Thread: program to find the range and average

hi.
i need to find the average and range of numbers entered by the user.
the user can enter as many terms as possible.
the user should enter a negative number to end.
i was able to do it with "goto".
but i need to do the program using if...else..
here's the code using "goto"

Code:

#include<stdio.h>
#include<conio.h>

int main()
 {
  int count;
  float value,high,low,sum,average,range;
  sum = 0;
  count = 0;
  printf("Enter numbers in a row\n.Enter negative number to end");
  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("\n\n");
	 printf("Total values : %d\n",count);
	 printf("Highest value : %f\nLowest value : %f\n",high,low);
	 printf("Range    : %f\nAverage  : %f\n",range,average);
	 return 0;
  }
