Pascal is one of the most widely used programming languages due to its simplicity and great functionality. Through Pascal, you can work with files by creating or modifying them using the appropriate functions.

Instructions

Step 1

To create a text file in Pascal, it is necessary to set variables of the appropriate type, which will be written to the corresponding memory section. To do this, you can use the various functions of the language. All data and variables are written using the standard Writeln operation (just specify an additional parameter). Program CreateFile;

var textfile: Text; nametype: String; textstring: String; a, b: integer; Where textfile is a variable of type Text containing the name of the file. Nametype - the type of text input to which the String is assigned. Textstring is a text string of the appropriate type. A and b are auxiliary variables that store integer numeric values.

Step 2

Prompt the user to enter the desired file type nametype. It needs to be linked to the textfile. Writeln itself ('Please, type the name of data typing');

Readln (nametype);

Assign (textfile, nametype);

Step 3

Open the file to write data and prompt the user to enter first the number of lines to write, and then their content. The data will be entered into the document itself one by one. Rewrite (textfile);

Writeln ('Type numbers of strings:');

Readln (b); {variable that stores the number of lines}

Writeln ('Please, type the strings:');

Step 4

To write a fixed number of lines, use a loop, the first parameter of which must correspond to the number of the first line of the file, in this case the number 1. for a: = 1 to b do

begin

Readln (textstring);

Writeln (textfile, textstring); {file write function}

end;

Step 5

Exit the file and end the program using the appropriate functions. Also display a notification about the successful recording. To avoid problems with the output, set a second readln.close (textfile);

Writeln ('Success');

readln;

End.

Step 6

The file was created successfully. Compile and save the script through the menu of your programming environment.
