Visual Basic

Visual Basic is Easy to learn Programming language. With Visual Basic you can develop Windows based applications and games. When first released in 1991, it was similar to Microsoft's QuickBASIC, With its visual user interface development tools.

File operation

File operation

There are two distinct ways to perform the file operation in C:

1. Low level I/O operation (it uses UNIX system call
therefore we won't discuss here)

2. High level I/O operation (it uses function in C's Standard I/O library)

List of I/O function with their operation:

fopen() creates a new file for use or opens an existing file for use.
fclose() close a file which has been opened for use.
getc() reads a character to a file.
putc() writes a character to a line.
fprintf() writes a set of data values to a file.
fscanf() reads a set of data values from a file.
getw() reads an integer from a file.
putw() writes an integer to a file.
feof() test for an end of file condition.
