Why it is giving infinity loop when i write i=i++ ? but when i write i = ++i . It work well .
Is it right to use ++i ? Why i++ giving infinity loop ? https://code.sololearn.com/c4JVhs76s2pC/?ref=app

G'day Abhay mishra you didn't say that the infinite loop is at i=0.... That makes much more sense.
The common use for var++ is to add 1 to the variable that is the increment counter for the loop.
var++ is practically the same as var=var+1
The difference is that var++ increases according to the compilers order of code execution, (which will be unpredictable between different systems or undefined)
++var is also equivalent to var=var+1
The order of execution of ++var is much more predictable, it always increments before being used in that line of code.
TLDR: you have confused the system with postfix as well as definition in the same line of code. Change 👎i=i++; to be 👍i++;

Because ++i is known as prefix while i++ is postfix.
