C Exercises: Display the number of positive values, the minimum value, the maximum value and the average of all numbers

C Basic Declarations and Expressions: Exercise-64 with Solution

Write a C program that accepts integers from the user until a zero or a negative number, display the number of positive values, the minimum value, the maximum value and the average of all numbers.

Test data and expected output:
5 2 5 8 9 12 0

Sample Solution:

C Code:

#include <stdio.h>
  int main() {
    int a, ctr = 0, min_num, max_num, s = 0;
    double avg;
    printf("Input a positive integer:\n");
    scanf("%d", &a);
    if (a <= 0) 
    {
      printf("No positive number entered\n");
      return 0;
    }
    min_num = a;
    max_num = a;
    while (a > 0) {
      s += a;
      ctr++;
      max_num = a > max_num ? a : max_num;
      min_num = a < min_num ? a : min_num;
      printf("Input next positive integer:\n");
      scanf("%d", &a);
    }
    avg = s / (double) ctr;
    printf("Number of positive values entered is %d\n", ctr);
    printf("Maximum value entered is %d\n", max_num);
    printf("Minimum value entered is %d\n", min_num);
    printf("Average value is %0.4lf\n", avg);
    return 0;
  }

Sample Output:

Input a positive integer:
Input next positive integer: 15
Input next positive integer: 25
Input next positive integer: 37
Input next positive integer: 43
Number of positive values entered is 4
Maximum value entered is 43
Minimum value entered is 15
Average value is 30.0000

Previous:Write a C program that accepts a positive integer n less than 100 from the user and prints out the sum 1⁴ + 2⁴ + 4⁴ + 7⁴ + 11⁴ + • • • + m⁴ , where m is less than or equal to n. Print appropriate message.
Next: Write a C program that prints out the prime numbers between 1 and 200. The output should be such that each row contains a maximum of 20 prime numbers.
