Pyramid Schemes
by CodeChum Admin
They said pyramids were created by aliens, so if you can make a pyramid you might be able to qualify as an alien.
Instructions:
- In the code editor, you are provided with a main() function that asks the user for an integer input n, and passes this value to the function call of the generatePattern() function.
- Your task is to implement this generatePattern() function which has the following description:
- Return type - void
- Function name - generatePattern
- Parameters - 1 integer n
- Description - this function prints a triangular pattern of letter T's based on the value of n. For more information, refer to the output in the test cases
- DO NOT EDIT ANYTHING IN THE MAIN
Input
1. Integer n
Output
Enter·n:·4
T
TT
TTT
TTTTComparing Characters
by CodeChum Admin
Most, if not all things have numeric values. That goes for characters too. In order to find out which character has a higher value, we have to compare them with each other and display the value of the higher character.
Instructions:
- In the code editor, you are provided with a main() function that asks the user for 2 characters, passes these characters to a function call of the getHigherValue() function, and then prints out the ASCII value of the higher character.
- Your task is to implement the getHigherValue function which has the following details:
- Return type - int
- Name - getHigherValue
- Parameters - 2 characters to be compared
- Description - the ASCII value of the higher character.
- Hint: Comparing characters in C++ is just like comparing integers.
- DO NOT EDIT ANYTHING IN THE MAIN
Input
1. First character
2. Second character
Output
Enter·first·character:·a
Enter·second·character:·h
Result·value·=·104What is the wavelength of EM radiation that ejects 2.00 -eV electrons from calcium metal, given that the binding energy is 2.71 eV? What type of EM radiation is this?
