How do I attach a file on the computer?
strojnjashka [21]
When you select 'ask your question' a box will appear and it will ask you to write your question. Underneath the text box you'll see a 'pi' sign and an 'omega' sign and next to that you'll see a paperclip sign. Click the paperclip sign and then choose the file/s you want to attach.

I have attached a docx (document) if you don't get what i mean.
Hope it helped :)

Write a function which sorts the queue in order from the smallest value to the largest value. This should be a modified version
PilotLPTM [1.2K]

Answer:

#include <iostream>

using namespace std;

void swap(int *a,int *b){    //function to interchange values of 2 variables

   int temp=*a;

   *a=*b;

   *b=temp;

}

void sort(int queue[],int n)

{

   int i,j;

   for(i=0;i<n;i++)      //to implement bubble sort

   {

       for(j=0;j<n-i-1;j++)

       {

           if(queue[j]>queue[j+1])

               swap(queue[j],queue[j+1]);    //to swap values of these 2 variables

       }

   }

}

int main()

{

   int queue[]={6,4,2,9,5,1};

   int n=sizeof(queue)/4;  //to find length of array

   sort(queue,n);

   for(int i=0;i<n;i++)

       cout<<queue[i]<<" ";

   return 0;

}

OUTPUT :

1 2 4 5 6 9

Explanation:

In the above code, Queue is implemented using an array and then passed to a function sort, so that the queue can be sorted in ascending order. In the sort function, in each pass 2 adjacent values are compared and if lower index value is greater than the higher one they are swapped using a swap function that is created to interchange the values of 2 variables.
