Simple but many of the people aren't aware of it.

Difference between i++ and ++i

Most of us struggle with these two while finding the output of C/C++ programs.

i++ works follows:

First the value of i will be used and the value will be incremented 

i=1;
j=i++;
ans:i=2,j=1.


In case of ++i:

The value of i will be increased first then it'll be used.

i=1;
j=++i;
ans:i=2,j=2.

Hope all the above information will be helpful for the beginners as well as for the people who have struggled with the pre-increment and post-increment process in C.
