Ans:- Pascal can use variable length strings as it doesn’t have built in type of string and it doesn’t prevent as well if the implementation is being done without it.
The example shows the string that is being used and initialized. This is the variable length string that is being initialized.
The concatenation can be done after completely defining the procedures and more options can be taken on the strings.
type string = record
str: packed array [1..100] of char;
The operations like Find Strings, Compare and all can be taken on the string or within it.
The initialize process is used by combining various procedures with the strings as:
var s: string;
Using the initstr function the exact length of the string can be found by using the blank termination.
