sscanf not parsing string properly

#include <stdio.h>

int main()
{
    char str[] = "[email protected], 22:44:45";
    char user[45], email[45];
    int h, m, s;
    sscanf(str, "%44s@%44s, %d:%d:%d", user, email, &h, &m, &s);
    printf("User: %s | Email: %s | Hour: %d | Minutes: %d | Seconds: %d\n", user, email, h, m, s);
    return 0;
}

Output: User: [email protected], | Email: garbage | Hour: garbage | Minutes: garbage | Seconds: garbage Why is it storing everything up to , into user?

%44s@ doesn't stop reading the string when it gets to the @ character. It means to read a string until whitespace, up to 44 characters. Then it needs to read a @ character after that in order to continue parsing the rest of the string.

To read characters up to @, use %44[^@]. Then follow this with @ to skip over that character before extracting the next string.

    sscanf(str, "%44[^@]@%44[^,], %d:%d:%d", user, email, &h, &m, &s);
