 Finding the minimum number of a txt file of numbers using input redirection I have the program working but the minimum part doesn't work.
It gives me zero for the minimum.
Here is my code.
I hope you guys could help me.
Any help will be appreciated.
#include <stdio.h>
int main()
{
float avg = 0,min = 0,max = 0,t=0,sum = 0;
int count=0,counter=0,num=0,cold=0;
while (scanf("%f",&t)==1){
/*If statement for finding the maximum Temperature.Displays the Maximum
Tempurature */
if (max<t)
max =t;
printf("The Maximum Temperature is: %.0f\n", max);
/*If statement to count the number of temperatures over 85.Displays the
number of hot days*/
if(t>=85)
num++;
printf("The number of hot days are:%d\n",num);
/*Display the Minimum Temperature*/
if (t<min)
min=t;
printf("The Minimum Temperature is: %.0f\n", min);
/*If statement to count Temperature between 60 an 84.Display the number of
pleasant days */
if(t>=60 && t<=84)
count++;
printf("The number of pleasant days:%d\n",count);
/*If statement to count the number of cold days. Display the number of cold
days*/
if(t<=60)
cold=cold+1;
printf("The number of cold days:%d\n",cold);
/*Add all the Temperatures together and counts the number of temperatures
and Desplays the
Average of list of the Temperatures*/
sum+=t;
counter=counter+1;
avg=sum/counter;
printf("Average of the Temperatures is:%2.0f\n\n",avg);
Quote: }
return 0;
}

You set the minimum to zero. Fixing this is left as an exercise for the
reader. Also, if all values are negative max will be 0.

Let us start by removing most of the vertical space and the
silliest comments. This lets the result appear more or less on a
single screen:

> if(t>=85)
> num++;
> printf("The number of hot days are:%d\n",num);
> if (t<min)
> min=t;
> printf("The Minimum Temperature is: %.0f\n", min);
> if(t>=60 && t<=84)
> count++;
> printf("The number of pleasant days:%d\n",count);
> if(t<=60)
> cold=cold+1;
> printf("The number of cold days:%d\n",cold);
> sum+=t;
> counter=counter+1;

make it semi-legible:

initialization of "min = 0" and the following statement, all found
by searching for use of the word "min":
Quote: > if (t < min)
> min = t;
and realize that to alter min we have to enter a value less than
0. Maybe we should initialize min to something different. Let's
try 1000. In fact, let's also declare one initialized item per
line. We also change the name "count" to "pleasant" and "num" to
"hot" throughout in order to reflect their purpose. I also put
back the occasional blank line to separate distinct groups of
statements.
Quote: > int main(void) /* and add this "void" for good measure */
> {
> float avg = 0,
min = 1000,
max = 0,
t = 0,
sum = 0;
Quote: > int pleasant = 0,
counter = 0,
hot = 0,
cold = 0;
Quote: > while (scanf("%f", &t) == 1) {

more readable. Conclusions: Keep names meaningful, and formatting
consistent and accurate. Don't squander vertical space. Do not
conserve horizontal blanks around operators. Neatness counts. I
would also advise using more parentheses in logical statements, to
make things perfectly clear, i.e. "if ((t >= 60) && (t <= 84))".
If you don't get in the habit something will bite you sooner or
later.
Actually your initial effort was pretty good, for a tyro. You
actually checked the result from scanf properly, and declared main
almost correctly.
