Converting 2 dimemsional array to 3 dimensional array and vice versa in c++

### Introduction

The following program converts two dimensional array to three dimensional array using TwoDimToThree() and converts three dimensional array to two dimensional array ussing ThreeDimToTwo() .

Code: Cpp

`#include<iostream>using namespace std;void TwoDimToThree();void ThreeDimToTwo();main(){    cout<<"If u want to convert 2d array to 3d array enter 1 "<<endl;    cout<<endl<<"If u want to convert 3d array to 2d array enter 2 "<<endl;    int n;    cin>>n;    if(n==1)        TwoDimToThree();    else        ThreeDimToTwo();}void TwoDimToThree(){    cout<<"Enter the no. of rows and column for 2d array "<<endl;    int Row,Col;    cin>>Row>>Col;    cout<<"Enter "<<Row*Col<<" elements for the 2d array"<<endl;    int i,j,k,a[Row][Col],b[Row][Row][Col];    for(i=0;i<Row;i++)        for(j=0;j<Col;j++)            cin>>a[i][j];    cout<<"The elements of 2d array are "<<endl;    for(i=0;i<Row;i++)        for(j=0;j<Col;j++)            cout<<"a["<<i<<"]["<<j<<"] = "<<a[i][j]<<endl;    cout<<"The elements of 3d array are "<<endl;    for(i=0;i<Row;i++)    {        for(j=0;j<Row;j++)            for(j=0;j<Row;j++)            {                for(k=0;k<Col;k++)                {                    b[i][j][k]=a[j][k];                    cout<<"b["<<i<<"]["<<j<<"]["<<k<<"] = "<<b[i][j][k]<<endl;                }            }    }}void ThreeDimToTwo(){    cout<<"Enter the no. of rows , column , length of 3d array "<<endl;    int Row,Col,Len;    cin>>Row>>Col>>Len;    cout<<"Enter "<<(Row*Col)*Len<<" elements"<<endl;    int a[Row][Col][Len],b[Row][Row*Col];    int i,j,k;    for(i=0;i<Row;i++)        for(j=0;j<Col;j++)            for(k=0;k<Len;k++)                cin>>a[i][j][k];    int l=0,m=0,p;    cout<<"Elements of the three dimensional array are "<<endl;    for(i=0;i<Row;i++)    {        for(j=0;j<Col;j++)        {            for(k=0;k<Len;k++)            {                b[l][m]=a[i][j][k];                cout<<"a["<<i<<"]["<<j<<"]["<<k<<"] = "<<a[i][j][k]<<endl;                m++;                p=m;            }        }        m=0,l++;    }    cout<<endl<<"Elements of two dimensional array are "<<endl;    for(i=0;i<l;i++)    {        for(j=0;j<p;j++)            cout<<"b["<<i<<"]["<<j<<"] = "<<b[i][j]<<endl;    }}`
