You are responsible for writing an extension for the MS Word application, which is responsible for counting the lowercase letters, uppercase letters and digits in a given text, and reporting these numbers to the user. Given below is the program implementing that extension. Fill in the spaces. Do not use ctype.h library. Hint: In ASCII, each char corresponds to a number. The digit characters 'O' through '9; the uppercase characters 'A' through 'Z', and the lowercase letters 'a' through 'Z' are consecutive. int main() { char text[100]: intc, i=0, lowerCount=0, upperCount=0, digitCount=0; printf("enter text: "); gets(text); while (text[i] != '\0') { = (int) text[i]; Il check if text[i] is lowercase (3 pts) lowerCount++; else if ( ...... ) // check if text[i] is uppercase (3 pts) ......; // update the correct counter (2 pts) else if ( ...... ) // check if text[i] is a number (3 pts) digitCount++; // update the correct counter (2 pts) Il complete (3 pts) } printf( ......... ); // report the 3 counters to the user (4 pts)
