Count positives and calculate their average from 5 inputs
Count positives and calculate their average from 5 inputs
Write a C program that reads 5 numbers, counts the number of positive numbers, and prints out the average of all positive values.
Pictorial Presentation:
C Code:
#include <stdio.h>
int main() {
float numbers[5], total=0, avg; // Declare an array to store 5 numbers, and variables for total and average
int j, pctr=0; // Declare variables for loop counter and positive count
// Prompt user for five numbers and store them in the array
printf("\nInput the first number: ");
scanf("%f", &numbers[0]);
printf("\nInput the second number: ");
scanf("%f", &numbers[1]);
printf("\nInput the third number: ");
scanf("%f", &numbers[2]);
printf("\nInput the fourth number: ");
scanf("%f", &numbers[3]);
printf("\nInput the fifth number: ");
scanf("%f", &numbers[4]);
for(j = 0; j < 5; j++) {
if(numbers[j] > 0) // Check if the number is positive
{
pctr++; // Increment positive count
total += numbers[j]; // Add positive number to total
}
}
avg = total/pctr; // Calculate average of positive numbers
// Print the counts of positive numbers and the average
printf("\nNumber of positive numbers: %d", pctr);
printf("\nAverage value of the said positive numbers: %.2f", avg);
printf("\n");
return 0;
}
Sample Output:
Input the first number: 5
Input the second number: 8
Input the third number: 10
Input the fourth number: -5
Input the fifth number: 25
Number of positive numbers: 4
Average value of the said positive numbers: 12.00
