Hi can anyone help about this i am getting a logical error in the program

#include<stdio.h>
#include<conio.h>
void quicksort(int a[],int lb,int ub);
void partitionarray(int a[],int lb,int ub,int loc);
void main()
{
int a[100],n,i,lb,ub;
printf("how many elements");
scanf("%d",&n);
for(i=0;i<n;i++)
{
printf("enter %dth",i+1);
scanf("%d",&a);
}
quicksort(a,lb,ub);
for(i=lb;i<ub+1;i++)
printf("sorted array is");
for(i=0;i<n;i++)
{
printf("%d\t",a);
}
getch();
clrscr();
}
void quicksort(int a[],int lb,int ub)
{
int loc,n;
//for(n=lb;n<ub;n++)

if(lb<ub)
{
partitionarray(a,lb,ub,loc);
quicksort(a,lb,loc-1);
quicksort(a,loc+1,ub);
}
}
void partitionarray(int a[],int lb,int ub,int loc)
{
int left,right,temp;
int done;
left=lb;
right=ub;
loc=lb;
done=0;
while(!done)
{
while((a[loc]<=a

)&&(loc!=right))
{
right=right-1;
}
if(loc=right)
{
done=1;

}
else if (a[loc]>a

)
{
temp=a

;
a

=a[loc];
a[loc]=temp;
loc=right;
}
if(!done)
{
while((a[loc]>=a

)&&(loc!=left))
left=left+1;
}
if(loc=left)
{
done=1;
}
else if(a[loc]<a

)
{
temp=a

;
a

=a[loc];
a[loc]=temp;
loc=left;
}
}
