Answer 1

What exactly?
If output, then this is explanation of output:
1) adding 1 to 0, printing "1";
2) adding 2 to 1, printing "3";
3) adding 3 to 3, printing "6";
4) adding 4 to 6, printing "10";
5) adding 5 to 10, printing "15";
6) adding 6 to 15, printing "21";
7) adding 7 to 21, printing "28";
8) adding 8 to 28, printing "36".
Final output: "1361015212836" ("1" + "3" + "6" + "10" + "15" + "21" + "28" + "36").
Note: try placing `cout<<x;` outside the "for" curly brackets to print only the final value (36).

Answer 2

Shubham Dhyani , as the output expression is placed inside the for loop, it will be executed in each iteration.

BTW, your description of ".. why this code is not working? ..." does not really help, because this can mean anything.
