Thank you for your help !

Hi. I have assignment to find difference between Min and Max of an array of 5 numbers. I did some work, but after compiling - my program does not run, it just stops working.. Can you help me, where is my mistake ? Array values needs to be double.

#include #include int main()
{
int i; // element in array
int size; // size of array
double array [i]; // number of elements in array
double min; //minimum value
double max; // maximum value
double difference; // difference between maximum and minimum values

printf("Enter the size of the array: ");
scanf("%d",&size);
printf("Enter %d elements in to the array: ", size);
scanf("%d",&array[i]);

max = array[0]; // let first number in array be maximum
for (i=0; iarray[i])
min = array [i];
{
printf("Minimum value is: %d\n",min);
}

difference = max - min;

printf ("Difference between Min and Max values is %d\n", difference);

/* if (i>= 5)
{
printf ("Only 5 numbers allowed. \n");
break;
}
*/

system("PAUSE");
return 0;
}

thank you everybody for help. I will keep working on it. my teacher is not helping, so I am on my own..

i dont really know how to do that yet... Ok, i will try.. is there a general format of that function somewhere?

I am student, taking C programming now. I have assignment to write function to check if inputed data is numbers. if not - it should write that, and ask to enter number again. I wrote code, to write error message, but dont know how to make program to work on next input.. should I call the Main function again ? int main() { double hours; //hours worked in a week double payrate; // hourly salary double grosspay; //total weekly payment int k; //number of values read printf ("Enter number of hours, and hourly pay (or press 0 to exit) \n"); while ((k = scanf ("%lf%lf", &hours, &payrate))==2) { if (isdigit(hours) !=0) return hours; else printf ("You entered invalid data, please enter number of hours \n"); if (isdigit(payrate) !=0) return payrate; else printf ("You entered invalid data, please enter payrate \n"); if (hours==0 || payrate==0) { printf ("Good Bye. \n\n"); system("PAUSE"); return 0; } double grosspay; grosspay = calculateGrossPay(hours, payrate); printf ("Hours worked: %.2f\n", hours); printf ("Hourly Rate: %.2f\n\n", payrate); printf ("Your weekly payment is: $ %.2f \n\n\n", grosspay);
