Program Of Call By Value Using C

#include<stdio.h>

#include<conio.h>

int sum(int a,int b);

main()

{

int x,y,z;

clrscr();

printf("Enter First NUmber=");

scanf("%d",&x);

printf("Enter Second NUmber=");

scanf("%d",&y);

z=sum(x,y);

printf("\n Answer=%d",z);

getch();

}

int sum(int a,int b)

{

int c;

c=a+b;

return c;

}

Program Of Call By Address Using c

#include<stdio.h>

#include<conio.h>

int sum(int *a,int *b);

main()

{

int x,y,z;

clrscr();

printf("ENter First NUmber=");

scanf("%d",&x);

printf("ENter Second NUmber=");

scanf("%d",&y);

z=sum(&x,&y);

printf("\n Answer=%d",z);

getch();

}

int sum(int *a,int *b)

{

int c;

c= *a + *b;

return c;

}

Program Of Call By Refrence in c

#include<stdio.h>

#include<conio.h>

int sum(int &a,int &b);

main()

{

int x,y,z;

clrscr();

printf("ENter First NUmber=");

scanf("%d",&x);

printf("ENter Second NUmber=");

scanf("%d",&y);

z=sum(x,y);

printf("\n Answer=%d",z);

getch();

}

int sum(int &a,int &b)

{

int c;

c= a + b;

return c;

}

Program Of Template Class In C++

#include<iostream.h> 

#include<conio.h>
template<class T> 

class add{ private: T a,b;
public:    
   void getdata(T x,T y) 
{  
 a=x; 
 b=y; 
}
void display() 
{
cout<<"a="<<a; 
cout<<"b="<<b;
}
};
void main()
{ 
add <int> a1;
clrscr(); 
a1.getdata(4,6);
a1.display();
add <float> a2;
a2.getdata(3.4,4.5);
a2.display();
getch();
}

Program To Remove The Problems of Function Overloading

#include<iostream.h>

#include<conio.h>

template<class T>

class add

{

private:

T a;

public:

       void getdatab(T x)

{

 a=x;

}

void displayb()

{

cout<<"a="<<a;

}

};

template<class T>

class sub : public add <T>

{

private:

T b;

public:

       void getdatad(T y)

{

 b=y;

}

void displayd()

{

cout<<"\n b="<<b;

}

};

void main()

{

sub <int> a1;

clrscr();

a1.getdatab(4);

a1.displayb();

a1.getdatad(6);

a1.displayd();

getch();

}
