在c语言中怎么输入一组数字存储在数组里

#define N 100
int main()
{
int iarray[100];
int num;

for(int i = 0; i < N; i++)
{
iarray[i] = i*2;
}

printf("请输入一个数字：");
scanf("%d", &num);

int first = 0;
int last = N-1;
int half = 0;
bool bfind = false;

time_t start, end;
start = time(NULL);

do
{
half = (first+last)/2;;
if( num == iarray[half])
{
bfind = true;
break;
}
else if( num > iarray[half])
{
first = half + 1;
}
else
{
last = half - 1;
}

} while( first <= last );

end = time(NULL);

if(bfind)
{
printf("num = %d,pos = %d\n",num, half);
}
else
{
printf("not found!\n");
}
printf("endtime = %d, starttime = %d\n", end, start);

printf("使用的时间为：%.16f\n", (double)(end - start)/CLOCKS_PER_SEC);

system("pause");
return 1;
}
