#include <iostream>

int main()
{
    std::cout << "Nerdrvox skzbnakan gumar = ";
    double invmoney = 0;
    std::cin >> invmoney;
    std::cout << std::endl << "Nerdrvox skzbnakan gumar = " << invmoney;
    std::cout << std::endl << "Qani tarov = ";
    int years = 0;
    std::cin >> years;
    std::cout << std::endl << "Qani tarov = " << years;

    /*
     * After this point the cmd says press any key to continue, after pressinga key
     * cmd closes. However it is supposed to do this.
     */

    double summary = invmoney;

    int months = 12 * years;
    for (int i = months; i < 0; i--)
    {
        std::cout << "Month " << i - months << std::endl << "Invested money"
                << summary << std::endl;
        double percent = summary * 0.1;
        std::cout << "Add percent" << percent << std::endl;
        summary += percent;
        std::cout << "Sum for month " << i - months << "is " << summary;
    }

    return 0;
}

您能告诉我原因以及如何解决吗？

最佳答案

是的，这是因为您的for循环未执行。

for (int i = months; i<0; i--)

需要是

for (int i = months; i>0; i--)

for具有以下结构：

for (initialization; condition; increase) statement;

只要condition为true，for循环将继续执行。在您的原始示例中，将i设置为months，这取决于您的输入，将大于或等于零。这将使条件i<0为假，这将完全跳过循环。
