Hey guys out there.......I m starting this thread for all the twelthies who will be writing there CS exams on 31st.......

let us practise some questions........

heres first one.........

FIND THE OUTPUT....

#include<iostream.h>
#include<string.h>
#include<ctype.h>
void Convert(char Str[], int Len)
{
    for (int Count=0; Count<Len; Count++)
    {
        if (isupper(Str[Count]))
            Str[Count] = tolower(Str[Count]);
        else if (islower(Str[Count]))
            Str[Count] = toupper(Str[Count]);
        else if (isdigit(Str[Count]))
            Str[Count] = Str[Count] + 1;
        else Str[Count] = '*';
    }
}
void main()
{
    char Text[] = "CBSE Exam 2008";
    int Size=strlen(Text);
    Convert(Text, Size);
    cout<<Text<<endl;
    for (int C = 0, R = Size - 1; C <= Size/2; C++, R--)
    {
        char Temp = Text[C];
        Text[C] = Text[R];
        Text[R] = Temp;
    }
    cout << Text << endl;
}

My best wishes to everyone..........

BEST OF LUCK..........

give the output...........

#include<iostream.h>
void strfn(char * *s)
{
    char *n = "INDIA";
    *s = n;
}
void main()
{
    char *str = "Bharat";
    strfn(&str);
    for (int x = 0; str[x]>0;x++)
    {
        for(int y = 0; y <= x; y++)
            cout << str[y];
        cout << endl;
    }
}

Output is:
I
IN
IND
INDI
INDIA

Here str[x]>0 means that until it is not null. Ascii value of null is 0. so its checking whether the ascii value of character being checked is greater than 0

BRILLIANT SNEHA........

heres another one.......

#include <iostream.h>
class integer
{
   int m, n;
   public :
       integer(int, int);   // constructor declared
       void display(void)
       {
           cout << " m = " << m << "\n";
           cout << " n = " << n << "\n";
       }
};
integer::integer(int x, int y)    // constructor defined
{
   m = x;
   n = y;
}
main()
{
   integer int1(0, 100);   // implicit call
   integer int2 = integer(25, 75);   // explicit calls
   cout << "\nOBJECT1" << "\n";
   int1.display( );
   cout << "\nOBJECT2" << "\n";
   int2.display( );
}
