Script

#include <stdio.h>

main()
{
int number_of_numbers, count = 1;
float takeinput, average, total = 0;

printf("\n\nHow many numbers will you type in ? : ");
scanf("%d", &number_of_numbers);

do
{
printf("Enter a number: ");
scanf("%f", &takeinput);
total = total + takeinput;
count = count + 1;
}
while (count <= number_of_numbers);

average = total/number_of_numbers;
printf("\nThe average of all these numbers is: %.2f", average);
printf("\n\n");
}
