This program takes string input from the user and stores in variable line.
Initially, the variables vowels, consonants, digits and spaces are initialized to 0.
When the vowel character is found, vowel variable is incremented by 1. Similarly, consonants, digits and spaces are incremented when these characters are found.
Finally, the count is displayed on the screen.
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
