C program to calculate range of values and an average cost of a personal system.
Problem
A personal system is sold at different costs by the vendors.
Let’s take the list of costs (in hundreds) quoted by some vendors −
25.00, 30.50, 15.00, 28.25, 58.15,
37.00, 16.65, 42.00 68.45, 53.50
Solution
Calculate the average cost and range of values.
The difference between the highest and the lowest values in the series is called range Hence, Range = highest value - lowest value.
Now, find the highest and the lowest values in the series.
Example
Following is the C program to calculate the range of values and average cost of a personal system −
#include<stdio.h>
main(){
int count;
float value, high, low, sum, average, range;
sum = 0;
count = 0;
printf("enter no's in line and at end press any negative number
");
input:
scanf("%f", &value);
if (value < 0)
goto output;
count = count + 1;
if (count == 1)
high = low = value;
else if (value > high)
high = value;
else if (value < low)
low = value;
sum = sum + value;
goto input;
output:
average = sum/count;
range = high - low;
printf("
");
printf("Total values : %d
", count);
printf("Highest-value: %f
Lowest-value : %f
", high, low);
printf("Range : %f
Average : %f
", range, average);
}Output
When the above program is executed, it produces the following output −
Enter numbers in line and at end press any negative number 22.4 56.8 12.3 48.6 31.4 19.0 -1 Total values: 6 Highest-value: 56.799999 Lowest-value: 12.300000 Range: 44.500000 Average: 31.750000
