write a program to swap bits in a character and return the value
prototype of function
char fun (char a, charb flag c)
where fun returns a char, char a is a the value char b is
the bit to be changed and flag c is the bit value
for eg: x=fun(45,7,0)
since 45 is 0010 0101
and ow x should contain the value 65 (0110 0101)
18)struct base {int a,b;
base();
int virtual function1();
}
struct derv1:base{
int b,c,d;
derv1()
int virtual function1();
}
struct derv2 : base
{int a,e;
}
base::base()
{
a=2;b=3;
}
derv1::derv1(){
b=5;
c=10;d=11;}
base::function1()
{return(100);
}
derv1::function1()
{
return(200);
}
main()
base ba;
derv1 d1,d2;
printf("%d %d",d1.a,d1.b)
o/p is
a)a=2;b=3;
b)a=3; b=2;
c)a=5; b=10;
d)none
19) for the above program answer the following q's
main()
base da;
derv1 d1;
derv2 d2;
printf("%d %d %d",da.function1(),d1.function1(),d2.function1
());
o/p is
a)100,200,200;
b)200,100,200;
c)200,200,100;
d)none
20)struct {
int x;
int y;
}abc;
you can not access x by the following
1)abc-->x;
2)abc[0]-->x;
abc.x;
(abc)-->x;
a)1,2,3
b)2&3
c)1&2
d)1,3,4
2)#include<iostream.h>
main()
{
printf("Hello World");
}
the program prints Hello World without changing main() the
o/p should
be
intialisation
Hello World
Desruct
the changes should be
a)iostream operator<<(iostream os, char*s)
os<<'intialisation'<<(Hello World)<<Destruct
b) c) d)none of the above
What will be printed as the result of the operation below:
#include<..>
int x;
int modifyvalue()
{
return(x+=10);
}
int changevalue(int x)
{
return(x+=1);
}
void main()
{
int x=10;
x++;
changevalue(x);
x++;
modifyvalue();
printf("First output:%d\n",x);
x++;
changevalue(x);
printf("Second output:%d\n",x);
modifyvalue();
printf("Third output:%d\n",x);
}
hai iam working in sap sd module for one year and working
in lumax ind ltd in desp department but my problem is i
have done m.b.a in hr/marketing and working sap sd there is
any combination it. can you give right solution of my
problem. and what can i do?

whether a Directed Graph is connected or not?
3.Explain the process of converting a Tree to a Binary Tree.
3. When do you say that a digraph is acyclic
A)if and only if its first search does not have back arcs
B)a digraph is acyclic if and only if its first search does
not have back vertices
C)if and only if its first search does not have same
dfnumber
D)None of these

what are the difference between ANSI C and Let Us c and Turbo C
Write an interactive c program that will encode or decode a
line of text. To encode a line of text, proceed as follows:
Convert each character, including blank spaces, to its
ASCII equivalent.
Generate a positive random integer. Add this integer to the
ASCII equivalent of each character. The same random integer
will be used for the entire line of text.
Suppose that N1 represents the lowest permissible value in
the ASCII code, and N2 represents the highest permissible
value. If the number obtained in step 2 above exceeds N2,
then subtract the largest possible multiple of N2 from this
number, and add the remainder to N1. Hence the encoded
number will always fall between N1 and N2, and will
therefore always represent some ASCII character.
Display the characters that correspond to the encoded ASCII
values.
The procedure is reversed when decoding a line of text. Be
certain, however, that the same random number is used in
decoding as was used in encoding.
