Write a program to check whether the given number is even or odd (using ? : ternary operator )

#include<iostream>
using namespace std;

int main()
{
 int a;
 cout<<"Enter the Number : ";
 cin>>a;
 (a%2==0)?cout<<"Number is even":cout<<"Number is odd";

 
 return 0;
}

Write a program to check whether the given number is positive or negative (using ? : ternary operator )

#include<iostream>
using namespace std;

int main()
{
 int a;
 cout<<"Enter any non-zero Number : ";
 cin>>a;
 (a>0)?cout<<"Number is positive":cout<<"Number is negative";
 
 
 return 0;
}

Write a program to calculate area of circle.

#include<iostream>
using namespace std;

int main()
{
 float r,area;
 cout<< "\nEnter radius of circle : ";

 cin>>r;
 area = 3.14*r*r;

 cout<<"Area of circle : "<<area;
 
 return 0;
}

Write a program to swap the values of two variables.

#include<iostream>
using namespace std;

int main()
{
 int a,b,temp;
 cout<<"\nEnter two numbers : ";
 cin>>a>>b;
 temp=a; 
 a=b;
 b=temp;
 cout<<"\nAfter swapping numbers are : ";
 cout<<a<<" "<<b;

 return 0;
}

Write a program which accepts a character and display its ASCII value.

#include<iostream>
using namespace std;

int main()
{
 char ch;
 cout<<"\nEnter any character : ";
 cin>>ch;
 cout<<"ASCII equivalent is : "<<static_cast<int>(ch);
 
 
 return 0;
}

Write a program which accept principle, rate and time from user and print the simple interest.

#include<iostream>
using namespace std;

int main()
{
 int p,r,t,i;
 cout<<"Enter Principle : ";
 cin>>p;
 cout<<"Enter Rate : ";
 cin>>r;
 cout<<"Enter Time : ";
 cin>>t;
 i=(p*r*t)/100;
 cout<<"Simple interest is : "<<i;

 
 return 0;
}
