struct fish joe; puts("enter name:"); scanf("%s", joe.name); puts("enter species:"); scanf("%s",joe.species); puts("enter teeth:"); scanf("%i", joe.teeth); puts("enter age:"); scanf("%i", joe.age); catalog(joe); label(joe);

struct fish joe; puts("enter name:"); scanf("%s", joe.name); puts("enter species:"); scanf("%s",joe.species); puts("enter teeth:"); scanf("%i", joe.teeth); puts("enter age:"); scanf("%i", joe.age); catalog(joe); label(joe);

This can be done with one scanf call

it compiles but error after i press enter when i place the first input

This requires you to allocate memory. And a non const char pointer since you alter the content

Really, so many messages about structs?

that makes sense

Anonymous

chapter 5 is all about structs

Ilya

yea thats what they didnt explain at all in the book , i kinda just guessed it was something like that.

Which book do you use? Use Prata

Ilya

@MasterZiv you know

I have no idea what is yocto

Artöm

Because you didnt allocate memory for string fields

Ilya

Someone here works with GUI on C++?? Wich are the best IDE's for make GUI based on your experience?

Qt Creator, yes, and actually it is the only IDE we have

Artöm

Theyre important duh

yes i am creating a seperate examples as we speak to test this out

head first C, its good for beginners but they leave out some stuff , like how to deal with \n character in fgets

Anonymous

between that book , stackoverflow, google, youtube and the chat, i gather the information i need

Ilya

Show all code, using pastebin.com

head first has a whole series of different languages but its meant specifically for beginners, like coding for dummies

i never found a book where i didnt have to research externally to get a full understanding

but i am going to read ANSi C programming next , second edition

Ilya

yea that one

Read Prata, "C Premier", I suppose, it's name. Or, combine your stupid book with Harbison, Steel "Annotated C"

Why STL is introduced in c++?

MᏫᎻᎯᎷᎷᎬᎠ

What?!

Ilya

Why STL is introduced in c++?

Why not?

Ilya

Why STL is introduced in c++?

What is your question? Where could it be introduced else if not in C++?

Artöm

Why STL is introduced in c++?

It was good enough

Ilya

It was good enough

It was not because c++ was appended and adopted to some new features only to implement STL

Means it was good enough to work their asses to get it

when using scanf for ints stored in a struct, do you do something like stuct_Variable.&age

To get the address of a member use &structVar.Member or &ptrToStruct->Member

it compiles and runs, but doesnt work as intended

Anonymous

its doesnt seem like the scanf statement in the add_Student function is storing the information in the struct variables declared in the main.c

Can you show your structure definition?

Can you show your structure definition?

struct student{ char name[80]; int age; int grade; };

Ilya

struct student{ char name[80]; int age; int grade; };

For such functions void print_Student_Info(struct student stu){ it is better to pass structure by reference, that is, via pointer. void print_Student_Info(struct student *stu) also, better pass it as const void print_Student_Info(const struct student *stu){
