C Program to Generate Random Numbers with in a Range of values

In this tutorial you will learn how to generate Random numbers between a range of numbers using rand() srand() and time() functions in C Programming language.

In c language rand function is used for getting random numbers. To make sure that we get different sequence of random numbers for separate runs, we use srand function and pass the system time in seconds using time function.

To use rand and srand functions, we need to include stdlib header file and for getting time using time function we need to include time.h header file.

Dude, i was working for over three hours, and you're the only one who got the solution ! I love you ! And i give you my like, take it ! :)

Beginner tip: Beware of testing your code in rapid succession with the use of 'srand(time(NULL))'. I thought I was having a problem during testing where the numbers were not "truly random" when in reality my problem was that I was running the program over and over so fast that it would often be run multiple times in the same second, so the second value of time would not change, and therefore the random number generated would be the same.

That being said, thank you @LearningLad. This is by far one of the simplest and most easily understood methods to generate a random number that I have seen, AND you even included an easy way to add upper and lower limits. Very much appreciated.

You're the only one who says to dislike the video if we don't like it

But I've became a huge fan of your explanation sir. that's really crystal clear sir...thank you for debugging my code sir

[sayukiTechki]

wow, your explanation is fantastic, you just made my learning C programming more enjoyable.

i was trying to make a hangman game where i will give some words in a text file associated with some random number. my program will randomly take a word and ask user to guess. this definitely helped.

Love you my man😘

I would like to ask if the random number is let's say 400, wouldn't the resulting no. equal to 4? or are we to assume that it would always be bigger than that?

Thank you so much!! Greetings from Italy :)

This is of great help, thank u for making these videos

What if you need a random number from 1 to 1 million, with a seed 179. The first iteration is 545994 but I can't get it.
I'd like to know how to do this.
