Question

c++ programming help

Answer 1

so z is a float variable, it says that x = y * z is bad programming style but i don't know why.

Answer 2

x = y * z; is the actual statement, also all the other variables are int

Answer 3

Sorry brother, am not made for math...

Answer 4

umm this isn't math

Answer 5

the problem doesn't lie in the math

Answer 6

i believe i might have to put the float variable before the int, like this x = z * y;

Answer 7

Dude this is beyond me...

Answer 8

otay

Answer 9

why dont you see the error it accumulates in c++

Answer 10

it's doesn't have bad syntax just bad programming style

Answer 11

atleast i think

Answer 12

add y*z to itself 10000 times and see the difference between z*y 10000 times

Answer 13

ur such a troll

Answer 14

i dont know how C++ floating point arithmetic works, it might do int * float and float * int in different ways

Answer 15

why?

Answer 16

cause reasons

Answer 17

jk

Answer 18

oh well ill just post what i think

Answer 19

turn in*

Answer 20

not post

Answer 21

you should google it im sure you can find these kinda questions there a lot

Answer 22

Mixing and matching int and float in a calculation is generally not considered a good practice. For one there will be truncation error in the case when int y = 2; float z = 3.2
then int x = y * z will be 6.

But if you must mix them, use an explicit cast.

Here is an example of mixing and matching int and float that gives different results:
int p = 3; int q = 2; float x = 7.3; float result;
result = x + p/q; (result will be 8.3 because p/q = 3/2 is an integer division that will be truncated to 1 which when added to 7.3 yields 8.3)
result = x + (float) p / (float) q; (result will be 8.8)

Answer 23

For C++, ask in comp sci section.
