![]() ![]() We will define four character arrays in which the first two will be of length 26 and contains the uppercase and lowercase English alphabets, the third array will be of length 10 and contains all the numeric digits, and the fourth array will contain the special characters like etc.Initially, we are going to take user input which will define the length of the password the user needs.The steps to build this project are not much complicated and are very straight. How are We Going to Build the Survey Form? To learn about the time function please refer to the article Library Functions in C.To learn about the srand() and rand() functions please refer to the article Random Number Generator in C.Also, we are going to use the time() function from the time.h library which we will discuss later in this article. As we are going to take elements randomly we are going to use the function srand() and rand() function of C.To learn about the if-else statements please refer to the article if-else Statement in C.We have different types of characters and so add them to the character array we need some cases and to execute that we need to learn about if-else statements.To learn about the for loop please refer to the article For loop in C.To create the final password of a given length we need to traverse over the loop which may be a for loop or while loop.To learn about the arrays in C please refer to the article Array Data Structure.To learn about the variables declaration please refer to the article Declaration of Variables in C.So, we need to learn about the strings and variables in the C programming language. First of all the final output will be the string or character array which will be consists of the characters such as lowercase and uppercase English letters, number, and special characters.To build this project we need to go through some topics to get some prior knowledge of them for that we will discuss them in brief and there will be some references of articles which are beneficial if you are not experienced in them: If the password we are getting is not unique then there are high chances that the password of the users can be detected by the others.Īlso, we need to create the script in a way that there are a large number of outputs it can generate because if there are fewer passwords then by just brute force the passwords of the users can be generated and it will not work efficiently. Our goal is to get the output completely random and unique each time. In this project, we will build a script in C programming language that will take a single integer as an input and provide a string of random characters as the output. We are going to create a script in the C programming language which will generate a random password of the required length using the different sets of characters and this script will surely provide a unique password for each call. Passwords are the main key to stopping the security breach that’s why passwords must be unique and strong. ![]() In the internet era, to use most websites or apps, users need to create an account, and for the users' privacy, they must log in with a username and password.
