1. Leap Year Detectorby CodeChum Admin
Let’s try to find out whether a year has 365 or 366 days. To do this, we need to create a leap year detector!
Conditions for a leap year:
1.) year must be divisible by 4 and not divisible by 100
2.) If year is divisible by 100, it must be divisible by 400 for it to be a leap year.
Instructions:
You are provided with the isLeapYear() function which is already declared and defined for you.Your task is to ask the user for a year and then call the isLeapYear function to check whether the year is a leap year or not.Input
1. Year to be checked
Output
If a certain year is a leap year, print "<INSERT_YEAR_HERE> is a leap year"Otherwise, print "<INSERT_YEAR_HERE> is not a leap year"
Enter year: 20202020 is a leap year
Problem Definition
The Gaussian distribution is given by:
Where μ, is the mean, sd, is the standard deviation, and t, is the variable of the function; e is the exponential function
and = 3.1415 (Note: pi constant)
f(t)=¹_e-² (²-4)³²
o√2π
Write a C++ program that asks the user to enter the values of μ, s, and t; then calculates and prints the value of f(t).
Use the C++ function 'exp' to compute the exponential of .x (e). Your program should:
a) Use appropriate variable names, and meaningful comments to describe the algorithm.
b) Use appropriate messages and a suitable format to display the result (see Figure 1)
c) Display the floating-point numbers up to 3 decimal places.
GAN C:\WINDOWS\system32\cmd.exe
Enter mean: 1.4
Enter standard deviation (sd)
Enter time: 0.95
f(t) -0.030
