This is better than Netflix. Im waiting every new episode.

[@doochow9962]

This was so helpful! I am an IT student and was having trouble understanding 2D arrays. This is the best video I found .

[@republicofserbia]

Thanks for helping me out. Greetings from Serbia

[@itchybakerzz5101]

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.

[@user-bh8xz4xy7o]

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!

fery good fideo vro keep it in the up

[@diusepausm]

This is one of best language learning channel tutorial i know

[@stanleywambani860]

What my lecturer does in 2 hours you do it in 5minutes😂

[@celestialcamel1959]

Can you make a Django course soon? Thats what I'm really waiting for!

[@yigitdogan2k]

hi, can we use:
# include
# define rows
# define columns
and then use these defined sizes in our array and loop?

[@na0miiii__]

good vid!

[@tescenmo_Ed]

Thank you ❤

[@umachandeeswari2942]

Great!

[@umutaydn6184]

thanks for the video

[@joeface448]

It took all the way up until I saw "print" to realize this wasn't C++. T_T

[@javenlim5514]

why does my code not run unless i add in the
printf("rows: %d
", rows);
printf("columns: %d
", columns);

[@andrejpoljakovic5482]

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! :)

[@farisraid7588]

#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.

@@farisraid7588 Thanks mate

[@sachinsaagar7531]

Can u plz do the same for Android

[@SHADOW-du7yf]

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

[@magns2623]

Is there is any videos about data science ???

[@luci1368]

Bro the index of 2D arrays don't start at 0?

[@javacoder2134]

pls some java tuts?

[@rendezvousonmemorylane]

It would be better if u spaced these out over a few days instead of uploading them all at once.

Allahuuu aknarrrr

[@civicaverage796]
