运行我的程序时出现运行时错误

Question

My code is to get the num of digits for any integer up to 1000000 at most. This is my code either using while or for or if :

#include <stdio.h>
#include <stdlib.h>
#include <math.h> 
int main() {
  int t,num_of_seven_segment=0;

  printf("Enter test case: ");

  scanf("%d", &t);`

 /* for(;t!=0;t=t/10)
  {
        if(t>=1000001)
break; 
      num_of_seven_segment++;
  }*/

  while(t!=0)
{
    t=t/10;
    num_of_seven_segment++;

  }
   printf(" %d",num_of_seven_segment);
   getch();

}

#include <stdio.h>

#include <stdlib.h>

#include <math.h>

int main()


{

int t;



int num_of_sevensegment=0;



printf("enter test cases");



scanf("%d",&t);




if(t<1000000)



num_of_sevensegment+=6;




 if (t<100000)



num_of_sevensegment--;




 if (t<10000)



num_of_sevensegment--;



 if (t<1000)



num_of_sevensegment--;


 if (t<100)


num_of_sevensegment--;



 if (t<10)



num_of_sevensegment--;



else if(t==1000000)



num_of_sevensegment=7;




printf("%d",num_of_sevensegment);




return 0;


}

Answer 1

Since you are using an online judge, I would say that adding a return 0; statement at the end of the first code should fix it. getch() doesn't usually work.

Additionally (not really related to the runtime error), I don't think explicitly prompting the user for input is required in online judges.

Also, in the statement - printf(" %d",num_of_seven_segment); there seems to be an extra space before %d - a possible source of wrong answer.
