Today I am providing Various Important C++ Programs with coding.
AIM:
Write a C++ program to implement a stack
with its constructor and two member functions PUSH and POP.
CODING:
#include<iostream.h>
#include<conio.h>
#include<stdio.h>
#define size 4
class stact
{
int st;
int tos;
public:
stact();
~stact();
void push(int x);
pop ();
};
void stact::st()
{
tos=0;
cout<<"stact
incremented"<<endl;
}
void stact::~stact()
}
cout<<"stact is empty"<<endl;
return ;
}
void stact::push(int x)
{
if(tos==size)
{
cout<<"stack is
full"<<endl;
return;
}
stack[tos]=x;
tos++ ;
};
void st::pop()
{
if(t==0)
{
cout<<"stack is
empty"<<endl;
}---;
return stack[t];
}
void main()
{
st s1,s2,s3,s4;
s1.push(1);
s2.push(2);
s3.push(3);
s4.push(4);
cout<<"
"<<s4.pop();
cout<<"
"<<s3.pop();
cout<<"
"<<s2.pop();
cout<<" "<<s1.pop();
getch();
}

AIM:
Write a C++ program for an array of objects.
CODING:
#include<iostream.h>
#include<conio.h>
class Student
{
public:
char name[20];
int enrol;
char section[20];
void getdata()
{
cout<<"Enter the Name,Enrol & Section"<<endl;
cin>>name>>enrol>>section;
}
void showdata()
{
cout<<"Name of Student is : "<<name<<endl;
cout<<"Enrolment no. is : "<<enrol<<endl;
cout<<"Section is : "<<section<<endl;
}
};
main()
{
Student s[3];
for(int i=0;i<3;i++)
{
s[i].getdata();
}
for(i=0;i<3;i++)
{
s[i].showdata();
}
getch();
return 0;
}

AIM:
Write a C++ program for Friend function.
CODING:
#include<iostream.h>
#include<conio.h>
class demo
{
private:
int a,b;
public:
void setvalue()
{
a=10;
b=15;
}
friend int add(demo d);
};
int add(demo d)
{
return int(d.a+d.b);
}
main()
{
clrscr();
demo d1;
d1.setvalue();
cout<<"addition
is="<<add(d1);
getch();
return 0;
}
