Java翻译成C, 请高手帮忙~~~感激不尽

拜托了, 大家~~~哪位高人帮助我一下吧

你给的就是错的
说说这个是干吗的？

照着改了下，不知道你想干什么的 所以。。。

#include <stdio.h>
#include <stdlib.h>

int main(void) {
int a[30];
int b[30];
int i;
int tot = 0;

a[0] = 1;
a[1] = 2;
a[2] = 3;

for(i=3; i<30; i++) {
a[i] = a[i-1] + a[i-2] + a[i-3];
}

for (i=0; i<30; i++) {
int temp;

printf("please input your %d number\n",i+1);
scanf("%d",&temp);
while (!check(temp, b, i)) {
scanf("%d",&temp);
}
b[i] = temp;

if (b[i] == 0) {
i = 30;
}
}

for (i = 0; i < 30; i++) {

if (b[i] == -1) {
b[i] = a[i];
printf("The missing number is: %d\n",b[i]);

}

if (b[i] == 0) {
tot = i;
i = 30;
}
