Question

Составьте программу позволяющую удвоить каждый символ заданной строки и вывести полученную строку на экран

Answer 1

Var a,b:string;
i: integer;
begin
write('Введите строку: '); readln(a);
b:='';
for i:= 1 to length(a) do b:=b+a[i]+a[i];
write('Новая строка: ',b);
end.

Program to Double Each Character in a String

Here's a program in Python that allows you to double each character in a given string and then prints the resulting string:

def double_characters(string):
    doubled_string = ''
    for char in string:
        doubled_string += char * 2
    return doubled_string

input_string = input("Enter a string: ")
result = double_characters(input_string)
print("Doubled string:", result)

Explanation: 1. The `double_characters` function takes a string as input. 2. It initializes an empty string `doubled_string` to store the doubled characters. 3. It iterates over each character in the input string using a `for` loop. 4. For each character, it appends the character twice to the `doubled_string`. 5. Finally, it returns the `doubled_string`. 6. The program prompts the user to enter a string using the `input` function. 7. It calls the `double_characters` function with the input string as an argument and stores the result in the `result` variable. 8. It prints the doubled string by using the `print` function.

Example: Suppose you enter the string "Hello" as input. The program will double each character in the string and print the result as "HHeelllloo".

Please note that this program is written in Python. If you want to implement it in a different programming language, the syntax and approach may vary.
