能不能换一个声明，为什么?
程序代码：#include<stdio.h>
int main ()
{
long num;
long sum=0L;
int status;
printf("Please enter an integer to be summed.");
printf("(q to quit):");
status = scanf("%ld",&num);
while (status == 1)
{
sum = sum +num;
printf ("Please enter next integer (q to quit):");
status = scanf("%ld",&num);
}
printf("Those integers sum to %ld.\n",sum);
return 0;
}程序代码：#include<stdio.h>
int main ()
{
long num;
long sum=0L;
_Bool input_is_good;
printf("Please enter an integer to be summed.");
printf("(q to quit):");
input_is_good = (scanf("%ld",&num)==1);
while (input_is_good)
{
sum = sum +num;
printf ("Please enter next integer (q to quit):");
input_is_good = (scanf("%ld",&num)==1);
}
printf("Those integers sum to %ld.\n",sum);
return 0;
}假设两个程序都可以运行，那能不能把_Bool换成int，为什么不行，不都是1或0吗
