Answer:
machine language uses binary code and assembly language uses mnemonic codes to write a program.
Explanation:
In a nutshell, machine language uses binary code, which is almost impossible for humans to decipher, whereas assembly language uses mnemonic codes to write a program. Mnemonic codes make it simpler for humans to understand or remember something, and so make the language a bit easier for humans to use than machine code.

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;
}
}
