Handling Whitespace in scanf

When the user presses space or enter in the console,
this puts ' ' and '\n' whitespace
characters into stdio respectively.
When reading an int* with %d or float* with %f, scanf
skips any leading whitespace.
However, %c for char* extracts whitespace characters.

Example Problem

Say the user enters " 70 f", and we want to read 70 and f into int and char respectively:

int x; char c;
scanf("%d", &x); // OK,  x = 70
scanf("%c", &c); // BAD, c = ' '

Instead of reading f, we read a space, because %c does not skip leading whitespace. Solution:

scanf(" %c", &c);

The leading space before %c matches any whitespace of any length.

@stiff lindenwait nvm, what is that supposed to solve

[stiff linden]

i literally can't see what you posted

because you posted a screenshot

i have 3 printf + scanfs

and for some reason its just breaking

                    printf("Olympia - Jardim Zoologico\nInserir novo animal\n",i++);
                    inserir[i].numero=i;
                    printf("Introduza o nome: ");
                    fflush(stdin);
                    scanf("%s",inserir[i].nome);
                    //gets(inserir[i].nome);
                    printf("Introduza a especie: ");
                    fflush(stdin);
                    scanf("%s",inserir[i].especie);
                    //gets(inserir[i].especie);
                    printf("Introduza a idade: ");
                    fflush(stdin);
                    scanf("%d",inserir[i].idade);
                    printf("Introduza a data de entrada  (dd/mm/aa) : ");
                    scanf("%d/%d/%d",inserir[i].dia,inserir[i].mes,inserir[i].ano);
                    printf("Prima ENTER para sair");
                    getchar();
                    goto gestaoanimais;
                break;```

i know its not in english but just have a look at the commands

[stiff linden]

goto

[wind karma]

is that bad

my 2 weeks experience in C

[jolly mist]

goto is heavily frowned upon by most people

[wind karma]

and what would i do to replace a goto statement

[jolly mist]

depends how you are using the goto

[wind karma]

going to a menu

(back to a menu)

[jolly mist]

you would need to restructure your code, however you do that is up to you

[stiff linden]

make it into a function and use return

[wind karma]

ohh yeah that'd work, but how about why my scanf doesnt work?

[stiff linden]

i have no idea what you mean by "breaking" but

scanf takes pointers

so scanf("%d",inserir[i].idade); probably isn't right

[wind karma]

yes its not

[stiff linden]

i don't know what inserir is but probably you meant scanf("%d", &inserir[i].idade);

[wind karma]

so i do have to use a & with structs

[stiff linden]

no

you have to use & when you want a pointer

[wind karma]

its still not working (just exits the console after ^)

                scanf("%s",insert[i].name);
                printf("Introduce the species: ");
                scanf("%s",insert[i].species);
                printf("Introduce the age: ");
                scanf("%d",&insert[i].age);
                printf("Introduce the date  (dd/mm/aa) : ");                    
                scanf("%d/%d/%d",&insert[i].day,&insert[i].month,&insert[i].year);```
