Step 1. Start
Step 2. Read the coefficients of the equation, a, b and c from the user.
Step 3. Calculate discriminant = (b * b) – (4 * a * c)
Step 4. If discriminant > 0:
4.1: Calculate root1 = ( -b + sqrt(discriminant)) / (2 * a)
4.2: Calculate root2 = ( -b - sqrt(discriminant)) / (2 * a)
4.3: Display “Roots are real and different”
4.4: Display root1 and root2
Step 5: Else if discriminant = 0:
5.1: Calculate root1 = -b / (2 *a)
5.2: root2 = root1
5.3: Display “Root are real and equal”
5.4: Display root1 and root2
Step 6. Else:
6.1: Calculate real = -b / (2 * a)
6.2:Calculate imaginary = sqrt(-discriminant) / (2 * a)
6.3: Display “Roots are imaginary”
6.4: Display real, “±” , imaginary, “i”
Step 7. Stop

Algorithm to find whether a Number is Prime Number or Not



What is a Prime Number?
A number that's only divisible by 1 and itself is named a Prime Number. For Example, 3, 5, 7, 11 are Prime Numbers.
Note: 2 is the only even prime number.

Flowchart for Prime Number:

Algorithm
Algorithm for Prime Number:
Step 1: Start
Step 2: Initialize variables num,flag=1, j=2
Step 3: Read num from user
Step 4: If num<=1 // Any number less than 1 is not a prime number
Display "num is not a prime number"
Goto step 7
Step 5: Repeat the steps until j<[(n/2)+1]
5.1 If remainder of number divide j equals to 0,
Set flag=0
Goto step 6
5.2 j=j+1
Step 6: If flag==0,
Display num+" is not prime number"
Else
Display num+" n is prime number"
Step 7: Stop

#include <iostream>
using namespace std;


int day = 4;
switch (day) {
case 1:
cout << "Monday";
break;
case 2:
cout << "Tuesday";

case 3:
cout << "Wednesday";

case 4:
cout << "Thursday";
break;
case 5:
cout << "Friday";
break;
case 6:
cout << "Saturday";
break;
case 7:
cout << "Sunday";
break;
}



// Outputs "Thursday" (day 4)

How to find the factorial of any number using for loop.? That accept a num from user

#include<iostream>
using namespace std;
int main()
{
int no,f=1;
cout<<"Enter any number\n";
cin>>no;
for(int i=1;i<=no;i++)
{
f=f*i;
}
cout<<"Factorial="<<f;

CALL BY VALUE


#include<iostream>
using namespace std;
void add(int y,int z)
{
int x;
x=y+z;
cout<<"Add="<<x;
}
int main()
{
add(10,20);
}


//the output is ....30

CALL BY REFERENCE

#include<iostream>
using namespace std;
void add(int *y,int *z)
{
int x;
x=*y+*z;
cout<<"Add="<<x;
}
int main()
{
int a=20,b=50;
add(&a,&b);
}


The output is. ...70
