C program for sorting- ascending order, descending order

/*sorting in an ascending order */

#include<stdio.h>

void

main()

{

                int i,j,n;

                float a[100],t;

                printf("enter the total number of data:");

                scanf("%d",&n);

                printf("enter  the data :\n");

                for(i=0;i<n;i++)

                scanf("%f",&a[i]);

                for(i=0;i<(n-1);i++)

                {

                                for(j=i+1;j<n;j++)

                                {

                                                if(a[i]>a[j])

                                                {

                                                                t=a[i];

                                                                a[i]=a[j];

                                                                a[j]=t;

                                                }

                                }

                }

                printf("\n sorted array in ascending is :\n");

                for(i=0;i<n;i++)

                                printf("%f \n",a[i]);

}

Result:

enter the total number of data:8

enter the data :

78

90
