To swap elements i and j within the same int array a;
Code:int temp = a[i];
a[i] = a[j];
a[j] = temp;
can u explain to me the code cuz i didnt understand it
No, sorry!
You seem to first must learn the basics of mathematics, logic and algorithms
and only after that - go on with basics of programming. :cool:
int temp = a[i];Quote:

He has created an integer variable called "temp" and assigned the value of a[i] to it. Then his has assigned the value of a[j] to a[i]. Finally, he assigned the value of a[i] (which was assigned to temp earlier) and assigned it to a[j].
a[i] goes into 'temp', a[j] goes into a[i], and temp goes into a[j]. Simple enough.
