高手们 超级菜鸟来请教问题了 请问能不能让下面这个“密码”函数（的一部分）实现输入三次密码 如果不行的话 才执行printf语句 而在三次以内输入错误的话就输出“请重新输入”
void changepassword()
{
printf("please enter your password: \n");
static int n=1234;int t,k;
scanf("%d",&k);[K是密码]
if(k!=n)
{
printf(" sorry! the password is worng!the serves has stop!\n");exit(0);
}
void changepassword()
{
printf("please enter your password: \n");
static int n=1234;int t,k;
scanf("%d",&k);[K是密码]
if(k!=n)
{
printf(" sorry! the password is worng!the serves has stop!\n");exit(0);
}
void changepassword()
{
printf("please enter your password: \n");
static int n=1234;int t,k;
for ( t = 0; t < 3; t++ )
{
scanf("%d",&k);[K是密码]
if(k==n)
{
break;
}
printf( "retry:" );
}
if ( t == 3 )
{
printf(" sorry! the password is worng!the serves has stop!\n");exit(0);
}
}
n赋值为3,k＝0,进行++k，当k<=n时，循环结束。
