Why turned negative input after 11, already defined num for long ah, ask good intention person to help me this dish chicken

Long int the maximum is 2147483647

Why always output after I use the long long 12 digits, and each number only and is not correct

Why always output after I use the long long 12 digits, and you only and don't correct

You put the source code, I give it a try

You put the source code, I try

#include
#include
#include
Int main ()
{
Int sum=0, count=0;
Long long num.
Printf (" please enter a number: ");
The scanf (" % l64d ", & amp; Num);
Do {
If (num<0)
{
Printf (" please enter a number greater than 0: ");
The scanf (" % l64d ", & amp; Num);
}
} while (num<0);

While (num!=0)
{
The sum +=num % 10;
Num/=10;
count++;
}
Printf (" digit % d, the sum of the number of you is % d, \ n ", count, sum);
}

Try this

 # include & lt; stdio.h> 
Int main () 
{
Int sum=0; 
int count=0; 
Long long int num. 
Printf (" please enter a number: "); 
The scanf (" % LLD, & amp; Num); 
Do {
If (num<0) 
{
Printf (" please enter a number greater than 0: "); 
The scanf (" % LLD, & amp; Num); 
} 
} while (num<0); 


While (num!=0) 
{
The sum +=num % 10; 
Num/=10; 
count++; 
} 
Printf (" digit % d, the sum of the number of you is % d, \ n ", count, sum); 
}

What is % l64d operation

Ok thank you very much

Now do not have what problem

CodePudding user response:

Crossing the line, beyond the long int said the scope of the,

Suggest using string is more appropriate,

 # include & lt; stdio.h> 
#include  
#include  

Int main (void) 
{
Char STR [32]. 
Int ret, len, sum=0, I; 

Printf (" please enter a number: "); 
Ret=the scanf (" % s ", STR); 

While (ret & amp; & STR [0]=='-') {
Printf (" please enter a number greater than 0: "); 
Ret=the scanf (" % s ", STR); 
} 
Do {
Len=strlen (STR); 
i=0; 
While (STR) [I] {
The sum +=STR [i++] - '0'; 
} 
If (sum==0) {
Printf (" please enter a number greater than 0: "); 
Ret=the scanf (" % s ", STR); 
} 
} while (sum==0); 


: printf (" % d, the sum of the number of you is % d \ n ", len, sum); 

return 0; 
}

For your reference ~

To begin with 0 Numbers, there will be a problem, suggestion perfecting it
