Sort array in ascending order

by · Published · Updated

Write a program in C language which accepts integer values from user, sorts it in ascending order and prints the integers in ascending order.

#include
#include
void main()
{
    int arr[100],i,j,element,no,temp;
    clrscr();
    printf("\nEnter the no of Elements: ");
    scanf("%d", &no);
    for(i=0;i arr[j])
            {
                temp=arr[i];
                arr[i]=arr[j];
                arr[j]=temp;
        	}
        }
    }
    printf("\nSorted array:");
    for(i=0;i

Output:


Enter the no of Elements: 5

Enter Element 1: 2

Enter Element 2: 5

Enter Element 3: 2

Enter Element 4: 5

Enter Element 5: 3

Sorted array:   2       2       3       5       5

    what is the logic for this example?

    Logic here is very simple.
    Take the input in an array.
    then compare the first array element with others. If the first array element is greater than any of the other array element then swap it. The swapping will cause the smallest element to be placed at 1st position.
    Now, compare the second array element with others and not the previous one (1st Array element). If second array element is greater than any of the other array element then swap. If its value is less then no need to swap.
    This swapping will again cause second smallest element to be placed at position 2.

    If you still have any query, then kindly reply. 🙂

    what if the input is -5, 98, 23, 91, 34 ??
    98 and 23 will be swapped
    98 and 91 will be swapped
    34 and 98 will be swapped
    and in the end the result will be
    -5,23,91,34,91
    which is not in order
    am i right ??

    I think the code mentioned below is more efficient.e.g.—If there are 5 no’s, we need only 4 pass in each of the for loop.But in your code there are 5 passes..i.e–one extra pass .we dont need that .
    I may be wrong.whats your opinion, admin?

    code–

    for( i=0;i{
    for( j=i+1;j{

    #include<stdio.h>
    #include<conio.h>
    void main()

    {

    int a[100], i, n, s, j;

    printf(“Enter size of array\t”);

    scanf(“%d”, &n);

    printf(“Enter the elements of array\t”);

    for(i=0;ia[i+1])

    {

    s=a[i];

    a[i]=a[i+1];

    a[i+1]=s;

    }

    }

    }

    printf(“Array in ascending order\n”);

    for(i=0;i

    The logic is simple….here he used arr[i] and arr[j] for an array itself…in it he compared two different elements of an array through i and j…..

      Hi Iyle,

      It is great to hear that this website helped you. If you liked it, share it. 🙂

      Please find below the program that will first print the original array content and then the sorted array.

      #include
#include
void main()
{
    int arr[100],i,j,element,no,temp;
    clrscr();
    printf("\nEnter the no of Elements: ");
    scanf("%d", &no);
    for(i=0;i arr[j])
            {
                temp=arr[i];
                arr[i]=arr[j];
                arr[j]=temp;
            }
        }
    }
    printf("\nSorted array:");
    for(i=0;i

    this is code for acs and des both

    #include
    #include
    void main()
    {clrscr();
    int array[5],des[5],acs[5];
    int temp;
    int i;
    for (i=0;i<5;i++)
    {
    printf("enter number: ");
    scanf("%d",&array[i]);

    }

    for(int l=0;l<5;l++)
    {
    des[l]=array[l];
    acs[l]=array[l];
    }

    printf("\n\ndes order:");
    for(i=0;i<4;i++)
    {
    for(int j=i+1;j<5;j++)
    {if(des[i]<des[j])
    {temp=des[i];
    des[i]=des[j];
    des[j]=temp;}
    }
    }
    for(int a=0;a<5;a++)
    {printf("\n%d",des[a]);}

    printf("\n\nacs order:");
    for(i=0;i<4;i++)
    {
    for(int j=i+1;jacs[j])
    {temp=acs[i];
    acs[i]=acs[j];
    acs[j]=temp;}
    }
    }
    for(a=0;a<5;a++)
    {
    printf("\n%d",acs[a]);
    }
