Has always been a part of the right, I want to ask where is this code needs to be improved, thank you very much!

 # include & lt; stdio.h> 
Void sum (int n) 
{
Int sumn, t, I=0, num=1; 
While (sumn! Num)={
Num=sumn; 
Sumn=0; 
While (n!=0) {
T=n; 
T=t % 10; 
N=n/10; 
Sumn +=t; 
} 
Sumn=sumn * 3 + 1; 
N=sumn; 
I=I + 1; 
Printf (" % d: % d \ n ", I, sumn); 
} 
} 
Int main () 
{
int n; 
The scanf (" % d ", & amp; N); 
Getchar (); 
The sum (n); 
return 0; 
}

Where does the pta

I also do a do

Try to use your code

The first
Your sumn uninitialized, while the first execution (sumn!=sun) can be any value

The second
If the incoming n is 0, how will

CodePudding user response:

Oww, n=0, you already considered
See sumn initial value

CodePudding user response:

Buy the original poster is

I took half a day did not find

Should be sumn initialization, such as the pta is very high for this request
