A listing is a set of comparable or several types of information parts.
Dynamic Language like python can retailer totally different information varieties in the identical listing, however for statically typed language like C++, a listing means a set of comparable information varieties. Each listing merchandise might be accessed by its indices, and for a lot of the languages (python, java, C++, and so on.) indices begin from 0.
An array is similar because the listing for dynamic language, however for a language like C++ the place for a listing dynamic reminiscence allocation is finished by the compiler, for array consumer has to do it manually.
Implementation of Checklist inside Checklist utilizing C++:
C++
#embrace <bits/stdc++.h>
utilizing namespace std;
int most important()
{
listing<listing<int> > ListofList;
listing<int> insertedList;
for (int i = 1; i < 5; i++) {
insertedList.push_back(i);
}
ListofList.push_back(insertedList);
ListofList.push_back(insertedList);
for (auto it = ListofList.start();
it != ListofList.finish(); it++) {
for (int j : *it)
cout << j << " ";
cout << endl;
}
return 0;
}

Implementation of Checklist inside Checklist utilizing Python:
For Dynamic Language like python Create 2 or extra lists and append them inside one of many lists, And it’ll create a listing inside a listing,
Python3
list_1 = [1, 2, 3, 4]
list_2 = [4, 7, 8, 9]
list_3 = [3, 1, 4, 7]
list_4 = [3, 5, 7, 11]
list_1.append(list_2)
list_1.append(list_3)
list_1.append(list_4)
print(list_1)
|
Output
[1, 2, 3, 4, [4, 7, 8, 9], [3, 1, 4, 7], [3, 5, 7, 11]]
Creating array contained in the array in C:
However for statically typed language like C one should predefine every part like the information sort of the array which shops one other array.
For instance, to create a 1D integer array inside one other array, firstly, the primary array ought to retailer (int*) datatype then solely, one other 1D array might be saved/created inside that array.
Observe: Following the identical manner an array might be created inside one other array in C++ additionally.
C++
#embrace <bits/stdc++.h>
utilizing namespace std;
#outline dimension 5
int most important()
{
int** out_array = (int**)malloc(dimension * sizeof(int*));
int* temp1 = (int*)malloc(dimension * sizeof(int));
int* temp2 = (int*)malloc(dimension * sizeof(int));
for (int i = 0; i < dimension; i++) {
temp1[i] = i;
temp2[i] = i;
}
out_array[0] = temp1;
out_array[1] = temp2;
cout << "After Creating array inside array " << endl;
for (int i = 0; i < 2; i++) {
for (int j = 0; j < dimension; j++) {
cout << out_array[i][j] << " ";
}
cout << endl;
}
return 0;
}

C
#embrace <stdio.h>
#embrace <stdlib.h>
#outline dimension 5
int most important()
{
int** out_array = (int**)malloc(dimension * sizeof(int*));
int* temp1 = (int*)malloc(dimension * sizeof(int));
int* temp2 = (int*)malloc(dimension * sizeof(int));
for (int i = 0; i < dimension; i++) {
temp1[i] = i;
temp2[i] = i;
}
out_array[0] = temp1;
out_array[1] = temp2;
printf("After Creating array inside arrayn");
for (int i = 0; i < 2; i++) {
for (int j = 0; j < dimension; j++) {
printf("%d ", out_array[i][j]);
}
printf("n");
}
return 0;
}

Output
After Creating array inside array
0 1 2 3 4
0 1 2 3 4
