C program to sort character array (string) in ascending order

Below is the simple C program that will accept the character string from the user, calculates the length of the string and performs sorting operation on the string. The program will sort the character array in ascending order and display the result string (character array).

Here we go,

#include<stdio.h>
#include<conio.h>
void main()
{
	clrscr();
	int i,j;
	char *arr;
        
        //accept character array string from user
	printf("Enter character string: ");
	gets(arr);

	//get the length of array in the variable counter
	int counter = 0;
	while(arr[counter] != NULL){
		counter = counter + 1;
	}

        //apply ascending sorting algorithm
	for(i=0; i<counter; i++)
	{
		for(j=i; j<counter;j++)
		{
			if (arr[i] > arr[j])
			{
				char arrtemp;
				arrtemp = arr[i];
				arr[i] = arr[j];
				arr[j] = arrtemp;
			}
		}
	}

        //display the final result
	for(i=0;i<counter; i++)
	{
		printf("%c", arr[i]);
	}
	getch();
}
