked List and many more! Check out our Data Structures in C course to start learning today. Why do we need arrays? We can use normal variables v1, v2, v3,..

The idea of an array is to represent many instances in one variable. It can be done by specifying its type and size, by initializing it or both. Use of less line of code as it creates a single array of multiple elements.

Easy access to all the elements. Traversal through the array becomes easy using a single loop.
