What s wrong with the question? Thank you, what s wrong with the third question?

LZ: Are you comfortable to look at after making it up? Nothing""...

It's a clan year clear (k 2,0).

The period of tanx is 2, (k, 0) is also a trillion ago, but no hail is the smallest period.

1/a ∫1/(x+b/a)dx =1/a lnabs（x+a/b）+c

This step is wrong, how can b a be written as a b?

The rest is right.

Answer: There is no categorical discussion, a=0 and a≠0 cases.

There is nothing wrong, how can it be wrong?

#include

void main()

int a[3][3],i=1,j=2,t=2;

a[1][1]=1;

a[1][2]=2;

for(;i!=0;)

i=i-1;

a[i][j]=++t;

for(;j!=0;)

j=j-1;

a[i][j]=++t;

for(;i!=2;)

i=i+1;

a[i][j]=++t;

for(;j!=2;)

j=j+1;

a[i][j]=++t;

for(i=0;i<3;i++)

for(j=0;j<3;j++)

printf("%4d",a[i][j]);

printf("");

You mainly have an error in the for statement, the difference between ++t and t++ is not clear, with t++, t should be defined as 3, and the maximum output of the for statement can only be 2, and there will be no 3, so it is less than 3

return 0 is followed by one less ; A semicolon indicates the end of the line**.

There is also a } curly brace missing at the end, and the fourth line.

#include

int main()

There is one less brace to the right here.

return 0 is followed by a curly brace that is ignored.

#includeint main(void)

return 0 is followed by a semicolon and a curly brace mark.

Hello! Solution: The end of the slag is placed on the ground, and the ground bears the weight of 16N, so the spring type does not show the weight of the A.

Since the B end is suspended and the spring bears the weight of B, the spring scale shows the weight of B, so it is 12N.

Yours is the driving force of my service.

Good luck with your studies!

If you just change it to syntactically correct, just change int* func(int x) to int func(int x). Also, if you want to run, you have to have a main function.

If prime numbers are required, they can be changed as follows.

#includeint func(int x) return 1;}

What function should be fulfilled, find the greatest common factor?

There is a problem with the function definition.

int* func(int x）

Change to int func(int x) and change the return type to int, not a pointer.

Is this the complete program?! I didn't see the main function.,Didn't you type?!。

Why do you want to return an int pointer?! Don't you return two values, 0 or 1??? Just use int func(int x){} and you're good to go.
