code description - This code runs on the logic of while looping. the loop will take input and then store it into one variable until -1 is hit. it will also keep adding and storing the variable into a seprate variable s
if only 1 variable is entered the code will exit displaying 0 , if more than 2 it will display 1.

 int sum=0;

 scanf("%d", &prev);

if (prev != -1)  // if the first number is -1 we will exit the loop
{
  sum = 1;
 
    scanf("%d", &curr);
   
 while (curr != -1)  // again if the 2nd number is -1 we will exit the loop
