C Program To Arrange Numbers in Ascending Order

In this post, we will learn how to arrange numbers in ascending order using C Programming language.

This program asks the user to enter n elements, then this program sorts and arrange the entered numbers in the ascending order.

We use two methods to write this program. These two methods are as follow:- 

1. Using Standard Method
2. Using User-defined function

So, without further ado, let’s begin this tutorial.

C Program To Arrange Numbers in Ascending Order

// C Program To Arrange Numbers in Ascending Order
#include <stdio.h>
int main(){
    int num[25];
    int a, j, i, n;
    
    // Asking for input
    printf("Enter total no. of elements: ");
    scanf("%d", &n);
    
    printf("Enter the numbers one by one\n");
    for (i = 0; i < n; ++i){
        scanf("%d", &num[i]);
    }
    for (i = 0; i < n; ++i){
        for (j = i + 1; j < n; ++j){
            if (num[i] > num[j]){
                a = num[i];
                num[i] = num[j];
                num[j] = a;
            }
        }
    }
    printf("Numbers in ascending order: \n");
    for (i = 0; i < n; ++i){
        printf("%d\n", num[i]);
    }
    return 0;
}

Output

Enter total no. of elements: 5
Enter the numbers one by one
12
17
5
32
44
Numbers in ascending order: 
5
7
12
32
44

How Does This Program Work ?

    int num[25];
    int a, j, i, n;

In this program, we have defined four int data type variables named as a, j, i and n.

    // Asking for input
    printf("Enter total no. of elements: ");
    scanf("%d", &n);
    printf("Enter the numbers one by one\n");
    for (i = 0; i < n; ++i){
        scanf("%d", &num[i]);
    }

Then, the user is asked to enter the total no. of elements which the user wants to arrange in the ascending order.

    for (i = 0; i < n; ++i){
        for (j = i + j; j < n; ++j){
            if (num[i] > num[j]){
                a = num[i];
                num[i] = num[j];
                num[j] = a;
            }
        }
    }

Now, We sort the elements of the array in ascending order.

    printf("Numbers in ascending order: \n");

Finally, the numbers are printed in the ascending order using printf() function.

C Program To Arrange Numbers in Ascending Order Using User-defined function

// C Program To Arrange Numbers in Ascending Order
#include <stdio.h>
int arrange(int num[], int count){
    int i, j, k, temp;
    
    for (i = 0; i < count; ++i){
        for (j = i + 1; j < count; ++j){
            if (num[i] > num[j]){
                temp = num[i];
                num[i] = num[j];
                num[j] = temp;
            }
        }
    }
    printf("Numbers in ascending order: \n");
    for (k = 0; k < count; ++k){
        printf("%d\n", num[k]);
    }
}

int main(){
    int i, count, num[25];
    
    // Asking for Input
    printf("Enter total no. of elements: ");
    scanf("%d", &count);
    printf("Enter elements one by one: \n");
    
    for (i = 0; i < count; ++i){
        scanf("%d", &num[i]);
    }
    arrange(num, count);
    return 0;
}

Output

Enter total no. of elements: 3
Enter elements one by one: 
25
448
17
Numbers in ascending order: 
17
25
448
