Galera helps me: the exercise I'm trying to do is 4. Write a program where:

a) Read a character that must be one of the alphabet vowels, which may be uppercase or lowercase.

b) If a function is found in which you check which vowel has been read, print one of the following messages, depending on the case:

1st vowel,

2nd vowel,

3rd vowel,

4th vowel,

5th vowel or

Another character

Can anyone tell me what I'm doing wrong?

#include<stdlib.h>
#include<locale.h>

char VogaLida (char Vogal [], int TamanhoVetor);


int main (){

    setlocale(LC_ALL, "PORTUGUESE");

    char Vogal [] = {'a', 'e', 'i', 'o', 'u'};
    char VogalLida;

    printf("Informe uma vogal: ");
    gets(Vogal);

    VogalLida = VogaLida(Vogal, 5);

}

char VogaLida (char Vogal [], int TamanhoVetor)
{
    int i = 0;

    for (i = 0; i < 5; i++){

        if (i == Vogal[0]) {
            Vogal[0] = 'a' | 'A';
            printf("1ª Vogal\n");

            return 0;
        }
        else if (i == Vogal[1]){
            Vogal[1] = 'e' | 'E';
            printf("2ª Vogal\n");

             return 0;
        }

        else if (i == Vogal[2]){
            Vogal[2] = 'i' | 'I';
            printf("3ª Vogal\n");

             return 0;
        }


        else if (i == Vogal[3]){
            Vogal[3] = 'o' | 'O';
            printf("4ª Vogal\n");

             return 0;
        }

    }

        return 0;
}

Your program is bugged, the logic is in trouble.

You are reading a character with the function gets() and placing in the vector that had its Vogal characters, you only need to read one character.

After you call the VogalLida method that checks the vowels however you use i which is an integer to make the comparisons inside the for block.

...

Actually, there is no way for me to explain everything here, so follow the reasoning:

1) According to your prinf () you only want to read a letter to check if it is a vowel. Then try getc() and save it to a char variable.

2) Make the VogalLida(char vogal) function with the following body:

void VogalLida(char vogal)
{
    switch(vogal)
    {
        case 'a': printf("1ª Vogal\n"); break;
        case ...;
        default: printf("Nao eh vogal\n");
    }
}

Now just implement the other cases, the way you implemented you used many resources and ended up embolando the logic.
