The concept of these types of grammar must be mastered and is a very important test center. For these

Finding the root x^3-5x^2+16x-80=0 of a three-order equation by using the chord-truncation method#include #include float f (float x)//define sub-function f (x) = X^3-5x^2+16x-80, when f (x) →0, then x is the real number root of the request;{Float y;Y= ((x-5.0) *x+16.0) *x-80.0;return (y); Returns the value of f (x)}Flo

In the previous section, the flowchart we drew, remember? Judging the part we will, the difference cycle, below I will introduce three kinds of commonly used loops.Loop structure while loop (when looping, at least my C language teacher calls it)Let's introduce the syntax, as follows while (conditional expression) { // Here is the loop body, when the above condition expression is true, the loop body is executed, otherwise exits }While followed by a conditional expression, the loop is executed

1. alpha is used to set transparency. Its basic attributes are filter: alpha (opacity, finishopacity, style, startX, startY, finishX, finishY ).Opacity indicates the transparency level. The value 0-100 indicates that the opacity is completely transparent, and the value indicates that the opacity is not transparent.Finishopacity is used to set the transparency at the end to achieve the gradient effect. The value range is also
