这个错误提示表明在运行时发生了有符号整数溢出。根据错误提示，是因为将一个较大的整数加上5导致了溢出。
要解决这个问题，可以考虑使用更大的数据类型来存储计算结果，例如使用long long代替int。
以下是修改后的示例代码：
#include <iostream>
int main() {
int mainTank = 10; // 假设初始值为10
int additionalTank = 3; // 假设初始值为3
long long num = 0; // 使用long long数据类型
while (mainTank > 5 || additionalTank != 0) {
num += 5;
mainTank -= 5;
additionalTank -= 1;
}
num = num + mainTank;
num *= 10;
std::cout << "Result: " << num << std::endl;
return 0;
}
通过使用long long数据类型来存储计算结果，可以避免溢出错误。请注意，需要根据实际情况确定mainTank和additionalTank的初始值，并做相应的调整。
