Helllo, I'm a student from Russia and I'm learning computer sciense, I want to say you help me so much and I hope your chanell will progress much more, good luck!
hi, I'm hoping that you can also make a compilation of this C course, just like what you did in your java tutorial. btw, thank you for these amazing tutorials.
Thanks.i like how you explain it and going on details and explain where things are from or what is for, for example the first for(i) is rows and the seconds is columns(j). good job.
Hi! Great video! I have a question. How does the code change from this if I need for a user to input the size of rows and columns,and not be given like in this video? Any help would be great,tnx! :)
#include int main() { int rows, columns; printf("Enter the number of rows: "); scanf("%d", &rows); printf("Enter the number of columns: "); scanf("%d", &columns); int numbers[rows][columns]; for (int i = 0; i < rows; i++) { for (int j = 0; j < columns; j++) { printf("Enter the value for element [%d][%d]: ", i, j); scanf("%d", &numbers[i][j]); } } printf(" "); for (int i = 0; i < rows; i++) { for (int j = 0; j < columns; j++) { printf("%d ", numbers[i][j]); } printf(" "); } return 0; } In this example, we first declare the rows and columns variables, and then use scanf() to read in the values from the user. We then declare the numbers array using the values of rows and columns. Next, we use two nested loops to iterate over each element of the array and prompt the user to enter the value for that element using scanf(). Finally, we print out the entire array using two nested loops and the printf() function.
This is how you can calculate the length of an array in C. First, obtain the size of the entire array (in bytes) and then divide it by the size of a single element (also in bytes). Since all elements in an array are of the same size, you can use any element to perform this calculation, and the result should always be an integer representing the total number of elements in the array. For a 2D array, to find the number of columns, you can take the array for any row (a common practice is to use the first element of the array, i.e., numbers[0]). The size of this row (or columns array) is sizeof(numbers[0]). To get the size of a single element within the columns array, use sizeof(numbers[0][0]), which refers to the first element of the first row (or the column itself). Finally, the length (or number of elements) of the columns array is sizeof(numbers[0]) / sizeof(numbers[0][0]). This should give the same length for any row in the 2D array, as each row contains the same number of columns.
Declaring array mentioning number of rows and columns.Why calculating number of rows and columns then? If we add an extra row or or column manually editing the code then why need to calculate number of rows and coumns on such a way?
#include
int main()
{
// 2D array = an array, where each element is an entire array
// useful if you need a matrix, grid, or table of data
/*
int numbers[2][3] = {
{1, 2, 3},
{4, 5, 6}
};
*/
int numbers[2][3];
int rows = sizeof(numbers)/sizeof(numbers[0]);
int columns = sizeof(numbers[0])/sizeof(numbers[0][0]);
printf("rows: %d
", rows);
printf("columns: %d
", columns);
numbers[0][0] = 1;
numbers[0][1] = 2;
numbers[0][2] = 3;
numbers[1][0] = 4;
numbers[1][1] = 5;
numbers[1][2] = 6;
for(int i = 0; i < rows; i++)
{
for(int j = 0; j < columns; j++)
{
printf("%d ", numbers[i][j]);
}
printf("
");
}
return 0;
}
thanks bro, its much easier to understand than college.
This is better than Netflix. Im waiting every new episode.
This was so helpful! I am an IT student and was having trouble understanding 2D arrays. This is the best video I found .

Ну как сдал?
BRO this was a game changer. seriously, thank you
This is one of best language learning channel tutorial i know
hi, I'm hoping that you can also make a compilation of this C course, just like what you did in your java tutorial. btw, thank you for these amazing tutorials.
fery good fideo vro keep it in the up
Thanks for helping me out. Greetings from Serbia
great work keep it up
🤓
Thanks bro u cleared my doubt ❤
Thanks.i like how you explain it and going on details and explain where things are from or what is for, for example the first for(i) is rows and the seconds is columns(j).
good job.
What my lecturer does in 2 hours you do it in 5minutes😂
Can you make a Django course soon? Thats what I'm really waiting for!
hi, can we use:
# include
# define rows
# define columns
and then use these defined sizes in our array and loop?
Thank you ❤
DONE❤❤
good vid!

@@farisraid7588 Thanks mate
thanks for the video
Great!
It took all the way up until I saw "print" to realize this wasn't C++. T_T
Can you create a tutorial on how to create a website. Like what program to use and what languages you need to know .Would be a great video
Can anyone explain why to get the size of column we need to specificy [0] then divide to [0][0]???

yeah i was thinking the same. and for now i am not interested on it but thanks to @heitor4191 i think i got it better.
why does my code not run unless i add in the
printf("rows: %d
", rows);
printf("columns: %d
", columns);
it runs but you cant see it. prontf is just to show you it happening. but can happen and dont show you what is done.

Can u plz do the same for Android
Is there is any videos about data science ???
Where's malloc?????
It would be better if u spaced these out over a few days instead of uploading them all at once.
?
Bro the index of 2D arrays don't start at 0?
pls some java tuts?
Please put Arabic subtitles in TH-cam settings in your videos
Allahuuu aknarrrr
What if he isn't Arabic and doesn't know this language?
It wont print, and i dont know if its the shitty online compiler im using.
