Step by Step solution about How to resolve the algorithm The Name Game step by step in the C programming language

This C code prints a version of the "banana-fana" song for a list of names. Here's a detailed explanation:

• Header Files:

  • The code includes two header files:
    • <stdio.h> for input/output functions like printf.
    • <string.h> for string manipulation functions like strdup and toupper.

• print_verse Function:

  • This function takes a string name as input and prints a personalized version of the "banana-fana" song for that name.
  • It performs the following steps:
    • Creates two character pointers, x and y, to manipulate the name.
    • Initializes three integer flags b, f, and m to 1. These will be used to print "bo-", "fo-", or "mo-" based on the first letter of the name.
    • Duplicates the input name into x using strdup and converts the first letter to uppercase. The rest of the letters are converted to lowercase.
    • If the first letter of the name is a vowel ('A', 'E', 'I', 'O', or 'U'), it creates another copy (y) with the first letter in lowercase. Otherwise, y points to the second character in x.
    • Adjusts the three flags b, f, and m to 0 if the first letter of the name is 'B', 'F', or 'M' (case-insensitive).
    • Prints the song lyrics, replacing "name" with the modified x and y strings, and adjusting the prefixes "bo-", "fo-", and "mo-" based on the flag settings.

• main Function:

  • Initializes an array names with six names.
  • Iterates through the names array, calling the print_verse function for each name to print the personalized song lyrics.

• Code Execution:

  • When the program runs, it prints the "banana-fana" song for each name in the names array. The output will look something like this:

GARY, gary, bo-ary
Banana-fana fo-ary
Fee-fi-mo-ary
GARY!

EARL, earl, bo-earl
Banana-fana fo-earl
Fee-fi-mo-earl
EARL!

BILLY, billy, bo-illy
Banana-fana fo-illy
Fee-fi-mo-illy
BILLY!

FELIX, felix, bo-elix
Banana-fana fo-elix
Fee-fi-mo-elix
FELIX!

MARY, mary, bo-ary
Banana-fana fo-ary
Fee-fi-mo-ary
MARY!

SHIRLEY, shirley, bo-hirley
Banana-fana fo-hirley
Fee-fi-mo-hirley
SHIRLEY!
