Learning C Programming Lesson 32: Pointers Array and Structure

[TuggieGameReviews]

How can't you people see? Do you know how to enlarge the window?

[PoseidonHermes]

There are lots of errors in these videos, on the pointer part as well as the structure part!!

I don't think this guy is a qualified teacher or experienced programmer

[MrUsman4040]

What will be the type of ptr_b?

int *ptr, ptr_b;

ok...i have a question...if i would like to read the names of a family(for example for 4 people)..i set the structure and then in main i write...struct family array[4];...but how should i read the exact names...like this??

for(i=0;i<=3;i++){ gets(array.name[i]);/*or with scanf...??*/

}...plz answer...

[Stung5]

@djcrank7 try the predefined gets() function, you making a simple task more complicated than it needs to be.

why define a pointer only to assign it a string value of "good"? shouldnt a pointer just point to some vaule in memory....why didnt you just use a variable....dont understand why you used pointer here

[TheCosmicFrog]

@pagola Because in C there is no variable that can hold a string. A string is instead held in an array of chars (or a "character array").

I believe C++ has a variable for holding strings though.

[Stung5]

@TheCosmicFrog yeah C++ has its own string library. It's still a C-style string though; but, you don't have to waste time writing the same general functions over and over again.

[nickrohn93]

@TheCosmicFrog Well if you look at c++'s standard lib they use char type :P

[TheCosmicFrog]

@nickrohn93 Never looked too deeply into C++ to be honest. Ran away from C as fast as I could and embraced Java. It's a sad realization that some day I will need to go back to C/C++ on my hands and knees and beg for its forgiveness.

[Stung5]

@pagola hahah, what he did was fine. An array is a pointer. It points to a mem loc which can then hold data, which in this case is a 4 ASCII characters.

can u zoom it in please???? i really need it! please....

[hommyhom]

these videos are saving my life thanks a lot umicom. It is hard to find "advanced" C tutorials like this. Many of the more difficult concepts are mostly explained with C++ videos.
