C program to find the arithmetic mean of n numbers

Write a function to find the arithmetic mean of n numbers. (pass an array
to a function).
Function prototype : float amean(flaot x[], int n)

#include

void main()
{
float a[30],am;
int n,i,j;
float amean(float [],int);
clrscr();
printf("How Many Numbers For Arithmetic Mean==");
scanf("%d",&n);
printf("\nEnter %d Numbers\n",n);
for(i=0;i scanf("%f",&a[i]);
am=amean(a,n);
printf("\nArithmetic Mean of %d Numbers==%f",n,am);
getch();
}
float amean(float *a,int n)
{
float am=0;
int i;
for(i=0;i {
am=am+*(a+i);
}
am=am/n;
return am;
}
/* Output
How Many Numbers For Arithmetic Mean==6

Enter 6 Numbers
