首先包含了 stdio.h 和string.h 头文件,用于输入输出和字符串操作函数。 memset 函数: memset 函数在 string.h 中定义,它的原型是 void *memset(void *s, int c, size_t n);。 它将s 指向的内存区域的前 n 个字节设置为 c 的值。在上述代码中,我们将 str1 和str2_modifiable 所指向的内存区域的所...
Repeat this step for all elements of the string. 2)The main() calls the deleteduplicate(char *s, char c)by passing the string and the duplicate character as arguments to the function to delete the repeated elements from the string. The function deleteduplicate(char *s,char c) a)k=0, ...

new and delete In previous versions of the library, the implementation-defined operator new and delete functions were exported from the runtime library DLL (for example, msvcr120.dll). These operator functions are now always statically linked into your binaries, even when using the runtime ...
Use this option if you want to prefix the string “error:” to the beginning of error messages so they are more easily distinguishable from warning messages. The prefix is also attached to warnings that are converted to errors by -errwarn. Table B-1 The -errfmt Flags Flag Meaning error...
--path-mappings=<string> - Translates between client paths (as seen by a remote editor) and server paths (where clangd sees files on disk). Comma separated list of '<client_path>=<server_path>' pairs, the first entry matching a given path is used. e.g. /home/project/incl=/opt/incl...
