swapping array value

I am trying to sort array in increasing order

my approach for sequence 5 4 3 2 1 is like following

5 > 4 True 4 5 3 2 1

5 > 3 True 4 3 5 2 1

5 > 2 True 4 3 2 5 1

5 > 2 True 4 3 2 1 5


4 > 3 True 3 4 2 1 5

4 > 2 True 3 2 4 1 5

4 > 1 True 3 2 1 4 5

and so on ...

Code:

---

  #include<stdio.h>

int main()
{
    int array[5] = {5, 4, 3, 2, 1 };
        int temp[5];
       
        for ( int i = 0; i < 5; i++)
        {
                for ( int j = 0; j < 5; j++)
                {
                        if (array[i] > array[j+1])
                        {
                                temp[i] =  array[i];
                        }                       
                       
                       
                }
        }
       
        for ( int i = 0; i < 5; i++)
        {
                printf("%d", temp[i]);
        }
       
        return 0;
}

I am struggling in swapping array value

I know swapping

x = 1
y = 100
temp =x
x = y = 100
y = temp = 1

So why can't you replace those things with array[i] and array[j] ?

Also, your j loop has the same mistake as your previous thread.
You don't start at 0, you start at i

I am struggling with swapping inside inner loop

Code:

---

  #include<stdio.h>

int main()
{
    int array[5] = {5, 4, 3, 2, 1 };
        int temp[5];
       
        for ( int i = 0; i < 5; i++)
        {
                for ( int j = i+1; j < 5; j++)
                {
                        if (array[i] > array[j])
                        {
                                temp[i] =  array[j];
                                array[i] = temp[i]; 
                        }                       
                       
                       
                }
        }
       
        for ( int i = 0; i < 5; i++)
        {
                printf("%d", temp[i]);
        }
       
        return 0;
}

There is no temp[i]. You only ever need one temporary variable, to hold the value that you are swapping right now. So just store and load to temp.

And why would you print temp[i]? You're not sorting that array, you're sorting the array array. Print that!

I tried but it doesn't give correct output

Code:

---

  #include<stdio.h>

int main()
{
    int array[5] = {5, 4, 3, 2, 1 };
       
        int temp;
       
        for ( int i = 0; i < 5; i++)
        {
                for ( int j = i+1; j < 5; j++)
                {
                        if (array[i] > array[j])
                        {
                                temp =  array[i];
                                array[j] = array[i]; 
                                array[j] = temp;
                        }                       
                       
                       
                }
        }
       
        for ( int i = 0; i < 5; i++)
        {
                printf("%d", array[i]);
        }
       
        return 0;
}

Because it is wrong still...
Pay attention on what you did on swapping...
