void quicksort(int [10],int,int);

int main(){
  int x[20],size,i;

  printf("Enter size of the array: ");
  scanf("%d",&size);

  printf("Enter %d elements: ",size);
  for(i=0;i<size;i++)
    scanf("%d",&x[i]);

  quicksort(x,0,size-1);

  printf("Sorted elements: ");
  for(i=0;i<size;i++)
    printf(" %d",x[i]);

  return 0;
}

void quicksort(int x[10],int first,int last){
    int pivot,j,temp,i;

     if(first<last){
         pivot=first;
         i=first;
         j=last;

         while(i<j){
             while(x[i]<=x[pivot]&&i<last)
                 i++;
             while(x[j]>x[pivot])
                 j--;
             if(i<j){
                 temp=x[i];
                  x[i]=x[j];
                  x[j]=temp;
             }
         }

         temp=x[pivot];
         x[pivot]=x[j];
         x[j]=temp;
         quicksort(x,first,j-1);
         quicksort(x,j+1,last);

    }
}

Output:
Enter size of the array: 5
Enter 5 elements: 3 8 0 1 2
Sorted elements: 0 1 2 3 8

It refers to the possibility for an investor to experience  losses due to  factors that affect the overall performance of the financial markets. Market risk cannot be eliminated through diversification, though it can be hedged against. The sources of market risk include natural disasters, recessions, political turmoil, changes in interest rates and terrorist attacks.

These days channel members are being accepted by companies as their partners. The intermediaries are even being asked to integrate their business with the companies which results in lesser costs, greater efficiency and improved customer service. Corporates like Airtel are adopting PRM (Partner relationship management) software to give that added advantage to their supply chain. They organise rewards and recognition programs for their channel partners and also organise proper channels though which partners can vent any of their grievances relating to payments, violation of codes etc.

The two broad categories of software in a computer are

1. System software
2. Application software

System software controls how the system works and enables user to access all of the system hardware and application software

The OS, utility programs and drivers come under system software.

Application software are software used by the user to perform specific task. They are installed according to the user's requirements.

The word processor, web browser, players, spreadsheets etc... come under this application software.

A redox reaction is a type of reaction which involves transfer of electrons among two species. This reaction is also called oxidation-reduction reaction.

In oxidation process, there is an increase in oxidation state of an atom, ion or molecule by losing the electrons.

In reduction process, there is a decrease in oxidation state of an atom, ion or molecule by accepting the electrons.

1)

In this reaction, Ba undergoes oxidation and Cl undergoes reduction.
This reaction is redox reaction.
In this reaction, oxidation number of Ba increases from 0 to +2 . So, Ba undergoes oxidation. The oxidation number of Cl decreases from 0 to -1. So, Cl undergoes reduction.

2) 

From this above reaction, it is clear that Aluminum undergoes oxidation and silver undergoes reduction.
Due to this, this reaction is redox reaction.

In this reaction, oxidation number of Aluminum increases from 0 to +1. So, aluminum undergoes oxidation. The oxidation number of silver decreases from +1 to 0. So, silver undergoes reduction.

3)

In this reaction, Mg undergoes oxidation and Br undergoes reduction.
This reaction is redox reaction.
The reactions 1, 3 and 4 are redox reactions.
In this reaction, oxidation number of Mg increases from 0 to +2 . So, Mg undergoes oxidation. The oxidation number of Br decreases from 0 to -1 . So, Br undergoes reduction.

Hence all the above reactions are redox reactions.

When an atom loses an electron it becomes a positive ion by acquiring negatively charged. When it loses electron, the atom's radius also decreased.
