something in my array is giving me a few errors

Explanation / Answer
Listed below may be the causes of a few of your errors:
1. When you declare local variables i and j, such that,
int i,j=0,
only j is 0, i remains undefined, which means it has no value.
You should rewrite this as int i=0,j=0;
2. Inside some methods, you have used multiple for loops. But you have initialized i=0 only before beginning of first for loop. This may lead to loop reading wrong array values as i may be wrong. To prevent this, either initialize i=0 before each loop, or use:
for(int i=0; i<size;i++) instead of just for(i;i<size;I++).
Hopefully all your errors should be rectified once you correct these 2 things everywhere in your code. If some errors remain, reach out to me in comments. Please upvote if you found this helpful.
