O god! O (n)=a + aa + s aaa +,,,, + a.. + aa values, which is a number for a look at where I went wrong? No errors, but a run it is' s' undefined???????

CodePudding user response:

Should is not initialized, and s=0;

Instead of int s=0 also not ah

CodePudding user response:

A values
Cycle the first sentence is
T=a;
Constantly reset t
Equal to the number you've been with the same

CodePudding user response:

How that s not defined...

CodePudding user response:

reference lin5161678 reply: 3/f

a values
Cycle the first sentence is
T=a;
Constantly reset t
Equal to the number you've been with the same

The while loop inside the first sentence is not I use the t=a?
