R Programming: Generate first 10 Fibonacci numbers

R Programming: Basic Exercise-5 with Solution

Write a R program to get the first 10 Fibonacci numbers.

Sample Solution :

R Programming Code :

# Initialize a numeric vector 'Fibonacci' of length 10 with zeros
Fibonacci <- numeric(10)

# Set the first two elements of the 'Fibonacci' vector to 1
Fibonacci[1] <- Fibonacci[2] <- 1

# Loop through indices 3 to 10 to calculate Fibonacci numbers
# Each element is the sum of the two preceding elements
for (i in 3:10) Fibonacci[i] <- Fibonacci[i - 2] + Fibonacci[i - 1]

# Print a message indicating that the first 10 Fibonacci numbers will be shown
print("First 10 Fibonacci numbers:")

# Print the 'Fibonacci' vector to display the first 10 Fibonacci numbers
print(Fibonacci)

Output:

[1] "First 10 Fibonacci numbers:"
 [1]  1  1  2  3  5  8 13 21 34 55                         

Explanation:

• Initialize Fibonacci Vector:
• Fibonacci <- numeric(10): Creates a numeric vector Fibonacci of length 10, initialized with zeros.
• Set Initial Values:
• Fibonacci[1] <- Fibonacci[2] <- 1: Sets the first two elements of the vector to 1. These represent the first two numbers in the Fibonacci sequence.
• Compute Fibonacci Sequence:
• for (i in 3:10) Fibonacci[i] <- Fibonacci[i - 2] + Fibonacci[i - 1]: Loops from the third to the tenth element. Each element is computed as the sum of the two preceding elements.
• Print Results:
• print("First 10 Fibonacci numbers:"): Prints a message indicating that the following output is the Fibonacci sequence.
• print(Fibonacci): Displays the vector containing the first 10 Fibonacci numbers.
