I love studying with programiz, it's explained so simply :) I'm currently studying for my programming exam that's coming up, so thank you for the free lessons!

[@shijothomas4108]

ages represent the memory address of the zeroth array element. ie, ages+0 equals &ages[0]. Option D is the correct answer

[@stealthy_doctor]

Wonderful video! i think for the quiz it is D. &ages[0] because its like what was said where if you use just the name of the array it points to the head by deafult #include int main() { // Write C code here int arr[5] = {34,12,21,54,48}; int largest = *arr; for(int i = 0; i

[@phoneix24886]

When I was in college no internet resources were available. To search something simple as function pointers or array pointers we had to read books from Library. It was a tedious process. A college project could have taken months to complete. I love how modern education has evolved and become so interesting and simple.

[@BelalAlobieda]

I don't understand how you make it so easy like this. Thanks a lot

[@IDeserveToGetTortured]

Indeed!

[@emmanueljulius1827]

Ages represent the first element in the array, which is ages[0]

[@NyangwaKulwa]

Superb! I've liked the explanations for they are well understood.Thanks for making the c programmming knowledge accessible to everyone in need of it.

Plz try to upload the videos faster can't wait to learn any way ur teaching skills are mind blowing

[@hongkyulee9724]

Your video is really helpful to understand how a point arithmetic works and fundamentally what an array is

[@sushilgbp]

Quz answer is option D. #include int main() { int arr[5] = {5,10,15,20}; int largest = *arr; int i=0; for(i=0; i

[@18fatima15]

wouldn't it be better to start iterating the for loop from i=1

[@Paroseni.]

No because then you miss the first array element, as arrays start from value 0

[@TONY_GEORGE-25]

@@Paroseni. but the first element of that array is already assigned as the largest.

[@AliHk-qs8vm]

​@@Paroseni.you already included first array in this part ( int largest = *arr; ). So there is no problem to start the for loop from ( i = 1 ).

[@AliHk-qs8vm]

​@@18fatima15 I think you are right

[@rodolfoc.nascimento6301]

Amazing, the way you teach is incrible! I got pointers now, I admiti I had some dificult, thank you!

[@AIVerse3.0]

You are making good videos. I am thankful to you for this help. This is avery easy way to learn C language from very beginning.

[@light-warrior]

Task: #include int main() { int arr[5] = {34, 12, 21, 54, 48}; printf("First element in the array before change: %d ", arr[0]); int largest = *arr; *arr = 65; printf("Fist element in the array after the change: %d ", *arr); for(int i = 0; i < 5; i++) { if (largest < *(arr + i) ) { largest = *(arr + i); } } printf("Largest number of the array: %d ", largest); return 0; } Quiz answer: ages[0] represents the first element of the array, ages[1] represents the second element, and so forth, up to ages[4], which represents the fifth (and last) element of the array.

Thanks for your clear explanations :)

[@jonathanmawuena9081]

🎉❤❤❤i love the experience here. Keep it up ma'am

[@SaiSiddartha-l9o]

Answer is option D mam because the array name represents the address of the first element of the array

[@INFINITEonYouTube]

Amazing video even 2 years later.

Never thougth I would finally use pointers and make the challenge in this video

Q. In an array, int ages[5], what does ages represent? A. ages[4] B. ages[0] C. &ages[4] D. &ages[0]

[@AIVerse3.0]

I have to watch video first.

[@socialgamer23]

ages[0]

[@rickzalman4136]

ages is the base address of the array called ages. The name ages without a subscript always means &ages[0] or ages + 0 . It is the starting address of the array in memory, the address of the first element of the array.

[@anonymouszn4978]

Option D

[@adebulejohnykeyz4594]

B. ages[0]

[@thiagaodavez5465]

good good!

[@hardikbisht68]

as we are using the %p format specifier we are getting the hexadecimal value if we are using the %d format specifier it is giving different value i am just confused that which is the suitable format specifier for finding the address.

[@himanshushahi3795]

Use %u format spacifier for integer type memory address.

[@tibish]

%p is what you are looking for. the hexadecimal value is the acctual memory address where the value is stored.

[@aswinmanoj8681]

printf("Array Address: %p ", numbers); Why are we not using &numbers in this line of code? isnt 'numbers' supposed to show the value and '&numbers' supposed to show the address?

[@fanman2101]

numbers with brackets mean "the value of an element", numbers without brackets means "address of the first element"

[@socialgamer23]

Could anyone tell the difference between char*array[] = {"hi","hello","bye"} char ARRAY[] = {"hi","hello","bye"} ?

[@anic1716]

Second one is wrong, because you need a 2D array whereas you're only declaring a single-dimensional array in the second array

[@rickzalman4136]

Well the first one is an array of pointers and the second one is a pointer constant pointing to the starting address of that array. For example char* arr[]= { "Ann", "Ben", "Dana", "Elle" }; you have a array of 4 pointers pointing to the starting address of each string. The second one , char arr[]={"Anna", "Bob","Dana", "Jim}; Is a array , but you can use the array name as a pointer to the starting address of the array. arr points to the address of first element of the array called arr. It is the same as &arr[0] or arr +0. arr+ 1 is the same as &arr[1] , which points to address of element called "Bob" , arr + 2 same as &arr[2] , which points to the address of element callrd "Dana" and so on through the array.

[@ranjithn0605]

//char*array[] = {"hi","hello","bye"} //for the first one by using this we can get the output #include int main() { // Write C code here char* array[] = {"hi", "hello", "bye"}; for(int i=0; i < 3;++i){ printf("%s ", *(array+i)); } return 0; } //but the second one is a two-dimensional array so you have to use like this #include int main() { // Write C code here char ARRAY[][20] = {"hi", "hello", "bye"}; for (int i = 0; i < sizeof(ARRAY) / sizeof(ARRAY[0]); ++i) { printf("%s ", ARRAY[i]); } return 0; }

for memory addresses, I am supposed to get 0x(some set of numbers and upper/lowercase letters), but when I run the code at 1:53, I am just getting numbers and a repeated set of uppercase letters Ex: 1 = 000000452BEFF938 3 = 000000452BEFF93C 5 = 000000452BEFF940 7 = 000000452BEFF944 9 = 000000452BEFF948 does anyone know why this is?

[@adwaithanil3747]

well that was her system basically a cloud system and this is your system both will have a different memory location If I do it I will get some other output anyway be happy that you got hexadecimal values
