//Hello,
//if say I create a list if a 100 values in this way
int list [100];
// then assign the first value of the list in this way
list[0]=10;//IS THIS CORRECT FOR ADDING A VALUE INTO AN ARRAY????
//then run a For loop from i=1 to say less than 100,generate and add value to list from index 1 to 99.
/* The list from 1 to 99 works , what I cannot figure out is if the index 0 value of 10 is added in the list[100] of or a separate list of list[0] size was created.*/
