c++程序填空求大佬帮忙

#include
#define itemNum(a) _____________________________
//顺序查找模板函数：在T类型的数组中查找值val
//返回true(找到)或false(没有找到)

int main() {
int a1[]={12,80,78,62,63,89,5,9,89,23,1,6,33,54,30,97,55};
double a2[]={1.2,8.,7.8,6.2,8.9,0.9,8.9,2.3,.1,3.3,5.4,3.0,9.7};

return 0;

}
输入
第1行：一批空格分隔的正整数，用-1结束 第2行：一批空格分隔的双精度数
输出
第1行：0和1组成的串(正整数值在整数数组中存在输出1，否则输出0) 第2行：0和1组成的串(双精度数值在双精度数组中存在输出1，否则输出0)
输入样例 1
12 34 44 56 89 33 -1

1.0 1.2 8.9 0.1 3.0 5.6
