獲取新陣列中的隨機值

Question

我正在從數組中創建一個新數組。並且我得到了隨機值（類似-858993460）這是我的代碼

#include<iostream> 
using namespace std; 
int main() { 
    const int m = 8; 
     int i, k; 
     int A[m] = { 1,2,3,4,5,6,7,8 }; 
    int B[m]; 
    k = 0; 
    for (i = 0; i < m; i++) { 
     if (A[i] % 2 == 0) { 
      A[i] = B[i]; 
      k = k + 1; 
     } 
    } 
    for (i = 0; i < k; i++) { 
     cout << B[k]; 
    } 
    cout << endl; 
    return 0; 
}

可能是你想要的。

#include<iostream> 
using namespace std; 
int main() { 
    const int m = 8; 
    int i, k; 
    int A[m] = { 1,2,3,4,5,6,7,8 }; 
    int B[m]; 
    k = 0; 
    for (i = 0; i < m; i++) { 
     if (A[i] % 2 == 0) { 
      B[k] = A[i]; 
      k = k + 1; 
     } 
    } 
    for (i = 0; i < k; i++) { 
     cout << B[i]; 
    } 
    cout << endl; 
    return 0; 
}
