C++ DMA Charater Arrays?

Question

How would I DMA a 2D character array, when my point is created before hand.

The pointer is created in a class. I need to create the MDA'd array in my constructors.

Answer 1

please write in details wat u actually want
wats the use of creating an array created before hand

Answer 2

the 1st set of code is as follows: int MyList[40 8]; int MyList[0] = {a million,2,3,4}; int MyList[a million] = {3,4,5,6,2,3,a million}; you have decalred an integer array of length 40 8, yet to each element you're assigning an int array. that's not suited. The project must be of the style MyList[0]=2; added different declarations for MyList is there. So this code isn't conceivable. the 2d set of code is given under: int *record[40 8]; int record[0] = {a million,2,3,4}; int record[a million] = {2,3,4,5,6,7,8,9}; The mening of the 1st fact is record is an array of 40 8 preparation that ought to integer, in view that [] has a extra physically powerful priority than *. for sure that's not what you prefer. What we prefer is that we ought to constantly declare a pointer to a ten element integer array, assuming that the optimal length of a subarray is 10, on an identical time as 40 8 such subarrays are to be saved with documents. int *(MyList[10]);// right here MyList is a pointer to an array of 10 integers, the max length of the sub array. Now we are in a position to create the subarray as int ML1[10]={a million,2,3,4}; int ML2[10] = {2,3,4,5,6,7,8,9}; ML1 incorporates the handle of array {a million,2,3,4} and that's often assignd to the pointer MyList[0] ML2 incorporates the handle of array {2,3,4,5,6,7,8,9} and that's often assignd to the pointer MyList[a million]. similary we are in a position to assign different sub arrays. you will discover that the discern 40 8 does not look everywhere in our code. that's not needed in view that, the reminiscence is allotted as much as we prefer, one with the aid of one. Use of this code, in assigning documents to the arrayand showing the assigned documents is given interior of right here code. ------- code ------- # incorporate #incorporate void significant() { int *(MyList[10]);/* MyList is pointer to an array of 10 int*/ int ML1[10]={a million,2,3,4};/* we at the instant are not totally using the ability of 10 int*/ int ML2[10] = {2,3,4,5,6,7,8,9}; /* further you are able to declare different individual arrays int ML3[10]={11,12,13,14}; .. .. */ int i,j,jmax; MyList[0] = ML1;/* assigns the handle of sub array a million to MyList[0]*/ MyList[a million] = ML2; /* further you are able to assign different array handle MyList[2]=ML3; etc */ clrscr(); for (i=0;i<2;i++) { if(i==0) jmax = 4;/* length of MyList[0] array*/ if (i==a million) jmax = 8;/* length of MyList[a million] array*/ /* further supply the sizes of alternative arrays if(i==2) jmax = 4; etc. */ for (j=0;j
