1.Write a program which illustrates the use of scope resolution operator.
Shared By : Master Pankaj Sharma (JVIMS College Jamnagar )
#include<iostream.h>
#include<conio.h>
class example
{
public :
static int a;
};
int example::a=10;
void main()
{
clrscr();
int a=20;
{
cout<<"\nWITHOUT SCOPE RESOLUTION(LOCAL VALUE):"<<a<<endl;
cout<<"\nUSING SCOPE RESOLUTION:"<<example::a<<endl;
int a=100;
cout<<"\n=========================\nAFTER CHANGING LOCAL VALUE\n===========================\n";
cout<<"\nWITHOUT SCOPE RESOLUTION(LOCAL VALUE)"<<a<<endl;
cout<<"\nUSING SCOPE RESOLUTION"<<example::a<<endl;
}
getch();
}
2.Define a class to represent a bank account. Include the following members :
DATA MEMBERS
Name of depositor, Account Number, Type of Account
MEMBER FUNCTIONS
To assign initial values
To Deposit the amount
To withdraw an amount after checking the Balance amount in account
To display name and balance
#include<iostream.h>
#include<conio.h>
#include<string.h>
#include<stdlib.h>
class bank
{
char name[20];
char type;
int acn;
static int num;
long int bal;
public:
bank()
{
}
bank(char tname[],int tno,char ttype)
{
strcpy(name,tname);
num=tno;
type=ttype;
}
void display()
{
cout<<"\n\nA/C NUMBER"<<acn;
cout<<"\n\nNAME="<<name<<endl;
cout<<"\n\nTYPE OF ACCOUNT="<<type<<endl;
cout<<"\n\nBALANCE="<<bal<<endl;
getch();
}
void getdata()
{
num++;
acn=num;
cout<<"ACCOUNT NUMBER:"<<acn;
cout<<"\n\nENTER NAME:";
cin>>name;
type1:
cout<<"\nA/C TYPE (S:SAVING C:CURRENT):";
cin>>type;
if(!(type=='S' || type=='C' || type=='s' || type=='c'))
goto type1;
bal1:
cout<<"\nENTER BALANCE(minmum 1000):";
cin>>bal;
if(bal<1000)
goto bal1;
cout<<"\nCUSTOMER REGISTRATION SUCCESSFULLY\n\n";
getch();
}
void deposit()
{
long int amt;
amt2:
cout<<"\n ENTER AMOUNT TO DEPOSIT:";
cin>>amt;
if(amt<1)
{
cout<<"\n\tENTER PROPER AMOUNT";
goto amt2;
}
bal=bal+amt;
cout<<"\n\nAMOUNT DEPOSIT SUCCESSFULLY.\n";
getch();
}
void withdrow()
{
long int amt;
cout<<"\nENTER AMOUT TO WITHDROW:";
cin>>amt;
int temp=bal-amt;
if(temp<1000 || amt<0)
cout<<"\nSORRY!! , YOU DON'T HAVE SUFFICIENT AMOUT\nOR\nENTER PROPER INFO.";
else
{
bal=bal-amt;
cout<<"\nAMOUT WITHDOW SUCCESSFULLY.\n";
}
getch();
}
int chkacno(int acno)
{
if(acno==acn)
return 0;
else
return 1;
}
};
int bank::num=1000;
void main()
{
bank cust1[10];
int ch,count=-1,acno=0;
char exitchoice='n';
clrscr();
do
{
cout<<"\n\t============================================";
cout<<"\n\n\t\tWELCOME TO BANKING SYSTEM\n\n";
cout<<"\t============================================\n\n\n";
cout<<"\t\t1.REGISTRATION\n\n\t\t2.DEPOSIT\n\n\t\t3.WITHDROW\n\n\t\t4.DISPLAY\n\n\t\t5.EXIT\n";
cout<<"\n\n\t\tENTER CHOICE:";
cin>>ch;
switch(ch)
{
case 1:
clrscr();
cout<<"\n\tREGISTRATION FORM\n\n";
cout<<"\t=====================\n\n";
count++;
cust1[count].getdata();
break;
case 2:
clrscr();
cout<<"\n\tDEPOSIT FORM\n\n";
cout<<"\t=====================\n\n";
cout<<"\n\tENTER ACCOUNT NO:";
cin>>acno;
for(int i=0;i<=count;i++)
{
if(cust1[i].chkacno(acno)==0)
{
cust1[i].deposit();
goto end2;
}
}
cout<<"\n\tSORRY!!! ACCOUNT NO AVAILABLE...";
end2:
getch();
break;
case 3:
clrscr();
cout<<"\n\tWITHDRAW FORM\n\n";
cout<<"\t=====================\n\n";
cout<<"ENTER ACCOUNT NO:";
cin>>acno;
for(i=0;i<=count;i++)
{
if(cust1[i].chkacno(acno)==0)
{
cust1[i].withdrow();
goto end1;
}
}
cout<<"\n\tSORRY!!! ACCOUNT NO AVAILABLE...";
end1:
getch();
break;
case 4:
clrscr();
cout<<"\n\tCUSTOMER INFORMATION FORM\n\n";
cout<<"\t===========================\n\n";
cout<<"ENTER ACCOUNT NO:";
cin>>acno;
for(i=0;i<=count;i++)
{
if(cust1[i].chkacno(acno)==0)
{
cust1[i].display();
}
}
cout<<"SORRY!!! ACCOUNT NO AVAILABLE...";
break;
case 5:
exitchoice='y';
default:
cout<<"ENTER PROPER CHOICE!!!";
}
clrscr();
}
while(exitchoice=='n');
}
3.Demonstrate the use of static variables in a class by using it to count the number of
objects created in the program
#include<iostream.h>
#include<iostream.h>
#include<conio.h>
class myclass
{
int a;
public:
static int count;
myclass()
{
count++;
}
};
int myclass::count=0;
int main()
{
myclass obj1;
clrscr();
cout<<endl<<myclass::count;
getch();
return 0;
}
4.Write a program that calculates the value of m raised to power n for both int and double
data types. (Use the concept of function overloading).
#include<iostream.h>
#include<conio.h>
int raise(int , int);
double raise(double,int);
void main()
{
int x,n;
double dx,dn;
clrscr();
cout<<"Enter Number x";
cin>>x;
cout<<"Enter Value of n";
cin>>n;
cout<<"ANS INT:"<<raise(x,n);
cout<<"\nEnter Number x";
cin>>dx;
cout<<"Enter Value of n";
cin>>n;
cout<<"ANS INT:"<<raise(dx,n);
getch();
}
int raise(int x,int n)
{
int ans=x;
for(int i=1;i<n;i++)
{
ans*=x;
}
return ans;
}
double raise(double x,int n)
{
double ans=x;
for(int i=1;i<n;i++)
{
ans*=x;
}
return ans;
}
5.Write a class to represent a vector. Include member functions to perform the following
1. To create the vector
2. To modify the value of a given element
3. To multiply by a scalar value
4. To display the vector in the form(10,20,30...)
Programs: 1-5 6-10 11-15 16-20 21-30 31-35 35-38
#include<iostream.h>
#include<conio.h>
class vector
{
public:
int n;
void createVector();
void modifyVector();
void multiplyVector(int);
void displayVector();
};
void vector :: createVector()
{
cout << "Enter Value:";
cin>>n;
}
void vector :: displayVector()
{
cout << n <<",";
}
void vector::modifyVector()
{
int newval;
cout <<"Enter New Value:";
cin>>newval;
n=newval;
}
void vector:: multiplyVector(int s)
{
n=s*n;
}
int main()
{
vector v[10];
int ch,exit=0;
do
{
clrscr();
cout <<"Vector Program\n\n";
cout <<"==================\n";
cout <<" Choices:\n";
cout <<"1. Create Vector\n";
cout <<"2. Modify Vector\n";
cout <<"3. Scalar Multiply Vector\n";
cout <<"4. Display Vector\n";
cout <<"5. Exit Vector\n";
cout <<"Enter Your Choice:";
cin>>ch;
switch(ch)
{
case 1: //create
for(int i=0;i<10;i++)
{
v[i].createVector();
}
break;
case 2: //modify
int index;
cout <<"Enter Position to Modify:";
cin>>index;
v[index].modifyVector();
break;
case 3: //scalar multiply
int s;
cout <<"Enter Scalar Value:";
cin>>s;
for(i=0;i<10;i++)
{
v[i].multiplyVector(s);
}
break;
case 4: //Display
for(i=0;i<10;i++)
{
v[i].displayVector();
}
break;
case 5:
exit=1;
break;
}
getch();
} while(exit!=1);
}
