Question

Write three C programs that print out the max, min, and the average values of the

data file included below. Be sure to include the outputs of the programs in your

solutions. Use three data file structures that we have learned in chapter 3 (counter,

sentinel, and neither counter/sentinel). Also, draw three flowcharts for these three

programs.

130.5 120 140

140.4 140.8 150.2

140 -121 160.3

150 160.9 170

160.9 130.4 180

170 190.6 190

180 150.6 -110.5

-150 -110 120.1

150.1 170.7 130

190 180 170

Please include the results along with three flowcharts.

Explanation / Answer

#include <stdio.h>
int main()
{
FILE *sensor;
int num, min, max, sum, count, first;
sensor = fopen("F:data.txt", "r");
if (sensor != NULL)
{
for (sum = count = first = 0;
fscanf(sensor, "%d", &num) == 1; sum += num, ++count)
if (!first)
{
min = max = num; first = 1;
}
else if (num > max) max = num;
else if (num < min) min = num;
fclose(sensor);
printf("count = %d, min = %d, max = %d, sum = %d, avg = %.1lf ",
count, min, max, sum, sum / (double) count);
}
else
{
printf("Unable to read file 'F:data.txt'. " );
}
return 0;
}
