plz help me to add two matrices using pointers..
1>Take two integer matrices say a,b,and a result matrix c,and two integer pointers pa and pb.
2>Assign the start address of arrays to these pointers.
3>Now if p points to a then p+1 points to a and you can even access it as *(p+1) which is equal to a.
4>By the above mentioned process go on adding two matrices by using *(p+i) and store it in c.
For the purpose of adding a one dimensional array works well enough in representing a matrix. For more complicated operations though, it would likely be easier to define a matrix like int mat[rows][cols];
I don't know much about C, but I think it's something like this:
/* Create pointers */
int * matrix_one;
int * matrix_two;
/* Dynamically allocate memory for our matrices */
matrix_one = (int*) calloc(50, sizeof(int));
matrix_two = (int*) calloc(50, sizeof(int));
/* Free up the allocated memory */
It depends on how you matrix is defined as a datastructure.
Sometimes they are defined as one long array.
Then you can just add the array elementwise.
If they are defined as double pointers,
then you should loop through the entire matrices in the sameorder.
I have a DGV (dgvListOfJobs), populated from an SQL database to show the user a list of 'jobs' (i.e. rows). I also show 7 other DGV's (dgvMonday, dgvTuesday, etc) ...
I was wondering if it was possible to create a software like visual studio (in addition simple, obviously). We could program in vb.net, c ++, etc.
