A program to determine the range of values and the average cost of a personal computer (P.C.) in the market.

#include

main()

{ int count=0;

float value, high, low, sum=0, average, range;

clrscr();

printf("Enter numbers in a line: input a NEGAATIVE number to end\n");

input:

scanf("%f",&value);

if(value<0)

goto output;

count+=1;

if(count==1)

high=low=value;

else if(value>high)

high=value;

else if(value

low=value;

sum+=value;

goto input;

output:

average=sum/count;

range=high-low;

printf(“\n\n”);

printf(“Total values: %d\n”, count);

printf("Highest-value: %f\n Lowest-value: %f\n”, high, low);

printf(“Range : %f\nAverage : %f\n”, range, average);

getch();
