pascal read
Sure, I'll provide the information you're looking for without any personal sentences.
In Pascal, the read
statement is used to read input from the user. It allows the program to wait for the user to enter a value, and then assigns that value to a variable.
Here's the basic syntax of the read
statement in Pascal:
read(variable);
In this syntax, variable
is the name of the variable that will hold the input value. After the user enters a value, it will be stored in the specified variable.
For example, let's say we want to read an integer value from the user and store it in a variable called num
. We can use the following code:
var
num: Integer;
begin
write('Enter a number: ');
read(num);
end.
In this code, the read
statement is used to read an integer value from the user and assign it to the variable num
. The write
statement is used to prompt the user to enter a number.
That's the basic usage of the read
statement in Pascal. It allows you to read input from the user and store it in variables for further processing in your program.
