4. Create following functions, and test use given main function.
int** create2DArray(int row, int column): return a 2d dynamic int array with given row
and column.
void populate(int** array, int row, int column, int start): initialize the given dynamic
2d array use number from start, and increase one every element.
void print(int** array, int row, int column): print every element from given dynamic 2d
array.
void delete2DArray(int** array, int row, int column): which delete given dynamic 2d
array from the heap.
Use pointer arithmetic for every function.
Use following main() to test your class.
int main(){
int **a = create2DArray(3,5);
populate(a,3,5,10);
print(a,3,5);
delete2DArray(a,3,5);
cout<<endl;
a = create2DArray(2,6);
populate(a,2,6,22);
print(a,2,6);
delete2DArray(a,2,6);
}
Output from given main function:
10 11 12 13 14
15 16 17 18 19
20 21 22 23 24
22 23 24 25 26 27
28 29 30 31 32 33
5. Q5: Write a function for given main function
void bargraph(int n)
which takes an integer n and print the bar graph based on the digit of given integer.
Use pointer arithmetic and Dynamic Array if you would like to use array.

int main(){
bargraph(12945);
bargraph(6789102);
}
Output from given main function:
