Benchmark: C-strings (null-terminated char array) vs ptr+length vs ptr+ptr_end - gh0st-work/c-str-bench
这种以Null结尾的字符串通常被称为C风格字符串或者以Null结尾的字符串(Null-terminated string)。它是C语言中常用的字符串表示方式,也被许多其他编程语言所支持和采用。 优势: 内存动态分配:使用calloc可以根据需要动态分配字符串所需的内存空间,避免了静态分配固定大小的字符串可能带来的内存浪费或不足的问题。

For example, the following type declarations could be used to store null-terminated strings. type TIdentifier =array[0..15]ofChar; TFileName =array[0..259]ofChar; TMemoText =array[0..1023]ofWideChar; With extended syntax enabled ({$X+}), you can assign a string constant to a statica...
The following test case causes ASAN to report stack-buffer-overflow. It seems that the array is viewed as NULL terminated string and the library tries to read 4 bytes from it instead of 3. DOCTEST_TEST_CASE("simple_test") {chararr[] = {'a','b','c'}; ...

One common mistake is forgetting to include the Null Character in C at the end of a string or character array. This omission can lead to undefined behavior or unexpected results when working with C strings. It is crucial to ensure that strings are properly terminated with the Null Character ...

null终止符(Null-terminated)是一种在计算机编程中常用的字符串表示方法,它使用一个特殊的字符(通常是ASCII码为0的字符)作为字符串的结束标志。在二进制文件解析中,null终止符并不适合解析二进制文件。 二进制文件是由一系列字节组成的,其中包含了各种数据类型的信息,如整数、浮点数、字符等。与文本文件不同,二进制...
