C++(Absolute value)

Find the absolute value of a number entered by the user. 

int main()

{

      int a;

      cout<<"Enter any number:";

      cin>>a;

      if(a>0)

            cout<<"The absolute value of number is:"<<a;

      else

            cout<<"The absolute value of number is:"<<-(a);

      getch();

      return 0;

}

C++ basic program

Any integer is input by the user. Write a program to find out whether it is an odd number or even number. 

 int main()

{

      int a;

      cout<<"Enter any number : ";

      cin>>a;

      if(a%2==0)

            cout<<"The number is even";

      else

            cout<<"The number is odd";

      getch();

      return 0;

}

C++(Year,Months and Days)

Write a program which accepts days as integer and display total number of years, months and days in it.
for example :  If user input as 856 days the output should be 2 years 4 months 6 days. 

#include<iostream.h>

#include<conio.h>

int main()

{

      int days,y,m,d;

      cout<<"Enter no. of days : ";

      cin>>days;

      y=days/365;

      days=days%365;

      m=days/30;

      d=days%30;

      cout<<"Years : "<<y<<"\nMonths : "<<m<<"\nDays : "<<d;

      getch();

      return 0;

}

C++(Display Next Character)

Write a program which accepts a character and display its next character. 

Sol:  #include<iostream.h>

#include<conio.h>

int main()

{

      char ch;

      cout<< "\nEnter any character : ";

      cin>>ch;

      ch++;

      cout<<"Next character is : "<<ch;

      getch();

      return 0;

}

C++(Display No. Of Notes)

Write a program which accepts amount as integer and display total number of Notes of Rs. 500, 100, 50, 20, 10, 5 and 1.
For example, when user enter a number, 575,
the results would be like this...
500: 1
100: 0
50: 1
20: 1
10: 0
5: 1
1: 0 

Sol:

#include<iostream.h>

#include<conio.h>

int main()

{

      int amt,R500,R100,R50,R20,R10,R5,R1;

      cout<<"Enter amount : ";

      cin>>amt;

      R500=amt/500;

      amt=amt%500;

      R100=amt/100;

      amt=amt%100;

      R50=amt/50;

      amt=amt%50;

      R20=amt/20;

      amt=amt%20;

      R10=amt/10;

      amt=amt%10;

      R5=amt/5;

      amt=amt%5;

      R1=amt;

      cout<<"Rs.500 : "<<R500<<"\nRs.100 : "<<R100<<"\nRs. 50 : "<<R50<<

            "\nRs. 20 : "<<R20<<"\nRs. 10 : "<<R10<<"\nRs.  5 : "<<R5<<"\nRe.  1 : "<<R1;

      getch();

      return 0;

}

C++(Display Largest Number)

C++(Check Even or Odd)

10

-Write a program to check whether the given number is even or odd (using ? : ternary operator )  #include<iostream.h> #include<conio.h>   int main() {       int a;       cout<<"Enter the Number : ";       cin>>a;       (a%2==0)?cout<<"Number is even":cout<<"Number is odd";         getch();       return 0; }
