Truncate Specific Parts of a String
How do you truncate specific parts of a string.
Example:
1 This is the string
Goal:
This is the string
As you can see I'm trying to simply remove the first two characters of the string the number one and the space between the one and the word "this."
Your help is appreciated.

ustrtok
ustrtok(3alleg4) Allegro manual ustrtok(3alleg4)
NAME
ustrtok - Retrieves tokens from a string. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *ustrtok(char *s, const char *set);
DESCRIPTION
This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be
searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always
copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the
same time). Example:
char *word;
char string[]="some-words with dashes";
char *temp = ustrdup(string);
word = ustrtok(temp, " -");
while (word) {
allegro_message("Found `%s'
", word);
word = ustrtok(NULL, " -");
}
free(temp);
RETURN VALUE
Returns a pointer to the token, or NULL if no more are found.
