Explain recursive function. Write a program to find the GCD of a number by using recursive function. 

Predict output of following program segment.
main()
{
int a,b,*p1,*p2,x,y;
clrscr();
a=48;b=10;p1=&a;p2=&b;
x=*p1**p2-8;
*p1=*p1+*p2;
y=(*p1/ *p2)+20;
printf("%d%d%d%d%d%d",*p1,*p2,a,b,x,y);
}

Predict output of following program segment.

main()
{
int x=4, y=9,z;
clrscr();
z=x++ + --y+y;
printf("\n%d%d%d",x,y,z);
z= --x+x+y--;
printf("\n%d%d%d",x,y,z);
getch();
}
