题目分析:
将输入数据存到数组中,设置一个标志位temp判断是否找到数据。
源代码:
#include <iostream> using namespace std; int main() { int n; while (cin>>n) { int a[210] = {0}; int x; int temp = -1; for (int i = 0; i < n; i ++) { cin>>a[i]; } cin>>x; for (int j = 0; j < n; j ++) { if (x == a[j]) { temp = j; cout<<temp<<endl; } } if (temp == -1) { cout<<"-1"<<endl; } } return 0; }
