Variable Declarations:
Several variables are declared, including sentenceLength, numberWords, numberVowels, i, j, k, Sentence, and sum. These variables will be used to store various information about the sentence being analyzed. Input:
The algorithm reads input from the user, expecting a sentence stored in the variable Sentence. Calculate Sentence Length:
A WHILE loop runs until a period (.) is encountered in the sentence. Inside the loop, the sentenceLength is incremented for each character, and the loop index i is incremented. This loop calculates the length of the sentence. Count Words:
Another WHILE loop runs through each character of the sentence (j < sentenceLength). If a space character is encountered (Sentence[j] = " "), the numberWords counter is incremented. This loop counts the number of words by counting spaces. Count Vowels:
Similar to the previous loop, a WHILE loop iterates through each character of the sentence (k < sentenceLength). If the current character is a vowel (a, e, i, o, or u), the numberVowels counter is incremented. This loop counts the number of vowels in the sentence. Output:
The algorithm uses the Write() function to output the calculated sentenceLength, numberWords, and numberVowels. In summary, the algorithm takes a sentence as input and then calculates its length, the number of words, and the number of vowels. It achieves this by utilizing loops and conditional statements.
