CBSE CLASS XII

Ans.
#include <iostream.h>
#include <stdio.h>
class MyStudent
{ int StudentId;
char Name[20];
public:
MyStudent( ) { }
void Register( )
{
cin>>StudentId;
gets(Name);
}
void Display( )
{ cout<<StudentId<<":"<<Name<<endl;
}
};
void main( )
{MyStudent MS;
MS.Register( );
MS.Display( );
}

1.e. Find the output of the following program:

#include<iostream.h>
#include<ctype.h>
void Secret(char Msg[ ], int N);
void main( )
{ char SMS[ ]=”rEPorTmE”;
Secret(SMS,2);
cout<<SMS<<endl;
}
void Secret(char Msg[ ], int N)
{ for(int C=0;Msg[C]!=’\0’;C++)
if(C%2= =0)
Msg[C]=Msg[C]+N;
else if(isupper(Msg[C]))
Msg[C]=tolower(Msg[C]);
else
Msg[C]=Msg[C]-N;
}
