(½ Mark for each correction)
OR
(1 mark for identifying the errors, without suggesting corrections)

(d) Find and write the output of the following C++ program code: (3)
Note: Assume all required header files are already being included in
the program.
void main( )
{
int Ar[ ] = { 6 , 3 , 8 , 10 , 4 , 6 , 7} ;
int *Ptr = Ar , I ;
cout<<++*Ptr++ << '@' ;
I = Ar[3] - Ar[2] ;
cout<<++*(Ptr+I)<<'@'<<"\n" ;
cout<<++I + *Ptr++ << '@' ;
cout<<*Ptr++ <<'@'<< '\n' ;
for( ; I >=0 ; I -=2)
cout<<Ar[I] << '@' ;
}

Ans 7@11@
6@8@
11@3@

(½ Mark for writing each correct value)
OR
(Only ½ Mark for writing all ‘@’ at proper places)
Note:
● Deduct only ½ Mark for not considering any or all correct placements of
@
● Deduct only ½ Mark for not considering any or all line break

(e) Find and write the output of the following C++ program code: (2)
typedef char STRING[80];
void MIXNOW(STRING S)
{
int Size=strlen(S);
for(int I=0;I<Size;I+=2)
{
char WS=S[I];
