C Program to Count Vowels and Consonants in a String using Pointer

#include <stdio.h>
int main()
{
    char str[100];
    char *p;
    int  vCount=0,cCount=0;

    printf("Enter any string: ");
    fgets(str, 100, stdin);

    //assign base address of char array to pointer
    p=str;

    //'\0' signifies end of the string
    while(*p!='\0')
    {
        if(*p=='A' ||*p=='E' ||*p=='I' ||*p=='O' ||*p=='U'
        		||*p=='a' ||*p=='e' ||*p=='i' ||*p=='o' ||*p=='u')
            vCount++;
        else
            cCount++;
        //increase the pointer, to point next character
        p++;
    }

    printf("Number of Vowels in String: %d\n",vCount);
    printf("Number of Consonants in String: %d",cCount);
    return 0;
}
