I struggling with understanding how to reach the data inside array of arrays.
I have an array of size n where each element is an array of size 2 so it looks like this:
[[0,1],[0,2],…,].
This array is passed to a function as
function(int** arr, int n, int* arrColSize)
How can I do a compare on the arrays inside the array?
for example I want to do something like
if (arr[0] == [0,1]))
Here it should return true

This question already has answers here: How can i create an n-dimensional array in c (2 answers) Correctly allocating multi-dimensional arrays (3 answers) Closed 23 hours ago. Is it possible to define multidimensional arrays from user input in C where the user could specify the number of dimensions, eg: 1 => arr[x] 2 => arr[x][x] […]

How i get array elements from user in C? I don’t how many elements user will give?
once user may give 1 2 3 4 5
next user may give 12 3 21
next user may give 12 33 2 2 1 2 34 5
like this i don’t know size of array

For example, consider the following code. It is a function that outputs a histogram of an image.

The first array is multiples of 5, second array is multiple of 9. I was able to store the input but the printed array seems wrong as it did not print my supposed numbers. Any kind soul could help and provide feedback

Suppose I have a 2d array like so:

I’m making a program which automates Luhn’s algorithm; it takes every other number of a credit card starting with the first one, multiplies them by two, and adds the multiplied the added numbers together. I’ve not finished, but have encountered a problem called “stack smashing detected”. Can anybody offer help or advice?

I cant get this function to work properly. it crashes at the for loop. i post only the excerpt and the variables.

I am doing a Registration code in C, which basically can input multiple accounts.
Now, what I want is to access that specific account through a Log-In function where (Pass == LogIn Pass).

Here are two possible ways to initialize an array, one using list initialization:
