The objective of this exercise is to analyze a given string and count various types of characters in it. Specifically, you are required to count the number of vowels, consonants, uppercase characters, lowercase characters, spaces, and digits in a given C-string. Requirements Data Structures The Character_Counts struct is defined with fields to hold the counts for vowels, consonants, uppercase and lowercase characters, spaces, and digits. Function Declarations and Definitions Implement analyse_text that takes in a character array (C-string) and returns a Character_Counts struct populated with the counts. The print_counts function is already implemented and takes a Character_Counts struct as an argument to print out the various counts. Main Function In the main() function, a buffer array is defined, and user input is read into this buffer. The analyse_text function is then called with this buffer as an argument, and its return value is stored in a Character_Counts struct. This struct is then passed to print_counts to display the counts.
