Question

( C language only )Generate a function  called randomnum(n,m,neg); where n and m are the lower and upper bounds for the random number;

the generated number is negative if a variable named neg is true .These numbers should be non-zero with a maximum absolute value of 15

. You must use bitwise arithmetic to calculate the modulus of the random numbers

Answer 1

Code:

#include<stdio.h>  // library file for standard input/output
#include<stdlib.h>
#include<stdbool.h> // very important to include if you want to pass value of neg
#include<time.h> // important for generating random numbers

int randomnum(int n,int m,bool neg){
    
    srand(time(0));  // used to maintain uniqueness of numbers generated
  
    int num = rand()%(m-n+1)+n;  // generating a random number within (n,m)
    if(num>15)return 0; // if its greater than 15, return nothing
    if(neg==true){  // if neg is true, return the negative of the number
        return -1*num;
    }else{
        return num;
    }
  
    return 0;
}
// driver code
int main(){

    // generate two random numbers
    int b = randomnum(5,10,false);
    int c = randomnum(1,5,true);

    int res = b & c; // apply bitwise & to calculate the modulus
    printf("%d",c); // print the result

}        

Output:

Note: Your question was a bit unclear on the bitwise part so if this what you were looking for, its all good or comment below if you need something to be changed.
