Question

You are provided with the following program poem.cpp. All is good, and the memory is allocated dynamically, but it crashes your computer, because it runs out of memory really quickly:

#include
using namespace std;

string * createAPoemDynamically() {
string *p = new string;
*p = "Roses are red, violets are blue";
return p;
}

int main() {
while(true) {
string *p;
p = createAPoemDynamically();

// assume that the poem p is not needed at this point

}
}
Fix this program poem.cpp. It should still keep creating poems, but all dynamically allocated memory should get deleted when it is not needed.

Answer 1

Answer:

See explaination

Explanation:

#include <iostream>

using namespace std;

string * createAPoemDynamically()

{

string *p = new string;

*p = "Roses are red, violets are blue";

return p;

}

int main() {

while(true) {

string *p;

p = createAPoemDynamically();

if (!p)

{

cout << "Memory allocation failed\n";

}

cout<<*p<<"\n";

// assume that the poem p is not needed at this point

//delete allocated memory

delete p;

}

}
