Please help me out. I am not able to get output for my quick sort programe. Code is given below

```
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
void merge(int arr[],int minm,int mid,int maxm)
{int i,j,l;
int t[maxm];
for(i=0,j=mid,l=0;i<mid||j<maxm;)
{
if(arr[i]<=arr[j])
{t[l]=arr[i];
l++;
i++;}
else
{t[l]=arr[j];
l++;
j++;}
}
if(i==mid)
for(;j<maxm;)
{
t[l]=arr[j];
l++;
j++;
}
if(j==maxm)
for(;i<maxm;)
{
t[l]=arr[i];
l++;
i++;
}
for(i=0;i<maxm;i++)
arr[i]=t[i];
}
void mergesort(int a[],int p,int n)
{int mid;
if(p<n)
{mid=(p+n)/2;
mergesort(a,p,mid);
mergesort(a,mid,n);
merge(a,p,mid,n);}
}
int main()
{int n,j;
printf("Enter the value of n");
scanf("%d",&n);
int a[n];
for(j=0;j<n;j++)
{ printf("Enter the value of n %d",j);
scanf("%d",&a[j]);
}
mergesort(a,0,n);
for(j=0;j<n;j++)
{ printf("The value of n %d is %d",j,a[j]);
}
return 1;
}
```
