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.
