How to find the common element of two arrays in C?

i) Use two index variables i and j, Initialized them with 0. ii) If arr1[i] is smaller than arr2[j] then increment i. iii) If arr1[i] is greater than arr2[j] then increment j. iv) If both are same then print any of the array value and increment both i and j.

How do you check if two arrays have the same elements in the same order?
