C++for循环跳过cin.get()

C++ for loop skips cin.get()

本文关键字:get cin 循环 C++for      更新时间:2023-10-16

在这个for循环中,cin.get();每隔一次跳过一次。我不知道为什么要跳过它。如有任何帮助,我们将不胜感激。

代码:

for(Pointer = StartPointer; Pointer < EndPointer; Pointer += MemInfo.RegionSize)
{
    VirtualQueryEx(hProc, (LPCVOID)(Pointer), &MemInfo, sizeof(MemInfo));
    cout << "MemInfo AllocationBase: " << MemInfo.AllocationBase << endl;
    cout << "MemInfo AllocationProtect: " << MemInfo.AllocationProtect << endl;
    cout << "MemInfo BaseAddress: " << MemInfo.BaseAddress << endl;
    cout << "MemInfo Protect: " << MemInfo.Protect << endl;
    cout << "MemInfo RegoinSize: " << MemInfo.RegionSize << endl;
    cout << "MemInfo State: " << MemInfo.State << endl;
    cout << "MemInfo Type: " << MemInfo.Type << endl;
    cout << "MemInfo Size: " << sizeof(MemInfo) << endl;
    cout << "Starter pointer is: " << StartPointer << endl;
    cin.get();
}

cin.get()之间的输出示例;

MemInfo AllocationBase: 00000000
MemInfo AllocationProtect: 0
MemInfo BaseAddress: 00000000
MemInfo Protect: 1
MemInfo RegoinSize: 65536
MemInfo State: 65536
MemInfo Type: 0
MemInfo Size: 28
Starter pointer is: 0
MemInfo AllocationBase: 00010000
MemInfo AllocationProtect: 4
MemInfo BaseAddress: 00010000
MemInfo Protect: 4
MemInfo RegoinSize: 65536
MemInfo State: 4096
MemInfo Type: 262144
MemInfo Size: 28
Starter pointer is: 0

cin.get()没有得到您键入的'n' ~

尝试使用,

string str;
getline(cin, str) 

而不是cin.get()

或在cin.get() 之后添加getchar()

由于您使用的是Windows:

#include <conio.h>
// .. your other stuff
_getch();

cin.get()会抓取输入缓冲区中的任何内容(如果你按下回车键、空格键或在键盘上呼吸,它就会有东西),或者EOF,如果什么都没有,它总是会返回。
