1. Problem Description
The problem consists of several independent questions related to programming concepts and mathematical expressions. We need to solve each question individually and provide the correct answer.
2. Solution Steps
Question 6: Pseudo code output
* a = 5, c = 2
* Repeat:
* c = c + 1
* a = a + c
* Until (c > 3)
* Print a
Iteration 1:
c = 2 + 1 = 3
a = 5 + 3 = 8
c > 3 is false.
Iteration 2:
c = 3 + 1 = 4
a = 8 + 4 = 12
c > 3 is true. The loop terminates.
Output: a = 12
Question 7: Expression evaluation 8 - 2 * 5 MOD 3 + 5
* Multiplication: 2 * 5 = 10
* Expression: 8 - 10 MOD 3 + 5
* Modulo: 10 MOD 3 = 1
* Expression: 8 - 1 + 5
* Subtraction: 8 - 1 = 7
* Expression: 7 + 5
* Addition: 7 + 5 = 12
Question 8: Pascal expression 8 + 5 mod 4 * 4 - 2 DIV 2
* 5 mod 4 = 1
* 2 DIV 2 = 1
* Expression: 8 + 1 * 4 - 1
* Multiplication: 1 * 4 = 4
* Expression: 8 + 4 - 1
* Addition: 8 + 4 = 12
* Expression: 12 - 1
* Subtraction: 12 - 1 = 11
Question 9: 17 mod 2
* 17 mod 2 = 1
Question 10: Logical expressions evaluation
* Expression 1: 2^3 + 2 > 4 * 3
* 2^3 = 8
* Expression: 8 + 2 > 12
* 10 > 12, which is False.
* Expression 2: 6/2 + 5 < 5 * 3 - 2
* 6/2 = 3
* Expression: 3 + 5 < 15 - 2
* 8 < 13, which is True.
Result: False, true
Question 11: Expression 1 + 5 * (4 * 3 - 10)
* Parenthesis: 4 * 3 = 12
* Expression: 1 + 5 * (12 - 10)
* Parenthesis: 12 - 10 = 2
* Expression: 1 + 5 * 2
* Multiplication: 5 * 2 = 10
* Expression: 1 + 10
* Addition: 1 + 10 = 11
Question 12: Pascal expressions
* Expression A: writeln(4 + 15 div 4 - 16 mod 3);
* 15 div 4 = 3
* 16 mod 3 = 1
* Expression: 4 + 3 - 1
* Addition: 4 + 3 = 7
* Expression: 7 - 1
* Subtraction: 7 - 1 = 6
* Expression B: writeln(3 * 15/9);
* 3 * 15 = 45
* Expression: 45/9
* 45/9 = 5.0 (or 1.6 if it does integer division first)
Note: Pascal performs real division (/)
3*15/9 = 45/9 = 5
So, the answer is 6 and
5.
Question 13: 5 MOD 3 and 3 MOD 5
* 5 MOD 3 = 2
* 3 MOD 5 = 3
3. Final Answer
