Question 1)Read the data from one file and remove all the
duplicated words and generate an output file containg only
using words.Program should also print number of occurance
of each words on standard output.(Program must be use STL
and iostream object).
Question 2)Write a program to convert the lower case
contents of file to upper case using STL.
Question 3)What is the output of this problem.
int i=12;
int &r =i;
r+r/4;
int +p =&r;
int *p = &r;
P+=r;
return 1;
Answer :a)12 b)17 c) 30 d)24 E)15
Question 4)

void main()
{
char srcstr[30],desstr[30];
int i,len;
clrscr();
cout<<"\nenter the string\n";
cin>>srcstr;
len=strlen(srcstr);
for(i=0;srcstr[i]!='\0';i++)
{
desstr[--len]=srcstr[i];
}
desstr[i]='\0';
cout<<"\nreversed string is\n";
for(i=0;desstr[i]!='\0';i++)
{
cout< }
getch();
}

if(!in)
{
cout<<"Cannot open input.txt";
exit(0);
}
while(in)
{
in.get(ch);
lst.push_back(ch);
}
p=lst.begin();
while(p!=lst.end())
{
*p=toupper(*p);
p++;
}
p=lst.begin();
while(p!=lst.end())

Answer / manoj kumar kar

Question 3)What is the output of this problem.
int i=12;
int &r =i;
r+r/4;
int *p = &r;
P+=r;
return i;
Answer :a)12 b)17 c) 30 d)24 E)15
// Answer will be 12.
r is a reference to i so both r and i will be 12 at first.
r+r/4 is meaningless as there is no assinment.
p is a pointer so increamenting p will not manipulate the
value stored at p(The value of r will not be changed if we
increase p if we want to increase the value of r then we
have to do (*p)+=r).
Qustion 4:
//It will output the reverse string.
Question 5:
Not clear with the question.
Question 6:
//Space is always reserved for base class variables in
derived class objects.So if sizeof(int)=4 and sizeof(char)=1
then answer will be
5 Bytes for Class A and 10 Bytes for Class B.
