Squre roots of a quadratic equation programme in python

#  ax2 + bx + c = 0. Recall that such an equation has two
#solutions for the value of x, and these are given by the formula
#          x = -b +- sqrt(b2 – 4ac) / 2a


import math


a=input("Enter the value of a")
b=input("Enter the value of b")
c=input("Enter the value of c")


d=(b*b-4*a*c)
d=math.sqrt(d) #predefine function in python


root1=(-b+d)/2*a
root2=(-b-d)/2*a


print 'first root is',root1
print '\nsecond root is',root2

Swap two variable values using C++ programming language without using third variable or temporary variable

/*Without using any third varible*/

#include<iostream.h>

 Using namespace std

    void main()

      {

             int a,b ;

             a=1 ;

             b=2 ;

    
          SwapInC++(a , b) ;  //swap function call

     
          Cout<<"values after swap a= "<< a <<endl ;

    
          Cout<<"values after swap b= "<< b <<endl ;

       }  //End of main

    void SwapInC++(int x,int y)  //definition of Swap functon

    {

          y= x-y+(x=y);

     }

Common Programming Error:-
C++ compiler read from left to right to do not Confound with swap logic.

Good Programming Practice:-
always use equation like here i used instead using another temporary storage.

Swap two variable value using C programming without using third variable or temporary variable

/* Without using any third varible*/

#include<stdio.h>

  void SwapInCv(int x , int y) ;  //function reference

  void main()

     {

             int a,b ;
             a=1 ;

             b=2 ;

         
           SwapInC(a,b) ;  //swap function call

  
             printf("values after swaping a=%d & b=%d ", a , b) ;

     }  //End of main

   void SwapInC(int x,int y)  //definition of Swap functon

    {

       y= x-y+(x=y);

    }

Common Programming Error:-
C compiler read from left to right to do not confound with swap or switch logic.

Good Programming Practice:-
always use equation like  i used instead using another temporary storage.

How to generate Milli second digital delay using C programming

/* Milli  second digital delay (Input value assign by the user)*/

void DelayMS(int delayInMs)   //value of delayInMs=1,2,3,.......
   {
  usigned long i,j;
for(i=0;i<delayInMs;i++)

for(j=0;j<6024;j++);

    }  //End of function

void main()
{
  DelayMs(500);//generate delay of 500 ms
}

Common Programming Errors:-
Sometime programmer started with main and give the definition of function after that. its shows error to avoid that you can write only function name before main and define after main.

Good Programming Practice:-
Use uppercase letter for function name and you can use underscore( _ ) sign also.

A digital delay function in C Programming

/*Generate a long  digital delay*/

{
          for (j = 1; j < 5500; j++) ; //6000
