How the output is 0?[solved]

Question

https://code.sololearn.com/cGks15v1Y22F/?ref=app

Answer 1

because 1 and 2 are int, and 1/more than 1 result to 0...

Answer 2

Because in C++ and C (and, maybe, in some other programming languages using separate data types for integers and floating-point/decimals, excluding Python) operators with integers return integers: 1 / 2 * 10 * 10 = 0 * 10 * 10 = 0 * 10 = 0.

Answer 3

try to put 1.0/2 to compute floating division, you'll get 50...

Answer 4

Or `(float) 1 / 2 * b * h` (the same as visph has written, but giving the converting 1 to float work to the compiler).

Answer 5

dividing int by int result to int
dividing float by int or float give float

Answer 6

Atul, (continuing my first answer here); if one of the operands is float/double/long double (in C++ and C), the answer will be of this type. It was made for both precision and efficiency.

Answer 7

Atul

If you have specific data types like int, double, float, long in any programming language like Java, C, C++, C# then in case of 1/2 you will always get 0 because here 1 and 2 will be considered as integer.

But in case of some languages like Python, JS you will get in decimal.

Answer 8

🆄ⁿᵘˢᵘᵃˡ𝙥𝙚𝙧𝙨𝙤𝙣 operator precedence of * and / are same, so left to right rule apply ^^

Answer 9

So what should be done to make it 50?

Answer 10

Why after converting it into double it is showing the correct answer?

Answer 11

Ok thank you

Answer 12

🆄ⁿᵘˢᵘᵃˡ𝙥𝙚𝙧𝙨𝙤𝙣 expected output is 50, not 0.005...

first is computed 1/2 wich result to 0 as both numerator and divisor are int (but 0.5 expected)

then 0.5*10 = 5
then 5*10 = 50

Answer 13

Variable 'a' is declare as 'int' type so it having a capability to store the integer value.
1/2*10*10 ==0.005
But it contain only integer part of (0.005) that is zero(0).....✌️

Answer 14

visph According to operator precedence * first execute then / will be execute.

Answer 15

Amit Brar rgb is stand for red,green,blue color.it's value very from 0 to 255.
Where rgb(0,0,0)-->black
And rgb(255,255,255)-->white

Answer 16

🆄ⁿᵘˢᵘᵃˡ𝙥𝙚𝙧𝙨𝙤𝙣 you could now remove the unrelated answer about rgb colors ;)

Answer 17

z=2*10*10
a=int(1/200)=int(0.05)=0
