Question

Assume that, for a given town, mid-day daily temperature in Fahrenheit was measured for a month and stored in a file called temperature.txt. Write a complete C Language program that reads the stored temperatures, one at a time, from the file temperature.txt and converts the read temperature to its equivalent in Celsius. Your program should store each converted temperature in an output file called results.txt. Your program should find the average, the minimum, and the maximum temperatures in Celsius and save the results in the output file. Use data type double for input and output temperatures.

Answer 1

Here is the answer for you, a like would be helpful..

C Code:

#include <stdio.h>

void main()
{
    FILE *input, *output;
    double f, cel, small = 0, large = 0, avg = 0, sum = 0;
    int count = 0, flag = 0;
    input = fopen("temperature.txt", "r");
    output = fopen("results.txt", "wb");
    if (input == NULL)
    {
        printf("Can't open the input.");
    }
    else
    {
        do
        {
            count++;
            fscanf(input, "%lf", &f);
            cel = ((f - 32) * 5 / 9);
            if (flag == 0)
            {
                large = cel;
                small = cel;
                flag++;
            }
            else
            {
                if (cel < small)
                    small = cel;
                if (cel > large)
                    large = cel;
            }
            sum = sum + cel;
            avg = sum / count;
            fprintf(output, "%lf\n", cel);
        } while (!feof(input));
    }
    fprintf(output, "Small: %lf\n", small);
    fprintf(output, "Large: %lf\n", large);
    fprintf(output, "Average: %lf\n", avg);
}
