求和编程可以通过多种方法实现,以下是几种常见的方法:
1. 使用C++编写
```cpp
include using namespace std; int main() { int n, shu, jihe = 0, ouhe = 0, i; cin >> n; for (i = 0; i < n; i++) { cin >> shu[i]; if (shu[i] % 2 == 0) { ouhe += shu[i]; } else { jihe += shu[i]; } } cout << "奇数之和: " << jihe << endl; cout << "偶数之和: " << ouhe << endl; return 0; } ``` 2. 使用VBA编写 方法一:使用字典求和 ```vba Sub dicSum() Dim dicA As Object Dim ArrKey, ArrItem Set dicA = CreateObject("Scripting.Dictionary") i = 2 Do Until Cells(i, 1).Text = "" dicA(Cells(i, 1).Text) = dicA(Cells(i, 1).Text) + Cells(i, 3).Value i = i + 1 Loop ArrKey = dicA.Keys ArrItem = dicA.Items [E2].Resize(dicA.Count, 1) = Application.Transpose(ArrKey) [F2].Resize(dicA.Count, 1) = Application.Transpose(ArrItem) Set dicA = Nothing End Sub ``` 方法二:使用自动求和公式 ```vba Sub 快速求和统计() Dim ws As Worksheet Dim 最后一行 As Long Set ws = ActiveSheet 最后一行 = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row For i = 1 To 10 If Application.WorksheetFunction.Count(ws.Range(ws.Cells(2, i), ws.Cells(最后一行, i))) > 0 Then ws.Cells(最后一行 + 1, i).Formula = "=SUM(" & ws.Cells(2, i).Address & ":" & ws.Cells(最后一行, i).Address & ")" ws.Cells(最后一行 + 1, i).Interior.Color = RGB(255, 255, 0) End If Next i MsgBox "统计完成啦!" End Sub ``` 3. 使用Excel公式 方法一:使用SUMIF函数 ```excel =SUMIF(A1:A10, ">1000", B1:B10) ``` 方法二:使用SUMIFS函数 ```excel =SUMIFS(C1:C10, A1:A10, ">1000", B1:B10, "北京") ``` 4. 使用递归求和(C语言) ```c include int sum(int n) { if (n == 0) { return 0; } else { return n + sum(n - 1); } } int main() { int n; printf("请输入一个整数n:"); scanf("%d", &n); printf("1到%d的和是: %d\n", n, sum(n)); return 0; } ``` 5. 使用循环求和(C语言) ```c include int main() { int n, i, sum = 0; printf("请输入一个整数n:"); scanf("%d", &n); for (i = 1; i <= n; i++) { sum += i; } printf("1到%d的和是: %d\n", n, sum); return 0; } ``` 这些方法涵盖了从基本的循环求和到使用高级函数和VBA宏的复杂求和场景。根据具体需求和编程环境,可以选择合适的方法进行实现。
