In Python, if var1 = "Happy" and var2= "Birthday" and var3 = (var 1+var2) *2, then var3 stores the string
nordsb [41]

Answer:

The answer is "Option A".

Explanation:

The program to the given question can be given as:

program:

var1 = "Happy" #defining variable var1

var2= "Birthday" #defining variable var2

var3 = (var1+var2) *2 #defining variable var3 and calculate value

print (var3) #print value.

Output:

HappyBirthdayHappyBirthday

In the above python program, three variable is defined, that is var1, var2, and var3, in which variable var1 and var2 we assign a value, that is "Happy" and "Birthday".

In variable var3 we add the value of var1 and var2 variable and multiply by 2. It will print the variable value two times. and other options are not correct that can be defined as:

  • In option B and C, Both variable var1 and var2 print there values two times but in option B var1 value print two time and var2 value print one time only and option C var1 variable value is print only one time and var2 variable value is print two times that's why it is not correct.
  • In option C, Both variable var1 and var2 print there values two times that's why it is not correct.

Brums [2.3K]

Answer:

#include <iostream>

using namespace std;

int main()

{

   int side1=0;

   int side2=0;;

   int side3=0;

cout <<"Enter side one measurement";

cin >> side1;

cout <<"Enter side two measurement";

cin >> side2;

cout <<"Enter side three measurement";

cin >> side3;

if(side1+side2>side3||side1+side3>side2||side2+side3>side1){

if (side1==side2 && side2==side3)

{

   cout <<"equilateral triangle"<<endl;

}

else if(side1==side2||side2==side3||side1==side3){

   cout <<"Isosceles triangle"<<endl;

}

else{

      cout <<"scalene triangle"<<endl;

}

}else{

   cout<<"No triangle";

}

   return 0;

}

Explanation:

The code is written in c++. It takes measurements of each side from users as input and check the types of triangle based on the following formula.

1. Equilateral Triangle

If all sides of a triangle are equal than it's an equilateral triangle.

2. Isosceles Triangle

If any two  sides of a triangle are equal than it's an Isosceles triangle.
