Question

C++

1) Write a random number generator that generates random integers from -10 to 10.

2)Write a random number generator that generates random integers from 0 to 10.

Also can you explain how does it work if possible. Thank you.

Answer 1

1)

#include <iostream>
#include<stdlib.h>
#include<time.h>
using namespace std;

int main()
{
int n,x;
srand(time(NULL)); //It is used to initialize the pseudo random number by taking time as an argument
cout<<"Enter How Many Numbers"<<endl;
cin>>n;
cout<<"The Random Numbers Generated are"<<endl;
for(int i=0;i<n;i++)
{
x=rand() % 22 -10 ; // This will display Numbers from -10 to 10
cout<<x<<endl;
}

return 0;
}

2)

#include <iostream>
#include<stdlib.h>
#include<time.h>
using namespace std;

int main()
{
int n,x;
srand(time(NULL)); //It is used to initialize the pseudo random number by taking time as an argument
cout<<"Enter How Many Numbers"<<endl;
cin>>n;
cout<<"The Random Numbers Generated are"<<endl;
for(int i=0;i<n;i++)
{
x=rand() % 11 ; // This will display Numbers from 0 to 10
cout<<x<<endl;
}

return 0;
}
