Answer 1

i++ adds 1 and stores it in i, while i+1 just output value i by 1 more.

In general, "i" is not needed here ☺️:
int largestElement(int a[],int size){
static int larg;
if(a[size]>larg)
larg=a[size];
if(size>1)
largestElement(a,size-1);
return larg;
}

And don't forget about #include <stdio.h>

Answer 2

If you use ++i (pre-increment operator) it works. If you use i++ (post-increment operator), value of <i> is not modified until the current line is completely processed.

It's also great to understand the use case, where to use increment or decrement operator with a variable, and when to just add a value to a variable.

Do ++i

because i++ is post increment so 0, 0, 1, 2, 3
and on ++i , 0, 1, 2, 3
