int count[2];
ptr = (char *)malloc(200);
printf("ENTER INPUT STRING\n");
ptr = gets(ptr);
CountVowCons(ptr, count);
printf("\nNO OF VOWELS:%d \nNO OF CONS: %d",count[0], count
[1]);
getch();
}
CountVowCons(char *ptr, int *count)
{
int Vowcount = 0, Conscount = 0;
while(*ptr != '\0')
{
if((*ptr == 'a') || (*ptr == 'A') || (*ptr == 'e') ||
(*ptr == 'E') || (*ptr == 'i') ||
(*ptr == 'I') || (*ptr == 'o') || (*ptr == 'O') ||
(*ptr == 'u') || (*ptr == 'U'))
{
Vowcount++;
}
else if((*ptr >= 65 && *ptr <= 90) ||
(*ptr >= 97 && *ptr <= 122))
{
Conscount++;
}
ptr++;
}
*count++ = Vowcount;
*count = Conscount;
count--;
