Exercise array 02

1. Write a program which prints the letters in a char array in reverse order. For example, if the array contains {'c', 's', 'c', '2', '6', '1'}the output (to the terminal) should be "162csc"

2. Write a  program : declare a char array and the size of the array (of type char). This function counts the number of digit letters in the char array.

3. Write a program that counts the number of words in a string

4. Write a program that accept two string, after checking if string1 equals string2 then print 'string 1 equals string2', else print string1 less than or greater than string 2.

5. Write a function that scans a character array for the character - and replaces it with _

Exercise_array 1(day 5)

1. Write a program that asks the user to type 10 integers of an array. The program must compute and write how many integers are greater than or equal to 10.

2. Write a program that asks the user to type 10 integers of an array. The program must output the largest element in the array, and the index at which that element was found.

3. Input values are accepted from the user into the array. Displays highest of the entered values. Prints average of values entered.

4. Write a program that accepts the following numbers in an array and reverses the array

6. Write a program that asks the user to type 10 integers of an array and an integer V. The program must search if V is in the array of 10 integers. The program writes "V is in the array" or "V is not in the array".

7. Write a program that asks the user to type 10 integers of an array and an integer value V. The program must search if the value V exists in the array and must remove the first occurrence of V, shifting each following element left and adding a zero at the end of the array. The program must then write the final array

8. Write a program that asks the user to type 10 integers of an array and an integer value V and an index value i between 0 and 9. The program must put the value V at the place i in the array, shifting each element right and dropping off the last element. The program must then write the final array

Exercise with ball...

Đề bài đơn giản là quả bóng sẽ bị rơi xuống,chúng ta cần cho nó k bị rơi xuống quá màn hình nữa.

Ở bài này,chúng ta sử dụng câu lệnh "if",đặt điều kiện cho sự di chuyển của quả bóng,làm nó k rơi xuống nữa.

Dùng "if" với điều kiện khi ball vượt quá tọa độ 370,nhận đc kết quả tốc độ đổi từ 2 xuống -2(tức là ball đi ngược lên trên)

Tương tự,đặt thêm 1 điều kiện để ball rớt xuống khi qua toạn độ y=30,tránh để ball bay quá màn hình.

  b=7

  c=15.75

  d=4

  e=2

  f=5.6
