How can I print name of files with the same month of creation?

[CharAmel]

Hi everyone!

I am making a program in C where the user will input a month then the program prints out all the names of files created in that month. Right now I'm having trouble in printing the names of files. Here's a portion of my code. Can you help me figure out what's wrong with it?

int main (void)
{
    int month;
    scanf("%d", month);  



    DIR *da; 

    struct dirent *ep;  

    time_t temp;
    struct tm *foo = localtime(&temp); 
    struct stat attrib;  

  da = opendir ("./"); 
if (da != NULL) 
{
 while (ep = readdir (da)) 
   while ((ep = readdir (da)) != NULL)
   {
    const size_t len = strlen(ep->d_name);   

    if (len > 4                    &&
        ep->d_name[len - 4] == '.' &&
        ep->d_name[len - 3] == 't' &&
        ep->d_name[len - 2] == 'x' &&
        ep->d_name[len - 1] == 't') {

            stat(ep->d_name, &attrib); 
            foo = localtime(&(attrib.st_mtime));
            month = foo->tm_mon + 1;

            if(month == 1) {
                printf ("%s\n", ep->d_name);
            }

            else if(month == 2) {
                printf ("%s\n", ep->d_name);
            }

What problem are you having? Does it not compile? ...not run? ...run but not produce the result you expect?

[CharAmel]

It runs but it doesn't print out the files created on the month that I inputted.

I edited my code. Please take a look at it.

    DIR *da; 
    struct dirent *ep;  
    struct stat attrib;  

    da = opendir ("./"); 
    if (da != NULL)  
    {
        while (ep = readdir (da)) 
        {
        while ((ep = readdir (da)) != NULL) 
        {
            const size_t len = strlen(ep->d_name);    

                if (len > 4                    && 
                ep->d_name[len - 4] == '.' &&
                ep->d_name[len - 3] == 'T' &&
                ep->d_name[len - 2] == 'X' &&
                ep->d_name[len - 1] == 'T') {

                    stat(ep->d_name, &attrib); 

                    strftime(month, MAX_SIZE, "%m", localtime(&(attrib.st_ctime)));

                    comp = strcmp(month,input);
                    if(comp == 0) {
                        printf ("%s\n", ep->d_name);
                    }   
                } 
           } 
        closedir (da);
        }    
    }

Please post the entire program, not fragments. If it seems too long for pasting into a code block, make it an attachment.
