Thread: Array problem

Notice that you call scanf twice on each iteration. Fix it to call scanf once per iteration. Also, I suggest that you check i < MAX before scanf.

gosh, but that code looks familiar! Anyway:

Loop 101, here:

Code:

    while ( (scanf("%d", &array[i]) == 1) && (i<MAX) ) {
        scanf("%d", &array[i]);  //there's an echo around here!
        i++;
    }

//what is the value of i, right here?
    
    while (i>=0) {
        printf("%d ", array[i]);  //i is one number too high, and out of bounds
        i--;                           //on the first time thru this loop 
    }

To fix the i problem:

Code:

    while (i>0) {  //change the test condition, just a bit by removing the =
        printf("%d ", array[--i]);  //decrement i first, before you access arra[i]
        //i--;     <===== don't need this anymore 
    }

Loops that have a comparison test, will run one number past the stop test point. Say you were looping from 0 to 9, in a for loop:

Code:

for(i=0;i<10;i++) {
  printf("%d", i);
}
printf("%d", i); //10 will be printed here, not 9

Try that out.
