2023年6月7日 · C provides two functions strtok() and strtok_r() for splitting a string by some delimiter. Splitting a string is a very common task. For example, we have a comma-separated list of items from a file and we want individual items in an array.

2016年7月15日 · strtok() modifies its argument string by terminating tokens with NUL before returning. If you try to examine the whole buffer (str []) you'll see it being modified between successive calls to strtok(). Instead of watching str, watch str[0], str[1], str[2], ... @pmg:I watched str [0] and str [1].str [1] should be '\0',but it was a space there.

The strtok() function splits a string into multiple pieces (referred to as "tokens") using delimiters. The first call to strtok() should have a pointer to the string which should be split, while any following calls should use NULL as an argument.

The C Library strtok() function is used for tokenizing strings. These strings are a set of tokens using delimiters/separators characters. In general, tokens are usually words, phrases, or individual characters within a string. Here, char *strtok(char *str, const char *delim) breaks string str into a series of tokens using the delimiter delim ...

2023年10月18日 · The strtok() function splits the string into substrings by separating the original string using delimiters. It is defined inside the <string.h> header so we need to include it before using the strtok() function.

Once the terminating null character of str is found in a call to strtok, all subsequent calls to this function (with a null pointer as the first argument) return a null pointer.

2024年6月28日 · To split a string by multiple delimiters in C, we can use the strtok () function from the standard library.

2022年8月23日 · The strtok() function splits the string parameter into tokens based on one or more delimiters, and returns the pointer to the first token. Subsequent calls to strtok() , with string set to NULL , return a pointer to the next tokenized string.

2022年12月23日 · C strtok() function - Split string into tokens. Syntax: char *strtok(char *strToken, const char *strDelimit) The strtok() function is used to read string1 as a series of zero or more tokens, and string2 as the set of characters serving as delimiters of the tokens in string1.

2025年2月18日 · The strtok_s function differs from the POSIX strtok_r function by guarding against storing outside of the string being tokenized, and by checking runtime constraints. The Microsoft CRT strtok_s signature matches this POSIX strtok_r definition, not the C11 strtok_s .
