" The purpose of the parentheses is to force the eval function

name [array length]Initialization The definition is initialized directly, such as: Int n[1]={0}; Implemented through a looping structure, such as:int n[10];for(i=0;i 1.2 A one-dimensional array in-memory structure? can draw a description. What does an array name mean?1.3 Why use arrays?Arrays are the same type of data uniformly compiled into a group, so that the array name + index number

Array storage: The system allocates a contiguous storage unit in an array of memory, each of which is arranged in the order of the subscripts from small to large; One-dimensional array in-memory structure: see the first C language textbook 149-150 pages; The arra

the previous number is larger than 1.5 What is the binary search method? It differs from the order lookup method? Each time the interval is divided into two halves, judging the area to be asked, shrinking the range. The operation efficiency of dichotomy is higher, and the method of sequential use is more direct but less efficient. 1.6 How are two-dimensional arrays defined and initialized? Definition: Array type array name [array length] [array column lengths]

right, into the corresponding interval, repeat the above stepsDifference: When the data is long, the binary search method is efficient and the sequential lookup method is inefficient.The binary lookup method requires the data to be ordered, and the order lookup rule does not have this requirement1.6 How are two-dimensional arrays defined and initialized? DefinedTwo-dimensional arrays are defined in the fol

to this position, if a[mid]>x, then the new search interval is a[1..mid-1] If a[mid]The binary lookup method is applied to the sorted array, it is not necessary to compare each element, the speed is fast, and the sequential lookup method is used to repeat the group1.6 How are two-dimensional arrays defined and initialized?Definition: Type an array group name [President] [column length]Initialize: The initial value of the branch is assigned: int a [3] [3] ={{3}, {4,5,6}, {7,8,9}}, the order is a

element from the middle of the table. If a consistent element is found, the lookup succeeds. If the intermediate element is smaller than the target element, the second half of the table is still found using the binary lookup method, whereas the middle element is larger than the target element, then the first half of the table is looked up1.6 How are two-dimensional arrays defined and initialized?

To uniquely identify an element in a two-dimensional table, two subscripts must be given. By habit, the first subscript determines the line number where the element is located, and the second column determines the co
