C array programs on searching vowels - consonants - words and punctuations

This is the continuation of character type array.  Here is another C program on string.

Take a sentence from the user and count the number of vowels, consonants, punctuations, and words in the sentence.

#include< stdio.h >

#include< string.h >

void main()

{

 char ch [50];

 int i,vowel=0,cons=0,space=0,punc=0,word=0;

 clrscr();

 puts("Enter the string:-");

 gets(ch);

 for (i=0;i< strlen (ch);i++)

 {

 if((ch[i]=='a')||(ch[i]=='e')||(ch[i]=='i')||(ch[i]=='o')||

   (ch[i]=='u')||(ch[i]=='A')||(ch[i]=='E')||(ch[i]=='I')||

   (ch[i]=='O')||(ch[i]=='U'))

    vowel++;

 else if((ch[i]==',')||(ch[i]=='.')||(ch[i]==';')||(ch[i]==':')

            ||(ch[i]=='"')||(ch[i]=='?'))

            {

             punc++;

             word++;

             }

 else if(ch[i]==' ')

            {

             space++;

             word++;

             }

 else

            cons++;

 }

 printf("Total vowels in the string is :-%d.",vowel);

 printf("\nTotal consonants in the string is :-%d.",cons);

 printf("\nTotal spaces in the string is :-%d.",space);

 printf("\nTotal words in the string is :-%d.",word);

 printf("\nTotal punctuations in the string is :-%d.",punc);

 getch();

 }
