Array creation and operation program in c

Merging two arrays in a third array means first copying the elements of the first array into the third array and then copying the elements of the second array in the third array.

Therefore, the merged array contains the elements of the first array followed by the elements of the second array. One dimensional array ex: int a[10] Two-dimensional array ex: int a[10][10] Multi-dimensional array ex: int a[10][10][10] Also, read:.

Here, we haven't specified the size. However, the compiler knows its size is 5 as we are initializing it with 5 elements.

Here, we have used a for loop to take 5 inputs from the user and store them in an array. Then, using another for loop, these elements are displayed on the screen. Now let's say if you try to access testArray[12]. The element is not available. This may cause unexpected output undefined behavior. Sometimes you might get an error and some other time your program may run correctly.

It is not an efficient approach however is the basic building block to understand sorting of arrays.

We will be sorting the array in ascending order. Approach using Bubble Sort: Ascending Order. Operation on Arrays in C — Part 1 There are a number of operations that can be performed on an array which are: Traversal Copying Reversing Sorting Insertion Deletion Searching Merging We shall see traversal, copying, reversing and sorting in this section.

Traversal: Traversal means accessing each array element for a specific purpose, either to perform an operation on them , counting the total number of elements or else using those values to calculate some other result.

Since array elements is a linear data structure meaning that all elements are placed in consecutive blocks of memory it is easy to traverse them. In order to so, we need to know the length of original array in advance.

The destination array should also be of the same or greater size as that of original array in order to hold the array contents. The copying of elements would be done on index by index basis. There are two methods to perform reversal of array. For the below two approaches using same logic you can later try incorporating functions and pointers. Let us now see the two basic approaches.
