Description

To generate random number between given range both in c 
and java follow the program.

C/C++

/* C Program to generate Random number in a given Range */
//Save it as GenerateRandomNumber.c

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main(){

    int i, countNum, lower, upper;

    printf("Enter the number of random number you want : ");
    scanf("%d",&countNum);

    printf("Enter the lower limit : ");
    scanf("%d",&lower);

    printf("Enter the upper limit : ");
    scanf("%d",&upper);

    //To genearate new set of numbers everytime use srand funtion
    /*By using srand function current time is used which will always be
      different so everytime a different set of numbers is generated.*/
    srand(time(0));

    printf("The numbers in a given range\n");
    for(i=0;i<countNum;i++){
        //To genearate new set of numbers everytime use srand funtion.
        //After rerun program, only same set of numbers will be generated everytime.
        //To genearate new set everytime use srand funtion.
        int number = (rand() % (upper - lower + 1)) + lower;
        printf("%d ", number);
    }

    return 0;
}

Input:
Enter the number of random number you want : 3
Enter the lower limit : 1
Enter the upper limit : 10

Output:
The numbers in a given range
8 6 5

Java

/* Java Program to generate Random number in a given Range */
//Save it as GenerateRandomNumber.java

import java.io.*;
import java.util.Scanner;
import java.util.concurrent.ThreadLocalRandom;

public class GenerateRandomNumber {

    public static void main(String[] args) {

            Scanner scanner = new Scanner(System.in);
        
            int i, countNum, lower, upper, number;

        System.out.println("Enter the number of random number you want : ");
        countNum = scanner.nextInt();

        System.out.println("Enter the lower limit : ");
        lower = scanner.nextInt();

        System.out.println("Enter the upper limit : ");
        upper = scanner.nextInt();
        
            System.out.println("The numbers in a given range");
            //Generating new set of number between lower and upper limit
        for(i=0;i<countNum;i++) {
        	
        	number = ThreadLocalRandom.current().nextInt(lower, upper + 1);
        	
        	System.out.println(number);
        }
    }
}

Input:
Enter the number of random number you want : 
3
Enter the lower limit : 
1
Enter the upper limit : 
10

Output:
The numbers in a given range
8
6
5
