Do (pre & post)Increment and decrement operators behave differently when printed in the same and different line in C++?

Before I explain anything,I would like you to run the following program.

void main()

{int j =10;

cout<<“j before increment =“<<j;

cout<<“++j =“<< ++j;

cout<<“ value of j after pre inc is “<<j;

cout<<“j++ = “<<j++;

cout<<“value of j after post  inc is “<<j;

j=10;

cout<< “lets try results if all are cascaded in same line”; // compplied right to left

cout<< “j=“<<j<“++j=”<<++j<<“j++=”<<j++;

}

 

It is interesting to note the output:

Output

j before increment 10

++j =11

value of j after pre inc is 11

j++ = 11

value of j after post  inc is 12

lets try results if all are cascaded in same line

j=12

++j= 12

j++= 10;

This is because the values are evaluted from right to left here and not left to right
