我已经使用静态数组创建了正向差异表，但无法使用动态数组解决它，请帮我解决这个表。
这是静态数组的代码，但我需要动态数组
#include<iostream>
int main()
{
inti,noOfDifferenceColumns;
//j is no of columnds. Initially it is 2. One for x, and other for f(x).
int j=2;
//std::cout<< "Hello World!\n";
//std::cout<<"Hello Hello";
std::cout<<"Enter no of values for x: ";
std::cin>>i;
std::cout<<"Enter no of difference tables to be created: ";
std::cin>>noOfDifferenceColumns;
j+=noOfDifferenceColumns;
floatarray[20][20];
//Entering values of x
std::cout<<"Enter values for x: \n";
for(int a=0;a<2;a++)
{
for(int b=0;b<i;b++)
{
`enter code here`std::cin>>array[b][a];enter code here
`enter code here`std::cout<<"\n";
}
if(a==0)std::cout<<"Enter value for f(x): \n";
}
std::cout<<"\nPrinting values: ";
std::cout<<"\nPrinting x and f(x): ";
//condition is c<2 as the outer loop will run twice. Once to print x and then to print f(x)
for(int c=0;c<2;c++)
{
if(c==0) std::cout<<"X"<<"\n";
elsestd::cout<<"F(X)"<<"\n";
for(int d=0;d<i;d++)
{
std::cout<<array[d][c]<<"\n";
}
}
std::cout<<"Printing Difference Tables: \n";
int g=i-1;
for(int e=2;e<j;e++)
{
std::cout<<"Printing Difference Column: "<<e-1<<"\n";
for(int f=0;f<g;f++)
{
array[f][e]=array[f+1][e-1]-array[f][e-1];
std::cout<<array[f][e];
std::cout<<"\n";
}
g--;
}
}
