Write the pseudocode & flowchart that receives a letter from a user and displays the corresponding color
Certainly! Here's an example of pseudocode and a corresponding flowchart that receives a letter from a user and displays the corresponding color:
Pseudocode:
```
1. Prompt the user to enter a letter.
2. Read the letter input from the user.
3. Convert the letter to uppercase to ensure case-insensitive matching.
4. Compare the letter with the set of predetermined letters and assign the corresponding color.
5. If the letter matches, display the corresponding color.
6. If the letter does not match, display an error message indicating an invalid input.
7. End the program.
```
Flowchart:
```
start --> input prompt --> read input (letter) --> convert letter to uppercase --> decision (letter matches?)
--> | yes | --> display corresponding color --> end
--> | no | --> display error message --> end
```
The flowchart represents the steps outlined in the pseudocode. It begins with an input prompt, followed by reading the input letter and converting it to uppercase. Then, it checks if the letter matches any of the predetermined ones. If a match is found, it proceeds to display the corresponding color. If there is no match, an error message is displayed. Finally, the program ends.
