Write a program in C which asks the user to enter a string (max 100 characters) and then prints the number of vowels and consonants in the string. The program must use pointers to achieve this.

The code required to read a string is:

printf("Enter any string (max 100 characters with no spaces): ");

fgets(str, 100, stdin); //stored the user input ins str which is an array.

Some sample output: Enter a string (max 100 characters with no spaces): Computer

Number of Vowels in String: 3

Number of Consonants in String: 5

Extra: Also write a function which prints all the characters in upper case.
