C++ & Math

Quick Question: Im 16 years old student who is bad at maths but want to learn programing and software engineering ! Can i learn C++ without math or other langueges ?

for me programming have less to do with math, i'm not very good in math aswell.
The programs themself and how they works, have alot to do with math and depeding on what u want to do, u need to calculate something here and there, but in core i would say, you can learn C++ without being good in math. Some calculations like units * sizeofUnits you can not avoid, but u dont need even to know the result xD

Maths and programming share a similar way of thinking, so if you can't wrap you head around how math even works you're going to have a hard time learning programming. That does not mean it's impossible, it might even make you good at math. When it comes to how much math you actually need in programming it depends on what you're programming. If you're aiming for physics or game development then math is fundamental. For everything else it's more or less just basic arithmetic.

I agree with @Biesi I've heard that other things require more math than others for example mobile development i heard does not require as much math as lets say creating a game. So it really depends on what your going for

I also have good memory if that can help me in any way im bulgarian and i only learn english from youtube videos

Depends on the kind of website again. If it's math related it requires more math. When it's not, then you're good with calculating margins and boundaries that are just simple arithmetic operations like 1200 - 5 * 20. For game development it can ramp up to complex matrix stuff as well as 3D calculations. It also makes a difference whether you're using an existing game engine that has the math stuff already implemented or whether you're creating your own engine and have to calculate the distance between two points in three dimensional space (e.g.). Nothing you wouldn't be able to look up, but you need to understand concepts and basics of math.

I don't recommend you start with C++ if it's your first language. As C++ is one of the harder ones to learn and get a grasp of. Learn some easier languages like C# / Java etc. And yes, Math is extremely important for when you get into complex algorithm and what not.

Math has nothing to do with programming. Just because you need to know basic math (divisibility, addition and subtraction, arrays etc) it doesn't mean you need math in order to code. You don't need mathematical formulas and knowing how to solve equations in order to develop a game for example.

Sure, if all you intend of ever making is 50 line console applications then you can get away without knowing any math, but anything that actually does something usefull uses math in some way or form.

Also stating that math has nothing to do with programming is like stating physics has nothing to do with engineering. It's ignorant and just flat out wrong.

I'm assuming when say "basic math" you are referring to basic arthimetic such as addition and multiplication.

I can think of several fields where having knowledge of concepts such as linear algebra, probability, set theory and number theory are essential. These forms of math certainly don't fall under the concept your "basic math." Ill say it again, if your working on basic programs as a hobby then sure, having no grasp of math could be fine.

So it's just not true, that it counts only for hobby programmers.

yeah depends on what you mean by mathematics.

as for game developing, you probably need basic high school stuff. like pythagoras theorem, trigonometry, linear algebra. those are the only ones i can think of on the top of my head. you might also need interpolation depending on what you're doing for smoothness - or u can just steal those off peoples ******

The most difficult calculations i ever had to do, was world 2 screen

Code:

	bool	world_to_screen(v3 pos, v2& out)
	{
		v3	tmp;

		float*		viewMatrix	= CHooking::m_viewPort->fViewMatrix;

		tmp.x	= (viewMatrix[0] * pos.x) + (viewMatrix[4] * pos.y) + (viewMatrix[8] * pos.z) + viewMatrix[12];		//row 2
		tmp.y	= (viewMatrix[1] * pos.x) + (viewMatrix[5] * pos.y) + (viewMatrix[9] * pos.z) + viewMatrix[13];	//row 3
		tmp.z	= (viewMatrix[2] * pos.x) + (viewMatrix[6] * pos.y) + (viewMatrix[10] * pos.z) + viewMatrix[14];	//row 4

		if(tmp.z < 0.001f)
			return false;

		tmp.z = 1.0f / tmp.z;

		tmp.x *= tmp.z;
		tmp.y *= tmp.z;

		int32_t	w	= (int32_t) CHooking::m_resolution->w,
				h	= (int32_t) CHooking::m_resolution->h;

		out.x	= ((w / 2.f) + (.5f * tmp.x * w + 1.f)) / w;
		out.y	= ((h / 2.f) - (.5f * tmp.y * h + 1.f)) / h;

		if(out.x > 1.f || out.x < 0.f || out.y > 1.f || out.y < 0.f)
			return false;
		return true;
	}

and guess what. even this calculation is to find and if not.. it's Mult, Div, Add and Sub nothing special.
But maybe we 2 have just a different defintion of "Math".
For me, even Regular Expressions are not math, but they are technically even part of math.
Just pattern match scanners.
