Calculate Sum of Odd elements in Array using For loop in R

R Programming: Control Structure Exercise-14 with Solution

Write a R program to find the sum of all elements in an array using a for loop.

Sample Solution :

R Programming Code :

# Define a function to find the sum of all odd elements in an array using a for loop
sum_of_odd_elements <- function(arr) {
    # Initialize a variable to store the sum
    sum <- 0
    
    # Iterate through each element in the array
    for (element in arr) {
        # Check if the element is odd
        if (element %% 2 != 0) {
            # Add the odd element to the sum
            sum <- sum + element
        }
    }
    
    # Return the sum of odd elements
    return(sum)
}

# Test the function with an example array
array <- c(10, 20, 30, 41, 50, 60, 73, 80, 90, 101)
result <- sum_of_odd_elements(array)

# Print the result
cat("Sum of all odd elements in the array is:", result, "\n")

Output:

Sum of all odd elements in the array is: 215           

Explatnaion:

In the exercise above,

• The "sum_of_odd_elements()" function takes an array 'arr' as input.
• It initializes a variable 'sum' to store the sum of odd elements and sets it to 0.
• Using a for loop, it iterates through each element in the array.
• For each element, it checks if the element is odd by using the modulus operator (%%). If the remainder is not zero, it means the element is odd.
• If the element is odd, it adds it to the 'sum'.
• After iterating through all elements, it returns the 'sum' of odd elements.
