1. Please use printf. This is C programming. Design a program that will input numeric data type
double into an array. Do this function by designing a function called inputData . Then the
program should sort the data and display the whole content of the array. Sort the array by using
bubble sort ( use the qsort function or /you can Google that ) and design a separate function (call
it displayArray) to display the contents of the array. Please make sure that it is double type and
use printf, I asked before this question but the answer was incorrect, hopefully this time the
answer would be correct. Thanks
Solution
Sort.C
#include <stdio.h>
#define SIZE 5
double* inputData();
void displayArray(double p[]);
void bubbleSot(double a[], int n);
int main()
{
double *a = inputData();
printf("Double Array Elements before Sorting : ");
displayArray(a);
bubbleSot(a, SIZE);
printf("Double Array Elements after Sorting : ");
displayArray(a);
return 0;
}
double* inputData(){
static double arr[SIZE];
int i;
for(i=0; i<SIZE; i++){
printf("Enter Value %d :",i);
scanf("%lf", &arr[i]);
}
return arr;

2. }
void displayArray(double p[]){
int i;
for ( i = 0; i < SIZE; i++ ) {
printf( "%lf ", *(p + i));
}
printf(" ");
}
void bubbleSot(double a[], int n){
int c,d,t;
for (c = 0 ; c < ( n - 1 ); c++)
{
for (d = 0 ; d < n - c - 1; d++)
{
if (a[d] > a[d+1])
{
t = a[d];
a[d] = a[d+1];
a[d+1] = t;
}
}
}
}
Output:
Enter Value 0 :5.5
Enter Value 1 :3.3
Enter Value 2 :2.2
Enter Value 3 :1.1
Enter Value 4 :4.4
Double Array Elements before Sorting :
5.500000 3.300000 2.200000 1.100000 4.400000
Double Array Elements after Sorting :
1.100000 2.000000 3.000000 4.400000 5.000000
