C program could not be executed at Windows command prompt

[Dhamnekar Win,odd]

 I have downloaded and installed ' C c-programs application from Windows store. I copied one program named 'Days Convertion' from it to my Notepad++  and saved it as c source file in the Documents folder. When I tried to compile it using gcc, gcc said unable to find the file. How can I fix this error?

The c program is as follows:

/*    Write a c program to convert given number of days to a measure of time


  *    given in years, weeks and days. For example 375 days is equal to 1 year


  *    1 week and 3 days (ignore leap year)


  */




 #include stdio.h


 #define DAYSINWEEK 7




 void main()


 {


    int ndays, year, week, days;




    printf("Enter the number of days\n");


    scanf("%d",&ndays);




    year = ndays/365;


    week = (ndays % 365)/DAYSINWEEK;


    days = (ndays%365) % DAYSINWEEK;




    printf ("%d is equivalent to %d years, %d weeks and %d days\n",


           ndays, year, week, days);


 }




 /*-----------------------------------------------

When I tried to compile it using gcc at windows command prompt, I got the following error several times. After giving this command at command prompt, 'DaysConvertion.c' file disappeared from the Documents folder. 

How can I fix this error?

This program is incorrect. It does not take into account leap years..

Yes. From that point of view, this program is wrong. But we already decided to ignore the leap year and we mentioned that as  the comment.
