如何在 KDevelop 中查看变量的值?

[英]How to view values of variables in KDevelop?

I am using KDevelop as IDE for my C++ program.我使用KDevelop作为我的C++程序的 IDE。 I have an array char buffer[1024] in my program.我的程序中有一个数组char buffer[1024] After reading data to buffer, I would like to check it manually.将数据读取到缓冲区后,我想手动检查它。 But in the left panel, I need to read the array character by character .但是在左侧面板中,我需要character by character读取数组。 Is there some way by which I can get the content of the array at a stretch?有什么方法可以一次性获取数组的内容吗?

Use GDB tool view available in KDevelop. 使用KDevelop中可用的GDB工具视图。 In KDevelop 4.6, Window->Add ToolView->GDB will open the GDB tool view at the bottom/left/right of KDevelop IDE . 在KDevelop 4.6中, Window->Add ToolView->GDB将在KDevelop IDE的底部/左侧/右侧打开GDB工具视图。 Debug your program and at the point at which you have to check value of the variable, enter print variable_name in the textbox corresponding to GDB cmd . 调试程序,然后在必须检查变量值的位置,在与GDB cmd对应的文本框中输入print variable_name The value of variable will be printed. 变量的值将被打印。

Some example commands: 一些示例命令:

Show an array (will show first 200 elements by default): 显示一个数组(默认情况下将显示前200个元素):

(gdb) print buffer
print buffer
$1 = "\000\001\002\003\004\005\006\a\b\t\n\v\f\r\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037 !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~\177\200\201\202\203\204\205\206\207\210\211\212\213\214\215\216\217\220\221\222\223\224\225\226\227\230\231\232\233\234\235\236\237\240\241\242\243\244\245\246\247\250\251\252\253\254\255\256\257\260\261\262\263\264\265\266\267\270\271\272\273\274\275\276\277\300\301\302\303\304\305\306\307"...
