Write C++ statements to do the following tasks: (Assume we already have using statement) (15%) (A)Declare a double array "x" with 3 elements. Initialize the array as [1.1 2.2 3.3]. (B)Use for loop, and/or break, continue commands to display 1,2, 4,5,6(skip3) on the screen. (C)Enumerate the 7 days of a week(Mon=1,Tue=2,Wed=3,Thur=4,Fri=5 Sat=6,Sun=7). 2.Write the functions.(Assume we already have using statement.And libraries are included) (40%) (A)Create a function called "Function1" that inputs a character array "s1", copies the first half of "s1" into character array "s2", and copies the second half of "s1" into character array "s3". The function also has an interger inputs "s_size", which is the size of "s1". (B)Create a function called "Function2" that inputs an integer "SCORE" and returns a character. If "SCORE" >=80, return A. If 80>SCORE>=70, return B. If 70>SCORE>=60, return C. Otherwise, return F. You must use "switch" in this problem. (C)Create a function called "Function3" that inputs an integer N. The function returns N if 10<N<15 or 20<N<25. Otherwise the function returns 0. You should not use nested if (Hint: use logical operators). (D)Create a function called "Function4" that returns an even integer number Y. In the function, the program prompts the user to input an even number. If the input is valid, the program will ask the user to input until it has a valid input. You must use "do while" in this problem. (E)Create a fuction called "Function5" that returns a 10 by 15 2-D array(10乘15的二维阵列). Fill in the array with non-duplicated random numbers between 600~1000. 3.(24%)Selection Sort (A)Implement a function "swap(double*,double*) that swaps two data elements.(8%) (B)Use "recursive" method to implement selection sorting with function "selectionSort(int[],int)" and "swap(double*,double*). (Hint: the selection sort in the textbook is NOT recursive, it's iterative). With these 2 functions, write a complete program to sort [34,56,4 10,77] from the smallest to the largest.(16%) 4.(16%)Show the output If you think there is a syntax error, just write 'ERROR' as your answer. int x = 5; inline void F1(void) { int x = 20; x=x+1; cout<<"(F1)x= "<<x<<endl; } inline void F2(void) { static int x = 25; x=x+1; cout<<"(F3)x="<<x<<endl; } inline void F3(void) { x=x+2; cout<<"(F3)x="<<X<<endl; } int main() { int y = 10; int&x=y; cout<<"(A) x="<<x<<",y"<<y<<endl; F1(); F2(); F3(); cout<<"(B) x="<<x<<",y="<<y<<endl; { int x=15; cout<<"(C) x="<<x<<",y="<<y<<endl; } cout<<"(D) x="<<x<<",y="<<y<<endl; F1(); F2(); F3(); cout<<"(E) x="<<x<<",y="<<y<<endl; return 0; } 5.(10%)Show the output if you think there is a syntax error, just write 'ERROR' as your answer. Assume the address of x is 600000. The size to store an address is 4 bytes. The size to store an integer is 4 bytes. int x[]={1,3,5,7}; int *y=x; int i=1; cout<<"\n(a1)="<<&x[3]; cout<<"\n(a2)="<<y; cout<<"\n(a3)="<<*x+2; cout<<"\n(a4)="<<=(y+1); *(y++)=2; x[2]=4; x[3]=0; cout<<"\n(a5)="<<x[++i]; cout<<"\n(a6)="<<*(x+1); cout<<"\n(a7)="<<x; cout<<"\n(a8)="<<*(*(&y)); cout<<"\n(a9)="<<*(&(*y)); cout<<"\n(a10)="<<++y; --
