The c program is as follows :

Code
#include<stdio.h>
#include<conio.h>
 
void main()
{
 
int a[10],n=0,o=0,z=0,l;
clrscr();
 
printf("
Enter the number of digits in the given number : ");
scanf("%d",&l);
 
printf("
Enter the Binary number one by one: ");
 
for(i=0;i<l;i++)
{
scanf("%d",&a[i]);
}
 
for(i=0 ; i<l ;   i++)
{
n=a[i];
 
if(n==0)
o++;
 
else
z++;
 
}
 
printf("
The Number of Zeros is : %d",z);
 
printf("
The Number of Ones is : %d",o);
 
getch();
