Question

Составьте программу, входящую true,если высказывание является истинным,и false в противном случае: а)сумма цифр трехзначного числа х является четным числом; б) треугольник со сторонами a,b,c является разносторонним

Answer 1

1 :

 

Program P1;
Uses Crt;
Var x : Integer;

Begin
ClrScr;
Write('Введи x: ');
Readln(x);

Write((x mod 10 + x div 10 mod 10 + x div 100) mod 2 = 0);

Readln;
End.

 

2:

 

Program P2;
Uses Crt;
Var a, b, c : Integer;

Begin
ClrScr;
Write('Введи a, b, c: ');
Readln(a, b, c);

Write((a <> b) and (b <> c) and (a <> c));

Readln;
End.

Program to Determine Truth Value of Statements

To create a program that evaluates the truth value of given statements, we can use the following logic:

# a) Check if the sum of the digits of a three-digit number is even:

```python def is_sum_of_digits_even(x): # Extracting the digits of the number digit1 = x // 100 digit2 = (x // 10) % 10 digit3 = x % 10 # Calculating the sum of the digits digit_sum = digit1 + digit2 + digit3 # Checking if the sum is even return digit_sum % 2 == 0 ``` Example usage: ```python number = 345 result = is_sum_of_digits_even(number) print(result) # Output: True ```

# b) Check if a triangle with sides a, b, and c is scalene (all sides are different):

```python def is_scalene_triangle(a, b, c): return a != b and a != c and b != c ``` Example usage: ```python side1 = 3 side2 = 4 side3 = 5 result = is_scalene_triangle(side1, side2, side3) print(result) # Output: True ```

These functions can be used to determine the truth value of the given statements.
