How to check if string matches pattern C

int main()
    char str[MAXSTR] = "A1234567890";

int isFormat(char str[MAXSTR])
    int len = strlen(str);
    int x=0, result=0;

    if(str[x] >= 'A' && str[x] <=
        for (x=1; x<len; x++)
            if(str[x] >= '0' && str[x]
<= '9')
                result = 1;
                return 0;
    return result;

You can write your own function to check that. This is just one of the example. You can use the isalpha() function, but you may need to include <ctype.h>. isalpha() takes in a char.

You can use Regex, grouping your patterns: using System; using System.Text.RegularExpressions; class Program { static void Main() { // First we see the input string. string input = "/content/alternate-1.aspx"; // Here we call Regex.Match. Match match = Regex.Match(input, @"content/([A-Za-z0-9-]+).aspx$", RegexOptions.IgnoreCase); // H

How to check if regex matches only number?
If I understand the question correctly, you want to check - given some regular expression r - if r might match anything which is not a number. In that sense, the empty regex $^ (matching nothing) would pass the test, since it matches nothing (and hence no non-number). 1[0-9][0-9a-z], however, matches 10s, which is not a number, hence the test fails. That is not possible with Python's regex facili

How can I capture multiple matches for a sub-expression from a single string with Perl?
You are expecting too much from your regular expression. The simplest way is to do this in two steps. Note first of all though that the (.+) which matches show in your example is too general. If you apply the pattern to show _3x01_3x02 ep. name then you will get show -- with a trailing space -- because the following [-._ ]+ (there is no need to escape the dot or enclose the character class in (?:

regular expression in java to check that a string is part of another string (NO SUBSTRING)
Not a direct regex, but given the search string it is easy enough to build one: String main = "complete"; String search = "come"; char[] split = search.toCharArray(); StringBuilder regex = new StringBuilder(".*"); for (int i =0; i < split.length; i++) { regex.append(split[i]).append(".*"); } System.out.println(main.matches(regex.toString())); In this ex
