Hi,
A) Create 2D array of size[4][3] Then insert values to the 1st column of the array from the keyboard and assign 0 for all the other elements.

B) Write a function called dispalyArray() to display the content.

void dispalyArray (int arr[][4], int rows, int columns);

Please help me..

What I have tried:

I do not know much about arrays. So trying to learn about arrays from the beginning.

And what does your course say about arrays, especially 2D ones?

Because it looks like your homework I give you the link to tutorial about arrays.

And some additonal tips:

C++

int arr[4][3] = {0};//init a 2-dimensional array with size of 4 x 3 with value of 0
arr[1][0] = 3;//setting a value at position
int value = arr[1][0];//getting the value

For output on the screen you can use the print command.

With that knowledge it really should be very easy.

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
So, start working. If you are stuck on a specific problem, show your code and explain this exact problem, we may help.

Here is links to references books on C and C++ by the authors of the languages. Note than C is the ancestor of C++, so knowing C is always useful with C++.

Solution 3

If you are really interested in C++ arrays, then have also a look at std::array[^] class.
