Ques. 1  a) What do you mean by free store with reference to memory allocation in c++?

b) How #define different from const explain ?

c) Which C++ header file(s) will be essentially required to be included to run / execute the following C++ code?

{

int Mno;

Register();

delete.Display();

}

e) Give the output of the following program segment (Assuming all required header files are included in the program):

# include<ctype.h>

void change (char* state, int &s)

{ int b = s;

for (int x = 0; s>=0; x++, s−−)

if ((x+s)%2)

*(state+x) = toupper(*(state+b-x));

}
