I’m making a login screen, but my code is giving error:
Conflicting types for 'login'.
I’m a beginner in the area and I’m not able to understand what to do to fix this, someone could help me?
typedef struct{
char login[30];
char senha[30];
} usuario; usuario u[0];
void tela_login()
{
FILE *login;
login = fopen("login.txt", "a"); //"a" para adicionar no txt
if (login == NULL) {
printf("\nO arquivo não foi aberto!");
exit(0);
}
system("cls");
char login[30];
char senha[30];
int contador;
for(contador = 1;contador<=3;contador++){
system("cls");
strcpy(u[0].login, "admin");
strcpy(u[0].senha, "202020");
printf("Digite o login do usuario ADMIN: ");
fgets (u[0].login,30, stdin);
printf("Digite a senha do usuario ADMIN: ");
fgets (u[0].senha,30, stdin);
while(fgets(u[0].login && u[0].senha,30, stdin) != NULL) {
if((strcmp(login,u[0].login)==0) && (strcmp(senha,u[0].senha)==0)){
printf("Seja bem vindo");
}else{
printf("Login e/ou senha invalidos, tente novamente!");
}
}
printf("Login e/ou senha bloqueado temporariamente");
}
fclose(login);
}
After all
login
is a FILE or char array?FILE *login;
andchar login[30];

FILE *login is for the creation of the file and then manipulation and char login[30] is to inform the size of the vector used for the login, but you think the two can not have the same name because they are conflicting? I tried to modify it once but had trouble compiling the rest of the code, so I’m getting suggestions because the more I move the worse it gets and being a beginner I don’t know exactly what to do

You cannot give the same name to different things. This is basic in programming.
