典型的指针使用错误,你定义了一个指针变量,只能用来保存地址,如果这个地址所指向的空间不是系统分配给它的,那么你对这块内存的赋值是非法的,就好比你的“所作所为”:char *b;//下面的三重循环,你非法修改了至少 3*3*5 = 45 字节的内存值,要知道以前 windows 98 的蓝屏大部份是由于非法修...

Could you help me resolve this warning ? Collaborator It is because hasBytesAvaliable hasn't been set, so initialising it to 0 would fix this warning. Strangely I cant get this warning to appear on iOS or OS X. What version of Xcode are you using?
Function Naming Since NPP is a C API and therefore does not allow for function overloading for different data-types the NPP naming convention addresses the need to differentiate between different flavors of the same algorithm or primitive function but for various data types. This disambiguation...

To understand “segmentation fault (aka segfault),” it is a must to know the basic idea of segmentation and its implementation in C programming. This blog will also cover a scenario that causes “segmentation fault.” Understanding memory management methods To understand segmentation fault, it is...
