comparing against both lowercase and uppercase.

Happy Thanksgiving if it applies. I am trying to create a function I will be able to use in the future. The function should be able to accept a char array and code it. (I am not finished with the code part)

int codetut(char *codeit){
int x,y = 0;
char tmparry[strlen(codeit)];
while(codeit[x] != '\0'){
    if((codeit[x] >= 'a' && codeit[x] <= 'z') || (codeit[x] >= 'A' && codeit[x] <= 'Z')){ //Set to look for capitals and commons
        if((codeit[x] == 'a' || codeit[x] == 'e' || codeit[x] == 'i' || codeit[x] == 'o' || codeit[x] == 'u') && (codeit[x] == 'A' || codeit[x] == 'E' || codeit[x] == 'I' || codeit[x] == 'O' || codeit[x] == 'U')){ // set to look for vowels
        tmparry[y] = codeit[x];

        x++,y++;
        }else{

        x++,y;
        }
    }else{
    tmparry[y] = codeit[x];
    x++,y++;
    }
}
printf("%s",tmparry);
return 0;
}

I was looking here how to validate both lowercase and uppercase letters. Unfortunately I did not find what I was looking for.

Question:

  1. Is there a better way to compare the pointer to both uppercase and lowercase versions?

Just one request, if you know a post that will help me please point me to it.

Convert the character to lower first, then do the comparisons.

tolower is the method for this. See e.g. c - convert a mixed-case string to all lower case
