C Modifying A Record In Binary File Stack Overflow

C Modifying A Record In Binary File Stack Overflow Everything works well until the modify part (modifieretudiant method). i'm reading the name from the user so i can later check if it does exist in the binary file. Discover how to effectively modify a record in a binary file using c programming. this guide will help you understand the necessary steps to read, edit, and.

C Binary File Read Error Stack Overflow I am working on a program that manages records and specifically on a function to update individual members of a record (struct). i looked up the fseek () function, but don't understand how to determine which exact bytes i need to update overwrite. Why are you checking stdin for eof in a function to modify a binary file? also i believe fseek (f, sizeof (s), seek cur) would make it more readable than using 0,1,2. So this is my code to "modify a record from a binary file", and it should work fstream file; student st, temp; student is a class which i made. int rollno; clrscr(); cout << "enter the roll number: "; cin >> rollno; to get the roll number which is to be modified. Opening (or creating) a text file with update mode may instead open (or create) a binary stream in some implementations. (emphasis added.) fgetc() returns an int quotes from iso iec 9899:2011, the current c standard. §7.21 input output §7.21.1 introduction.

I have written a basic binary file handling program and have used goto, so i want to know how to improve this program by replacing goto with another function #include #include
