C++ Sort Array using Functions
“C++ Sort Array using Functions” is the topic of discussion in this tutorial.
What is sorting in C++?
Sorting is the method of arranging the alphabets or numbers in ascending or descending or some another order.
Ascending Alphabets order in C++: a, b, c, d, e, f, ……x, y, z
Descending Alphabets order in C++: z, y, x, ……f, e, d, c, b, a
Ascending Numbers order in C++: 0,1, 2, 3, 4, 5, 6, 7, 8, 9
Descending Alphabets order in C++: 9, 8, 7, 6, 5, 4, 3, 2, 1
Let’s begin with some examples of sorting the array.
