Question

Q4. Write an algorithm, draw the flowchart and write a C++ program to • Read the Number and Letter from the user • Check the number and letter then print the corresponding month name as given in Table Q4 using IF ELSE STATEMENT. Table: Q4 Number and Letter Month Name JANUARY 2 F FEBRAURY 3 M MARCH 4 A APRIL Other numbers Invalid Input 1J Sample Output: Enter the value of number:1 Enter the value of letter:) JANUARY Algorithm: Flowchart: Program:

Answer 1

Algorithm Step1 : Start Step 2: Declare variables for monthNumber and monthletter Step 3: Read values monthNumber and monthLetter Step 4: If monthNumber = 1 and monthLetter = 'P Display JANUARY Step 5: Else If monthNumber = 2 and monthLetter = 'F' Display FEBRUARY Step 6: Else IF monthNumber = 3 and monthLetter = 'M Display MARCH Step 7: Else If monthNumber = 4 and monthLetter = 'A Display APRIL Step 8: Else Display "Invalid Input" Step 9: Stop

FlowChart

Start accept monthNumber and monthLetter Yes monthNumber = 1 and monthLetter='J JANUARY No Yes monthNumber = 2 and monthLetter = 'F FEBRUARY No Yes monthNumber = 3 and month Letter = "M" MARCH No Yes monthNumber = 4 and monthLetter = 'A' APRIL Invalid Input Stop
