The C library function char *strtok(char *str, const char *delim) breaks string str into a series of tokens using the delimiter delim.
Following is the declaration for strtok() function.
char *strtok(char *str, const char *delim)
str − The contents of this string are modified and broken into smaller strings (tokens).
delim − This is the C string containing the delimiters. These may vary from one call to another.
This function returns a pointer to the first token found in the string. A null pointer is returned if there are no tokens left to retrieve.
The following example shows the usage of strtok() function.
#include <string.h> #include <stdio.h> int main () { char str[80] = "This is - www.tutorialspoint.com - website"; const char s[2] = "-"; char *token; /* get the first token */ token = strtok(str, s); /* walk through other tokens */ while( token != NULL ) { printf( " %s\n", token ); token = strtok(NULL, s); } return(0); }
Let us compile and run the above program that will produce the following result −
