C Exercises: Sort an array using pointer
14. Sort Array Using Pointer
Write a program in C to sort an array using a pointer.
Visual Presentation:
Sample Solution:
C Code:
#include <stdio.h>
int main() {
int *a, i, j, tmp, n;
printf("\n\n Pointer : Sort an array using pointer :\n");
printf("--------------------------------------------\n");
// Input the number of elements to store in the array
printf(" Input the number of elements to store in the array : ");
scanf("%d", &n);
// Input elements into the array
printf(" Input %d number of elements in the array : \n", n);
for (i = 0; i < n; i++) {
printf(" element - %d : ", i + 1);
scanf("%d", a + i);
}
// Sorting the array using pointer
for (i = 0; i < n; i++) {
for (j = i + 1; j < n; j++) {
if (*(a + i) > *(a + j)) {
// Swap elements if they are in the wrong order
tmp = *(a + i);
*(a + i) = *(a + j);
*(a + j) = tmp;
}
}
}
// Displaying the sorted array elements
printf("\n The elements in the array after sorting : \n");
for (i = 0; i < n; i++) {
printf(" element - %d : %d \n", i + 1, *(a + i));
}
printf("\n");
}
Sample Output:
Pointer : Sort an array using pointer :
--------------------------------------------
Input the number of elements to store in the array : 5
Input 5 number of elements in the array :
element - 1 : 25
element - 2 : 45
element - 3 : 89
element - 4 : 15
element - 5 : 82
The elements in the array after sorting :
element - 1 : 15
element - 2 : 25
element - 3 : 45
element - 4 : 82
element - 5 : 89
