Reading and writing to a text file For reading and writing to a text file, we use the functions fprintf and fscanf. They are just the file versions of printf and scanf.

The only difference is that, fprint and fscanf expects a pointer to the structure FILE. Writing to a text file Example 1: After you compile and run this program, you can see a text file program.

Other functions like fgetcharfputc etc. Reading and writing to a binary file Functions fread and fwrite are used for reading from and writing to a file on the disk respectively in case of binary files.

Writing to a binary file To write into a binary file, you need to use the function fwrite. The functions takes four arguments: Address of data to be written in disk, Size of data to be written in disk, number of such type of data and pointer to the file where you want to write.

We declare a structure threeNum with three numbers - n1, n2 and n3, and define it in the main function as num. Now, inside the for loop, we store the value into the file using fwrite. The first parameter takes the address of num and the second parameter takes the size of the structure threeNum.

Since, we're only inserting one instance of num, the third parameter is 1.


Finally, we close the file. Reading from a binary file Function fread also take 4 arguments similar to fwrite function as above. You'll get the same records you inserted in Example 3. Getting data using fseek If you have many records inside a file and need to access a record at a specific position, you need to loop through all the records before it to get the record.This site uses cookies for analytics, personalized content and ads.
