Get a string from a stream: how to use fgets #include <stdio.h> int main() { FILE *file; char string [100]; file = fopen ("my.txt" , "r"); if (file == NULL) perror ("Error reading file"); else { fgets (string , 100 , file); puts (string); fclose (file); } return...
In this modified example, we use awhile(1)loop and explicitly check forEOFafter attempting to read a character. IfEOFis encountered, we usefeofto confirm that it is indeed the end of the file. feofis often used in conjunction with other file stream functions likefread,fgets, andfscanfto ...
I would advise to never usesizeof(even if it can be used) to get any of the two different sizes of an array, either in number of elements or in bytes, which are the last two cases I show here. For each of the two sizes, the macros shown below can be used to make it safer. ...
You can also use fgets for the same purpose. This reads input till a newline is read or until the specified size is reached, with the size specified as arguments: char str[50]; fgets(str, 50, stdin); 31st Jul 2019, 2:07 AM Kinshuk VasishtResponder...
You can use VPN to implement network security policy. For example, if yourun your own email server, you can require users to log in only from the IP address of the VPN server bycreating an IP address whitelist in the firewall. Thus, your email server is hardened to prevent hacking activ...

As Peter87 said,gets()has been removed from the latest standards. If you don't want to usefgets()there isgets_s(). https://en.cppreference.com/w/c/io/gets Apr 29, 2019 at 10:01pm salem c(3698) Also here ->https://sekolahkoding.com/forum/gets-identifier-is-undefined-1556381460 ...

As you can see, I have defined macros with the same names for different operating systems. Surprisingly, this is the crux of the cross-platform programming: we encapsulate platform specifics in objects with same names and later we use them as usual functions. For instance, to close a socket...
For example in above , I want to parse all the messages into excel , tried to use Power-Query but not sure what to do as next step.. or by any other methods also if this is possible( Except VBA/Coding) Many Thanks Br, Anupam ...
