This question is related to marketing, it can't be said that Pentax and Nikon don't have that strength, but they are really designed and produced, what will happen to the market? Can the cost be controlled? There are questions about how well it will be sold.

Our country once developed and produced a lens with a larger aperture in the 70s, so what? The same cannot be commoditized. To be honest, no matter what the current optical company, if you don't care about the cost and practicality, even a zoom lens like 24mm can be produced, but its cost will be unimaginably high, and the volume will be too large to use.

Besides, not only Nikon and Pentax, but also Minolta (Sony), and Germany's optical giant, Carl Zeiss and Leica, do not have either, so does that prove that they are inferior to Canon? Hehe.

You're in an endless loop, you have expression 3 there, i=2, and then you judge that i<5 will always hold.

In this way, s should be equal to 2

The final result is 10 after the cycle

This problem relies on nesting do while ...... in a for looploop, when i=1 enters the do while ......loop: s=s+i*i, the actual effect is equivalent to s=s+1 loop, and when the loop reaches s=10, the do while ...... pops uploop.

You have a problem with this program, you wrote the original question, especially the letters, and you didn't understand it.

In this case, the numerator and denominator are multiplied by a number.

Here we need to remove the complex number in the denominator, that is, multiply by (1-i)5 (1+i)=(5*(1-i)) 1+i)(1-i))=(5-5i) 2

5/2-5i/2

The numerator and denominator are multiplied by 1-i, which only needs to be multiplied by the conjugate plural of the denominator.

The numerator and denominator are multiplied by (1-i), and the denominator can be simplified using the square difference formula!
