C++ Sort Array using Functions

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.

Example Program for Sorting the Array in C++

Following program covers the “Example Program for Sorting the Array in C++”.

#include<iostream>
using namespace std;
int main()
{
	int array[100];
	int size;
	int b;
	
	cout<<"enter number of values"<<endl;
	cin>>size;
	
	cout<<"enter values"<<endl;
	for(int i=0; i<size; i++)
	{
		cin>>array[i];
	}
	
	for(int i=0; i<size; i++)
		{
			for(int j=i+1; j<size; j++)
				{
					if(array[i]>array[j])
						{
							b=array[i];
							array[i]=array[j];
							array[j]=b;
						}
				}
		}
		cout<<endl<<"the sorted values are"<<endl;
		for(int i=0; i<size; i++)
			{
				cout<<array[i];
			}
}
