Comment on Tutorial : Increment and Decrement Operator By aathishankaran
Answer for Comment 4 :
" n=n++ ; " is a useless line !! it doesn't do anything. what's actually happening there is, that the value of n was assigned 0, So, when you run the loop the value of n++ gets stored in n (as we had n=n++) which is 0 (as a post increment operator first reads the value then increments 1to it). So the value of n++ is 0 which is being stored by n . *output comes 0 for the first loop and as following by all other loops output is 0 till the end*
In simple way !!
int n=0;
for(int m=0 ; m<5 ; m++){
n=n++ //n++ == 0 at this time so, n becomes 0
}
To avoid this useless thing instead of using
n=n++;
use
n++; //This would add 1 in each loop :)
Thank you . I hope now you don't have any doubt on "n=n++;" ;)
