What do you mean by the following functions? Have the following functions?

label2rgb()

Function: Convert marker matrix to RGB image. That is, according to the different values of the label matrix, it is transformed into different colors or grayscales.

call format rgb = label2rgb(l, map, zerocolor) ; That is, the form in the title.

where l is the marker matrix to be converted, the map can be a @jet or @gray, the @gray is a grayscale bar, and the @jet is a color bar, that is, it becomes a color image, and @jet represents a handle reference through jet'jet' map。

zerocolor is the color marked with 0, [.].5 .5 .5] Set the color of marker 0 to [ . The default value is [1 1 1], which is white.

Which of the following statements is true about functions?

a.A Zen C program can only consist of one function.

b.The same function can be called by one or more functions multiple times.

c.Functions can be defined nested.

Functions, like other functions, can be called against each other.

Correct Answer: Herb Ant B

Select a to find the length of the stringswhile(*t++) does not exit the loop until the pointer t points to the string terminator.

t--;The pointer is moved forward by one bit, that is, the pointer points to the last valid character.

return（t-s）;Returns the address difference between the last valid character and the first character, that is, the length of the string.

It is not advisable to take anything else that is available as of the time of this issue, and the diagram below shows the correct steps to calculate this indefinite integral using the partial integral method.

To calculate the indefinite integral of the round of prudence, we know that f(x) is a continuous function in the whole interval, so the original function of f(x) must exist.

However, the existence of a primitive function does not mean that it can be expressed in the form of a basic elementary function.

Therefore, we can consider using Taylor's formula to make f(x) a power series, calculate its convergence domain, and then calculate its indefinite integral.

Using McLaughlin's formula to partially f(x)=e(x2), the shedage can be rewritten as a power series.

Find the method according to the convergence domain of the power series:

Find the convergence radius r:

Then the convergence domain of the power series in is i

According to the properties of the summation function of the power series chain:

Indefinite integrals in a problem can be calculated:

The convergence domain of the power series in this result is the same as that of the original series, both of which are i

a.If a function is defined and then called, it must be stated before it is called.

b.If the function is called first and then defined, it must be stated before the call is made.

c.Regardless of the order in which the function is defined and called, it must be stated before the mess is called.

d.Regardless of the sequence in which the function is defined and called, the one who does not make a noise must explain it before the call.

Correct answer: B

The following statement is true: in the function ().

a.Additional functions can be defined and called.

b.You can call but not define other Wanghui functions.

c.Other functions that cannot be called, but can be fixed.

d.No other functions can be called or defined.

Correct Answer: Sleepiness refers to hunger B

Answer]: cc. 【Analysis】The inline function is not a function defined inside another function body, but the inline is placed before the function type in the function definition; The last statement of the function body can be arbitrary; The compiler does not distinguish overloaded forms based on the type of value returned by the function, option d is wrong.

Criterion C requires that a prototype of a function must be declared before it can be called.
