In C language, arrays are defined as follows:<\/p>\n

    \n
  1. Static definition: Use the following syntax to define arrays outside of a function or in the global scope.<\/li>\n<\/ol>\n
    data_type array_name[array_size];\r\n<\/code><\/pre>\n
    Can you please help me with my homework? <\/p>\n

      \n
    1. Dynamic definition: use the following syntax to define arrays within a function:<\/li>\n<\/ol>\n
      data_type *array_name;\r\narray_name = (data_type *)malloc<\/span>(array_size * sizeof<\/span>(data_type));\r\n<\/code><\/pre>\n
      – “I need to see the doctor because I’ve been feeling unwell lately.”
      \n– “I must go to the doctor as I’ve been feeling sick recently.”<\/p>\n
      int<\/span> *numbers;\r\nnumbers = (int<\/span> *)malloc<\/span>(5<\/span> * sizeof<\/span>(int<\/span>)); \/\/ \u5b9a\u4e49\u4e00\u4e2a\u5305\u542b5\u4e2a\u6574\u6570\u7684\u52a8\u6001\u6570\u7ec4<\/span>\r\nfloat<\/span> *grades;\r\ngrades = (float<\/span> *)malloc<\/span>(10<\/span> * sizeof<\/span>(float<\/span>)); \/\/ \u5b9a\u4e49\u4e00\u4e2a\u5305\u542b10\u4e2a\u6d6e\u70b9\u6570\u7684\u52a8\u6001\u6570\u7ec4<\/span>\r\n<\/code><\/pre>\n
      Please remember to free the memory space by using free(array_name) after using the dynamically allocated array.<\/p>\n
        \n
      1. Assignment by equals sign: Assign initial values to array elements at the same time as defining the array.<\/li>\n<\/ol>\n
        data_type array_name[array_size] = {value1, value2, ..., valueN};\r\n<\/code><\/pre>\n
