char turma[30],caminho[100];
printf ("Diga o nome da turma a ser cadastrado:\n");
scanf ("%[^\n]", &turma);//Já tentei com gets e fgets
getchar();//Já tentei sem esse getchar
printf ("\nAgora o caminho onde quer gravar a turma:\n");
scanf ("%[^\n]", &caminho);
getchar();
mkdir(caminho);
strcat(strcat(strcat(caminho,"/"),turma),".coe");

FILE *cadastro = fopen (caminho, "ab");

Hello, I am doing a work of the faculty of archive, this is the function of register of class, I have not put the board of students but this is not the point... The problem is that in the output, in so many ways that I have already put, the file created inside the folder either goes unnamed before the extension or is not created at all. I’ve tried even with the infamous gets() function and it didn’t work. What I want to do is enter the name of the class, then the name of the folder, create the folder and then merge the names to create the file inside the folder. Can someone help me?

Answer 1

you missed in the end

strcat(strcat(strcat(caminho,"/"),turma),".coe");
printf("%s", caminho);
FILE *cadastro = fopen (caminho, "ab");

it should be like this:

FILE *cadastro = fopen (strcat(strcat(strcat(caminho,"/"),turma),".coe"), "ab");

or placing inside the variable

strcpy(caminho, (strcat(strcat(strcat(caminho,"/"),turma),".coe"));

Dude, maybe instead of concatenating the name, you would pass the variable with the name of the directory, and the file as parameter to create it would be simpler.
