(Sub Code: 083 Paper Code 91/1 Delhi)
Ans iostream.h or iomanip.h or fstream.h
string.h
stdio.h
(½ Mark each for writing any two correct header files)
NOTE:
Ignore additional header file(s)
(c) Rewrite the following C++ code after removing any/all syntactical errors 2
with each correction underlined.
Note: Assume all required header files are already being included in the
program.
void main()
{
cout<<"Enter an integer";
cin>>N;
switch(N%2)
case 0 cout<<"Even"; Break;
case 1 cout<<"Odd" ; Break;
}
Ans void main()
{
int N; // Error 1
cout<<"Enter an integer";
cin>>N;
switch(N%2)
{ // Error 2 (i)
case 0: // Error 3 (i)
cout<<"Even"; break; // Error 4 (i)
case 1: // Error 3 (ii)
cout<<"Odd" ; break; // Error 4 (ii)
} // Error 2 (ii)
}
(½ Mark for correcting Error 1)
(½ Mark for correcting Error 2(i) and Error 2(ii))
(½ Mark for correcting Error 3(i) and Error 3(ii))
(½ Mark for correcting Error 4(i) and Error 4(ii))
OR
(1 Mark for identifying all the errors without corrections)
(d) Find and write the output of the following C++ program code: 2
Note: Assume all required header files are already included in the
program.
#define Big(A,B) (A>B)?A+1:B+2
void main()
