SET B QUESTION – 01

  1. Prompt user to input a string and store it in the variable 'string'.
  2. Initialize a variable 'vowels' to 0.
  3. Define a string 'vowel' containing all vowel characters: "aeiouAEIOU".
  4. Iterate through each character 'i' in the input string: a. Check if 'i' is present in the 'vowel' string. b. If yes, increment the 'vowels' count by 1.
  5. Calculate the number of consonants by subtracting the number of vowels from the total length of the string.
  6. Display the count of vowels and consonants using formatted strings.

Pseudocode: Input: string Output: Number of vowels, Number of consonants

string = input("Enter string:") vowels = 0 vowel = "aeiouAEIOU"

for i in string: if i in vowel: vowels = vowels + 1

consonents = length(string) - vowels

print("Number of vowels are:", vowels) print("Number of consonants are:", consonents)

  4. Check if the script is being run as the main program: a. If true, call the main() function.

Pseudocode: Function input_matrix(rows, cols): matrix = [] Display prompt for matrix elements For each row i in range(rows): row = [] For each column j in range(cols): element = Get input for element at position (i+1, j+1) Append float(element) to row Append row to matrix Return matrix

Function matrix_multiply(A, B): rows A, cols A = Get dimensions of A rows B, cols B = Get dimensions of B If cols A != rows B: Return "Error: Matrices cannot be multiplied; since the number of columns in A is not equal to the number of rows in B." result = Create matrix filled with zeros of dimensions (rows A x cols B) For each row i in range(rows A): For each column j in range(cols B): For each element k in range(cols A): result[i][j] += A[i][k] * B[k][j] Return result

Function main(): rows A, cols A = Get input for rows and columns of matrix A matrix A = Call input matrix with rows A, cols A rows B, cols B = Get input for rows and columns of matrix B matrix B = Call input matrix with rows B, cols B result = Call matrix_multiply with matrix A, matrix B Display result

If script is being run as the main program: Call main()
