The float value usually consumes more space in storage as compared to the short int. The only difference is, we will need to explicitly define that the value we are expecting from the rand function should be a float. The approach to generating the random float value is similar to the approach for generating the integer number. As we didn’t define the return value of the random number explicitly, it will give us an integer number.
The function rand() generates a random number which is assigned to the variable rand_num. Rand_num is the variable that is used to store a randomly generated number. As the time changes every time, the value of seed will change every time the program will be executed, helping us to generate a random number every time the program is executed. In this program, we have used time.h header file which is used to leverage the system time in generating the random number. The randomly generated number is 1804289383. Printf("The randomly generated number is”) In order to generate the Below is the program to generate the integer random number. If the seed value is kept on changing, the number generated will new every time the program is compiled else it will return the same value every time that was generated when the program was executed first. A seed is a value that is used by rand function to generate the random value. The rand() function in C could be used in order to generate the random number and the generated number is totally deleting seed. If the developers add some logic with it, they can generate the random number within a defined range and if the range is not defined explicitly, it will return a totally random integer value. Every time it is called, it gives a random number.
The rand() function is used to generate a random number. Time is something that keeps on changing and can also be considered as something that can help in getting a random seed value every time and to use time in the program we have to use time.h header file.
If the requirement is to have the new random number generated every time the program executes than we have to make sure that the seed should change whenever the program runs. Though the rand function is supposed to generate the random value, it stuck to generate the same value every time the program is executed and it may happen due to the constant seed value.

Based on the requirement one can generate the number belongs to integer, float or double data type. Every time this function is called, it generates a totally random number. The developer needs to mention the stdlib.h header file in the beginning of the program in order to leverage the rand function.
This function comes predefined in C and can be implemented in the program using stdlib.h header file. In the C programming language, we have a function called rand, which helps in generating the random number. One can define the function of their own way to estimate or generate the random number while there are inbuilt functions in any of the programming language that generates the random number. There are several approaches to generate the random number using any of the programming languages. What is Random Number Generator Functions in C? We will be focusing on the inbuilt function that is provided by C in order to generate a random number. In this article, we will see the program implementation of random numbers generated using the C programming language. Though it looks random to the user the programming language offers us the mechanism to define the range of the random number. In the same way, sometimes we need to have the application generate any random number which could be processed further to get the supposed output. For instance, to get the current timestamp the application uses an inbuilt function to fetch it from the system. Usually, the inputs are provided by the user but sometimes the program has to pick the input by itself. In order to generate the expected output, the program must need the proper input.
