Count Capital and Small Letters in C

In this article I would like to share with you a code that I wrote using C language what this program will do is to ask the user to type a word or a sentence and then our program will count the number of occurrence of capital and small letters from the word or sentence being type or provided by our user of our program.

If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

   printf("\n\n");
   printf("\nEnter a sentence :=> ");
   gets(ch);

   while (ch[i] != '\0') {
        
      if (ch[i] >= 'A' && ch[i] <= 'Z')
         upper++;
      if (ch[i] >= 'a' && ch[i] <= 'z')
         lower++;
