You can find in-depth information on how to use sscanf() in C file handling on crasseux.com/books/ctutorial/sscanf.html
One more useful website of learning basic of "C Programming" is cprogramming-bd.com
sscanf () function is a function that can be found in
sscanf ([string], "[format specifiers]", ...[Variables where the values will be distributed]);
Example:
char strNew [99] = "Hello World 64";
char strHello [99];
char strWorld [99];
int num;
sscanf (strNew, " %s %s %d", strHello, strWorld, num);
With the example above, after the execution of the program, strHello's value would be "Hello"; strWorld's value would be "World" and num's value is 64.
If you only want a specific value in a string and you want to remove the other values, you can use asterisk (*) after the percent sign to stop scanning that value. In the example above, for example, I only need the number 64. Therefore:
sscanf (strNew, "%*s %*s %d", &num);
SSCANF is the Go Programming Language and originated from the C Programming Language. SSCANF is a function that reads data with specified format from a given stream source.
scanf is a function (available in C and C++)cin is an istream object (C++ only)Advice: when in doubt, use fgets+sscanf
Don't store pointers in files, it makes no sense.
in C: atof, strtod, sscanf
File is a place where information or data is stored. we make use of some of the file-handling functions in c like: fopen()-for opening a file. fclose()-to close a file. Every file being opened for any operations like: "r"- Read-Only mode. "w"-Write-only mode. "a"-append mode. "r+"-read+write mode. "w+"-write+read mode. "a+"-read+append mode. We should make use of FILE pointer ,in order to perform any such operations on the files. There are many input and output functions used along with files. fgetc() fgets() fscanf() fputc() fprintf() fputs() fseek() rewind() File handling is used to read or write a file without directly opening it.its contents are opened in another files by using above specified commands in c++ programming for file handling we have to use a header file but in c noheader file regarding to file handling is required
Use functions like fopen, fclose, fgets, sscanf, strtok

yes
sscanf, atoi, strtol, ...

open, read/write, close
With functions like sscanf, strtol, strtoul, atoi, atof etc.
File handling is simply the process of opening, reading, writing and closing files. Files are simply streams for input and output, or the "serialisation" of objects. In other words, reading and writing data to and from disk storage.
yes sir
