Question

c++

Please code a string object to be stored in 3 different memory and to hold "CSC340" as value. The please explain the main difference between the 3 methods.

Please help! Thank you!

Answer 1

We can create string object in 3 different memory and to hold "CSC340" as value.

i) string s1 {"CSC340"};

ii) string* s2 = new string {“CSC340”};

iii) static string s3 {“CSC340”};

When we create string object using the following statement

string s1 {"CSC340"};

then string object s1 created on the stack region from memory.

When we create string object using the following statement (using new operator)

string* s2 = new string {“CSC340”};

then string object s2 created on the heap region from memory.

And when we create string object using the following statement (using static keyword)

static string s3 {“CSC340”};

then static memory allocation take place
