strtok #include <cstring> char *strtok( char *str1, const char *str2 ); The strtok() function returns a pointer to the next "token" in str1, where str2 contains the delimiters that determine the token. strtok() returns NULL if no token is found. In order to convert a string to tokens, the first call to strtok() should have str1 point to the string to be tokenized. All calls after this should have str1 be NULL. For example: char str[] = "now # is the time for all # good men to come to the # aid of their country"; char delims[] = "#"; char *result = NULL; result = strtok( str, delims ); while( result != NULL ) { printf( "result is \"%s\"\n", result ); result = strtok( NULL, delims ); } The above code will display the following output: result is "now " result is " is the time for all " result is " good men to come to the " result is " aid of their country" Related topics strchr - strcspn - strpbrk - strrchr - strspn - strstr
