Biggest of 3 Numbers Using Ternary Operator: C++

Video tutorial to find the biggest of the three integer numbers in C++, using if-else control statements and Ternary Operator.

Before watching this video, please make sure to watch and understand this short video: Find Biggest of 3 Numbers: C++

Full Source Code

#include<iostream .h>
#include<conio .h>
 
void main()
{
int a, b, c;
clrscr();
 
cout< <"Enter 3 no's\n";
cin>>a>>b>>c;
 
int big =  ( a>b && a>c )?a:(b>c?b:c);
/*
if( a > b && a > c )
  big = a;
else if( b > c )
  big = b;
else
  big = c;
*/cout< <"\nAmong "<<a<<" , "<<b<<" , "<<c<<" Biggest is "<<big;
getch();
}

In this program we take 3 integer values from the user and using ternary operator decide the biggest of 3 numbers.

int big =  ( a>b && a>c )?a:(b>c?b:c);

if ( a > b && a > c ) is true, then value of a will be stored in variable big; else ( b > c ? b : c ) will be evaluated. Here, if value of b is greater than c, value of b will be stored in variable big else value of c will be stored in the variable big.

Find Biggest of 3 Numbers: C++

Video tutorial to find the biggest of the three integer numbers in C++, using if-else control statements.

Full Source Code

#include<iostream .h>
#include<conio .h>
 
void main()
{
int a, b, c;
clrscr();
 
cout< <"Enter 3 no\n";
cin>>a>>b>>c;
 
int big;
 
if( a > b )
 big = a;
else
{
 if( b > c )
  big = b;
 else
  big = c;
}
cout< <"\nBiggest is: "<<big;
getch();
}

In this program we get three integer variables from the user.
If value of variable a is bigger, then we store it inside the variable big; else we compare b with c. Now will store the biggest number inside the variable big.

Biggest of Two Numbers Using Ternary Operator: C++

Video tutorial to find the biggest of the two integer numbers in C++, using Ternary Operator.

To find biggest of Two numbers using if-else control structure: Find Biggest of 2 Numbers: C++

Full Source Code

#include < iostream .h >
#include < conio .h >
 
void main()
{
 int a, b;
 clrscr();
 
 cout< <"Enter 2 numbers\n";
 cin>>a>>b;
 
 int big;
 
 big = a > b ? a : b;
 
/*
 if( a > b )
  big = a;
 else
  big = b;
*/ 
 cout< <"\nBig is: "<<big;
 
 getch();
}

In this program we take 2 integer values from the user and using ternary operator decide the biggest of 2 numbers.

 big = a > b ? a : b;

if ( a > b ) is true, then value of a will be stored in variable big; else value of b will be stored in big.

Find Biggest of 2 Numbers: C++

Video tutorial to find the biggest of the two integer numbers in C++, using if-else control statements.

Full Source Code

 
#include < iostream .h >
#include < conio .h  ">


void main()
{
int a, b;
clrscr();

cout< <"Enter 2 numbers\n";
cin>>a>>b;

int big;

if( a > b )
 big = a;
else
 big = b;

cout< < endl << "among " << a << "="" and="" " << b<<"="" biggest= "" is="" " << big;

In this program we get two integer variables from the user.
If value of variable a is bigger, then we store it inside the variable big; else we store the value of variable b inside variable big.
Finally display the value of variable big which contains the biggest number amongst the two values entered by the user.

Addition of 2 Numbers: C++

This video tutorial illustrates a simple program of adding two integer numbers.

Full Source Code

#include<iostream .h>
#include<conio .h>
 
void main()
{
 
 int a, b;
 clrscr();
 
 cout< <"Enter two no\n";
 cin>>a>>b;
 
 int sum = a + b;
 
 cout< <endl<<"Sum is: "<<sum;
 
 getch();
 
}

We can declare variables anywhere in a cpp program.
