Question

Using the new operator, allocate a two dimensional character array. Again the number of rows and columns

are going to be provided by the user as input. All of the rows are the same size. Take character strings as input from

the user and then print the strings. Finally de-allocate the array using the delete operator.

Answer 1

using namespace std;

#include <iostream>

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

Go()

{

char ** A;

int nRows,nColumns;

nRows = nColumns = 0;

while (nRows<1)

{

cout << " Please input # of rows :> ";

cin >> nRows;

}

while (nColumns<1)

{

cout << " Please input # of columns :> ";

cin >> nColumns;

}

A = (char**)malloc( nRows * sizeof(char*));

for (int rowLoop=0; rowLoop<nRows; rowLoop++)

{

A[rowLoop] = (char*)malloc(nColumns);

memset(A[rowLoop],0,nColumns);

}

for (int rowLoop=0; rowLoop<nRows; rowLoop++)

{

cin.clear(); fflush(stdin);

cout << " Please input string # " << (rowLoop+1) << ":>";

cin.getline(A[rowLoop],nColumns);

}

for (int rowLoop=0; rowLoop<nRows; rowLoop++)

{

cout << "string # " << (rowLoop+1) << " >" << A[rowLoop] << "< " << endl;

free(A[rowLoop]);

A[rowLoop]=NULL;

}

free(A);

}

int main() { Go(); }
