Practical C Programming

How to do it…

1. Define two arrays of a certain size and assign elements of your choice to both the arrays. Let's assume that we created two arrays called p and q, both of size four elements:

Figure 1.11

2. Define one more array. Let's call it array r, to be used for storing the elements that are common between the two arrays.
3. If an element in array p exists in the array q, it is added to array r. For instance, if the element at the first location in array p, which is at p[0], does not appear in array q, it is discarded, and the next element, at p[1], is picked up for comparison.

4. And if the element at p[0] is found anywhere in array q, it is ...
