How to use arrays and hash tables? Summary of array and hash table example usage

Working with Arrays and Hash Tables In C, there are two different basic methods for storing any number of independent data elements in a structure. There are pros and cons for both methods. Vector Vs. The writing of linked list applications is usually based on the selection of the characteristics of a specific type of data, how much data needs to be stored, and how fast it needs to be retrieved. In order to have an equivalent understanding, let's first take a brief look at these storage mechanisms .Vector Vectors are a continuous memory space that contains data at regular intervals. The most common example of a vector is a string variable (char * or char []), which contains a sequence of characters (bytes) one after another. .char foo[4] = "bar";Here, foo[0] contains the character 'b'; then, you will find the character 'a' in foo[1], and finally in foo[3] is a The null character '\0'. The usage of storing pointers to other structures into vectors is almost ubiquitous, such as in
