Hi all, I was wondering if someone could point me to the right direction on how to use strcpy on a 2D array. The names of the students are suppose to Strcpy() from a 2D array

You can. That's all the same you need for 1000 (rows*cols, if rows is 50 and cols 20) ints. The problem is, that will be a one dimensional array of 1000, like: int array[1000] which you could use both to store a matrix, but you will keep having to do some weird math in order to find your elements. That's awkward for the programmer and most ...

Nov 13, 2006 · I need to use a 2D array of chars. The first field (rows) is set at 20480. The second field (columns) needs to be set at runtime (4096 being one possible value). The size of the 2D array will be too big to fit on the stack, so it needs to be global, putting it on the heap. It is also too large to be created dynamically with a call to malloc().

If you have a 2D array for some reason and you want to treat it as a 1D array, yu don't ned to do anything except cast Code: double matrix[4][4]; // 2d matrix double *mtxptr = (double *) matrix; // 16 element 1 d array using the same memory buffer mtxptr[15] = 0.0; // set the last element to 0.0

Hi! I am new to C programming. I am trying to write a program that involves finding unique values in a 2D array and saving them in a separate array. The values in the 2D array are not sorted. Also, a value and its negative should be considered the same. For example, if the 2D array is

Well first of all in order to pass a 2d array you must define in main 2 pointers (int** temp_array, you must also assign to variables (for example i and j) the size of rows and columns. Now since you are using a void function to do the population , you must pass the array, the rows and the columns to that function (array as reference and rows ...

But that's not possible in C because array indices must be of integer type. You have to either use two different arrays (one for the float, the other for the frequency) connected with the index (the index of the float number in your numbers array is the same as the index of the corresponding frequency in the comp array) or create your own data structure where you can store float …

Reading a file and storing it as a 2d Array. Hi everyone, I have been given the assignment to create a program to find the the least squares method of fitting a straight line function to one of two data sets given to me in a txt format. the file has an unknown number of data points.

I suggest that you start with a simpler program: a program that will read a string of up to length 5 (hence an array of 6 char because of the null character), pad with spaces, then print the string within quotes (so you can tell that you correctly padded it with spaces).

I actually searched the phrases "2d char array" "array 2d char c" "initialize 2d array char c" "initialize 2d array" etc for about the last hour before I decided to bother anyone...FYI great thread ill have a look thx
