#include "stdio.h"

int main(void)
{

int order, nextp, N=3;
char cont;
nextp = 0;
printf("\nShould we continue (y or n): ");
scanf("%c", &cont);
if (cont != 'y') return;
for(; nextp < N; nextp++)
{
printf("Enter order number: ");
scanf("%d", &order);
printf("you have entered %d\n", order);
printf("okay now continue with cont\n");


printf("enter cont y or n: ");
scanf("%c", &cont);
if (cont != 'y')
{
printf("\nnot equal to y\n");
break;
}
printf("after intepreting t[0]");
}

return 0;
}

输出看起来像这样

Should we continue (y or n): y
Enter order number: 45
you have entered 45
okay now continue with cont
enter cont y or n:
not equal to y

第二个输入被跳过。为什么?
