Question

Recall that the C++ statement rand() $10 returns a random integer with a value that ranges from 0 to 9. Write C++ code that will generate 100 random integers from 0 to 9 and will determine how many times the number 5 is generated.

Answer 1

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main()
{
    srand((unsigned)time(NULL));
    int count = 0, n;
    cout<<"100 random numbers are:"<<endl;
    for(int i = 0;i<100;i++){
        n = rand()%10;
        cout<<n<<" ";
        if(n==5){
            count++;
        }
    }
    
    cout<<"\nNumber of times 5 generated = "<<count<<endl;
       return 0;
}
