C++ C++;控制台问题
这似乎是一个简单的问题,但我不知道是什么让我的控制台快速打开和关闭?我在main()函数中包含了系统(“暂停”) 节目信息: 该程序用于电影院票务系统,显示哪一排的座位可用(如多维数组所示) 有人知道为什么控制台不能打开吗?我在编译器中没有收到任何错误消息C++ C++;控制台问题,c++,arrays,function,multidimensional-array,C++,Arrays,Function,Multidimensional Array,这似乎是一个简单的问题,但我不知道是什么让我的控制台快速打开和关闭?我在main()函数中包含了系统(“暂停”) 节目信息: 该程序用于电影院票务系统,显示哪一排的座位可用(如多维数组所示) 有人知道为什么控制台不能打开吗?我在编译器中没有收到任何错误消息 #include <iostream> #include <fstream> using namespace std; using std::ifstream; void Init(); void Display()

cout因为在ReadPrices()函数中,无法打开prices.dat文件,只需退出(1)应用程序
indata.open("prices.dat");
if(!indata)
{
cerr << "Error: file could not be opened" << endl;
exit(1);
}
indata.open(“prices.dat”);
如果(!indata)
{
cerr我相信exit()是由ReadPrices调用的。
exit()不调用系统(“暂停”)
可能的解决办法:
- std::at_exit()
- 如果ReadPrices函数成功,则使其返回布尔值to标志,而不是调用exit
尝试从命令行运行您的程序。您的程序是如何运行的?我怀疑这与您的程序本身一样是编程环境的问题。@Code Guru-VC++2010
