how to create random integers from a specific range in c language

//How to create random integers within a specific range in C langauge. 

srand(time(0))
number = (rand() % (upper - lower + 1)) + lower
//upper = max number
//lower = least number

how to genrate a random number in C

#include <time.h>
#include <stdlib.h>

srand(time(NULL));   // Initialization, should only be called once.
int r = rand();      // Returns a pseudo-random integer between 0 and RAND_MAX.

/** This random number generator using your
   own computer time to generate random
   number, the program is working so quick
   so you can't use a for loop to generate
   multiple numbers. even with a delay the
   program will run in a small jumps from
   number to another so the only way to
   properly generate random numbers is
   running the code multiple times         **/

random number c

#include <stdio.h>
#include <time.h>

int main(){
   /*this is the seed that is created based on how much 
  time has passed since the start of unix time. 
  In this way the seed will always vary every time the program is opened*/
	srand(time(NULL));
  	int max;
  	int min;
  	int n;

random number c custom rand

rand() % (max_number + 1 - minimum_number) + minimum_number
