Sum of 'n' positive numbers


Write a C program to that allows the user to enter 'n' numbers and finds the number of positive numbers entered and the sum of all positive numbers entered using a while loop.

Input Format:
Input consists of n+1 integers. The first integer corresponds to n. The next n integers correspond to the numbers to be added. Consider 0 to be a positive number.

Output Format: 
Refer Sample Input and Output for formatting specifications.

[All text in bold corresponds to input and the rest corresponds to output]

Sample Input and Output: 
Enter the value of n
4
Enter the number
5
Enter the number
-2
Enter the number
-1
Enter the number
6
Number of positive numbers entered is 2 and the sum is 11

Code:
  #include<stdio.h>
int main(){
  int n,sum=0,count=0,i=1,b;
  printf("Enter the value of n\n");
  scanf("%d",&n);
  while(i<=n)
  {
    printf("Enter the number\n");
    scanf("%d",&b);
    i++;
    if(b>=0)
    {
      count++;
      sum=sum+b;
    }
  }
  printf("Number of positive numbers entered is %d and the sum is %d",count,sum);
  return 0;
}
