This document contains code snippets in different programming languages like C#, C++, and pseudocode demonstrating basic programming concepts like variables, input/output, conditional statements, and switch/case statements. The code examples include: 1. C# code to calculate the perimeter of a rectangle by getting user input for the length and multiplying it by itself. 2. C++ code to calculate the 4th power of a number entered by the user. 3. Pseudocode demonstrating a simple if-then conditional statement to check if a student's average is 10 to determine if they get a diploma. 4. Pseudocode showing a switch/case statement to perform different mathematical operations like addition

4. CONDITIONAL

5. Simple Conditional(Ifthen) Condition T Action 1 F

6. If the student had 10 average, then, obtain diploma. Simple conditional Start Average Average= 10 T Diploma F End

7. CASE (SELECTOR MÚLTIPLE) 1 4 Selector 2 3 Action 1 : Action N Action 1 : Action N Action 1 : Action N Action 1 : Action N

8. CASE (SELECTOR MÚLTIPLE) 1 4 Selector 2 3 T= a + b T= a / b T= a - b T= a * b T

9. Start Type two values START SHOW “Type a mathematical operator to selection: + for addition, / for divisions, - for subtraction and * for multiplication.” READ Selector CASE 1 DO T= a + b CASE 2 DO T= a / b CASE 3 DO T= a - b CASE 4 DO T= a * b END CASE SHOW T END a, b + * Selector Type a mathematical operator to select: + for addition, / for division, - for subtraction, * for multiplication - / T= a + b T= a / b T= a - b T= a * b T End

10. Enter a value: Enter b value: Enter a symbol to select a operation + for addition / division - subtraction * multiplication Total
