How do you create a program that will let the user to enter 10 numbers and arrange it in ascending and descending?

Answer 1

#include "stdio.h"

#define ARRAY_SIZE 10

void fill(float* array, int size);

void spill(float* array, int size, char* delimiter);

void bubble_sort(float* array, int size);

void reverse(float* array, int size);

void swap(float* a, float* b);

int main(int argc, char* argv[]) {

float numbers[ARRAY_SIZE];

fill(numbers, ARRAY_SIZE);

bubble_sort(numbers, ARRAY_SIZE);

spill(numbers, ARRAY_SIZE, " ");

reverse(numbers, ARRAY_SIZE);

spill(numbers, ARRAY_SIZE, " ");

return 0;

}

void fill(float* array, int size) {

int i = 0;

while (i < size)

fscanf(stdin, "%f", array + (i++));

}

void spill(float* array, int size, char* delimiter) {

int i = 0;

while (i < size)

fprintf(stdout, "%f%s", array[i++], delimiter);

fputc('\n', stdout);

}

void bubble_sort(float* array, int size) {

int i, j;

for (i = 0; i < size; i++)

for (j = i; j < size; j++)

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

swap(array + i, array + j);

}

void reverse(float* array, int size) {

int i;

for (i = size / 2; i >= 0; i--)

swap(array + i, array + (size - (i + 1)));

}

void swap(float* a, float* b) {

float c = *a;

*a = *b;

*b = c;

}

fill gets the numbers from input

spill sends them to output

bubble sort will sort the array in ascending order

reverse will reverse the list so that it is in descending order

swap is used to swap two floats

You can change float to double or int depending on which datatype you want to use.
