number of characters of string in pascal
Pascal: Number of Characters in a String
To determine the number of characters in a string in Pascal, you can use the Length
function. The Length
function returns the number of characters in a string.
Here's an example of how to use the Length
function in Pascal:
program CountCharacters;
var
str: string;
count: integer;
begin
str := 'Hello, World!';
count := Length(str);
writeln('Number of characters: ', count);
end.
In this example, the str
variable is assigned the value "Hello, World!". The Length
function is then used to determine the number of characters in the string, and the result is stored in the count
variable. Finally, the result is displayed using the writeln
function.
The output of this program will be:
Number of characters: 13
So, in Pascal, the Length
function can be used to find the number of characters in a string.
