Question 20: Because the fun() function was not defined before, it cannot be called directly in mian(), if fun() is defined before mian(), then it can be called.

Everything else, it's not difficult, you can do it if you read it, it should be basically right, if you have any questions, let's read the book.

It's so unkind, it's 0 points.

The score is also too few!!

Extra points, I'll do it for you!!

This is at most a junior high school C language paper.

You at least send a picture.,I'll take a look.,I'll do it for you if I can.,Anyway, now I have nothing to do.,It's okay.。

1 2 Two points to determine a straight line Let's look at it first.

I promise not to tell you about the teacher.

1. Calculations.

1. Write the number directly. (10 points).

2. Vertical calculation. (18 minutes).

Lots keep 2 decimal places) (Lots keep 2 decimal places).

2. Calculate the following questions, and use simple methods to calculate those that can be calculated simply. (24 points) 3-column calculation. (8 points).

What is the quotient of 14 multiplication and division, what is the product?

The product of two factors is, what is one factor and what is the other?

2. Fill in the blanks (20 points).

1. When calculating, first expand the divisor and the dividend at the same time ( ) times, and then calculate the result ( ) 2. When one factor is 1 hour, the product is greater than another factor (except zero) (when one factor is larger than 1, the product is larger than another factor (except zero) (.)The product of 26 has ( ) decimal places.

4. In this problem, if you expand it by 10 times, to keep the product unchanged, 13 must be ( ) 7 hours = ( hours ( ) minutes.

Kilogram 60 g = ( kg.

The meaning of 7 is to seek ( ).

7992 keeps two decimal places, which is approximately ( ).

The quotient of 52 with two decimal places is ( ).

3. Judgment. (Correct in parentheses "incorrect" "incorrect" 4 points) 1, infinitesimal decimals are cyclic decimals. （

2. When shopping, the payment yuan means that it is accurate to the minute. （

3. Multiplying a number (except zero) by 100 has the same result as dividing this number.

The quotient of 8 is a cyclic decimal. （

Fourth, the application of the problem. (16 minutes).

1. Xiaohua bought kilograms of beans in the vegetable market, and after paying 13 yuan to the salesman, he recovered the yuan. How much is a kilogram of beans?

2. Iron and steel plants save tons of coal in July, and the amount of coal saved in August is more than that of July, and how many tons of coal are saved in August?

4. How many hours does it take for a car to travel 210 kilometers in an hour, and travel 318 kilometers at this speed?

5. Food for thought. （ 20 ）

1. A three-digit decimal place, rounded to the hundredth place, is approximately this three-digit number.

The decimal maximum may be ( ) and the smallest may be ( ).

2. Fill in the " ", what is the maximum quotient? What is the minimum?

Quotient maximum: (quotient minimum: (
