Codeblocks 20.3 和 minGW_x64_Win_Build 之间有什么问题?
What is Wrong between Codeblocks 20.3 and minGW_x64_Win_Build?
我在执行时遇到以下错误。我使用的编译器是 minGW_x64_Win_Build。位置、目录和一切都处于正确状态。
不知道,但这是内部错误。
||=== Build file: "no target" in "no project" (compiler: unknown) ===|

代码:
#include <iostream>
using namespace std;
void MainMenu();
void Decision(double, double);
int main()
{
MainMenu();
double userInput1;
double userInput2;
cout << " Enter Your Choice: " << '\n';
cin >> userInput1;
cout << " Enter Your Second Choice: " << '\n';
cin >> userInput2;
Decision(userInput2, userInput2);
return 0;
}
void MainMenu()
{
cout << " Enter Your choice" << '\n';
cout << " -----------------" << '\n';
cout << " 1 for Addition" << '\n';
cout << " 2 for Subtraction" << '\n';
cout << " 3 for Multiplication" << '\n';
cout << " 4 for Division" << '\n';
cout << " -----------------" <<'\n';
}
void Decision(double userInput1, double userInput2)
{
int R_usr;
switch (R_usr)
{
case 1:
cout << " The Result for the entered values: " << userInput1 << " and " << userInput2 << " is equal to: (" << userInput1 + userInput2 << ")" <<'\n';
break;
}
}
快照
编译器
您的 switch 语句检查了一个未初始化的变量。
问题已解决。
