Write the program to solve quadratic equations, but if the discriminant is negative, output

Firdavs [7]

Answer:

PROGRAM QuadraticEquation Solver

IMPLICIT NONE

REAL :: a, b, c ;

REA :: d ;

REAL :: root1, root2 ;

//read in the coefficients a, b and c

READ(*,*) a, b, c

WRITE(*,*) 'a = ', a

WRITE(*,*) 'b = ', b

WRITE(*,*) 'c = ', c

WRITE(*,*)

// computing the square root of discriminant d

d = b*b - 4.0*a*c

IF (d >= 0.0) THEN //checking if it is solvable?

d = SQRT(d)

root1 = (-b + d)/(2.0*a) // first root

root2 = (-b - d)/(2.0*a) // second root

WRITE(*,*) 'Roots are ', root1, ' and ', root2

ELSE //complex roots

WRITE(*,*) 'There is no real roots!'

WRITE(*,*) 'Discriminant = ', d

END IF

END PROGRAM QuadraticEquationSolver

Convert the following C program to C++.

ki77a [65]

Answer:

The program equivalent in C++ is:

#include <cstdio>

#include <cstdlib>

#define SIZE 5

using namespace std;

int main(int argc, char *argv[]) {

int numerator = 25;

int denominator = 10;

FILE * inPut = fopen(argv[1], "r");

FILE * outPut = fopen(argv[2], "w");

float result = (float)numerator/denominator;

fprintf(outPut,"Result is %.2f\n", result);

float arr[SIZE];

for(int i = 0; i < SIZE; i++) {

fscanf(inPut, "%f", &arr[i]);

fprintf(outPut, "%7.4f\n", arr[i]);

}

return 0;

}

CORRECT ANSWER GETS BRAINLIEST

I saw that all of them are correct. In 1905, the Wright Brothers flew their plane for 39.5 minutes. In 1969, Neil Armstrong landed on the moon. And the Wright brothers went throughout the U.S and Europe to demonstrate their plane. I hope this helps.

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binar

Mashcka [7]

Answer:

Following are the code to this question:

def binarynumber(num):#defining a method binarynumber that accepts a parameter num

x=""#defining a string variable x

if (num!=0):#defining if condition to check number not equal to 0

while (num>=1):#defining a loop that check value is grater then equal to one

if (num %2==0):#defining if condition to check num is even

x=x+"0" #add string value 0 in num variable

num=num/2 #divide the value by 2

else:#defining else block

x=x+"1"#add string value 1 in num variable

num=(num-1)/2#first subtract 1 into num variable then divide the value by 2

else:

x="0"#assign string value 0 in num variable

return "".join(reversed(x))#return value

num = int (input ("Enter any number: "))#defining num variable that input the integer value

print (binarynumber(num))#using print method to call method binarynumber with passing num parameter

Output:

Enter any number: 12

1100

Explanation:

In the above python code a method "binarynumber" is declared, in which the "num" variable passes as the parameter inside the method a string variable "x" is declared that stores all converted values.
Inside the method and if the block is declared that checks number value is not equal to 0 if this condition is false then it will add string value and reverse its value.
Or if the condition is true it defines a while loop that calculates the given number binary digits and returns its value.
At the last step, the num variable is declared that inputs the integer value from the user end and calls the method by using the print method.
