My strcpy isn't working even if I allocate memory to my pointer struct

Question

I tried to allocate memory to my struct but it didn't work. Here is the piece of my programme where it goes wrong (also the declaration of the structs).

struct ptr {
    int tel;
    char nome;
    struct ptr *prox;
};

struct reg{
    char letra;
    struct ptr *inicio;
};

struct reg agenda[26];

agenda[l].inicio = (struct ptr*)malloc(sizeof(struct ptr));
agenda[l].inicio->prox = (struct ptr*)NULL;
strcpy(agenda[l].inicio->nome,nome);

Answer 1

Try changing the nome char to a char pointer. Also before strcpy you have to allocate memory for the pointer.

struct ptr {
    int tel;
    char *nome;
    struct ptr *prox;
};

struct reg{
    char letra;
    struct ptr *inicio;
};

struct reg agenda[26];

agenda[l].inicio = (struct ptr*)malloc(sizeof(struct ptr));
agenda[l].inicio->prox = (struct ptr*)NULL;
agenda[l].inicio->nome = (char*)malloc(MAX_NOME_LENGTH);
strcpy(agenda[l].inicio->nome,nome);

Of course change MAX_NOME_LENGTH to the maximum size of the string.
