Md command, (make directory) creates a directory. It's a subdirectory when you md under a directory.
Answer:
Explanation:
#include<iostream>
#include<ctime>
#include<bits/stdc++.h>
using namespace std;
double calculate(double arr[], int l)
{
double avg=0.0;
int x;
for(x=0;x<l;x++)
{
avg+=arr[x];
}
avg/=l;
return avg;
}
int biggest(int arr[], int n)
{
int x,idx,big=-1;
for(x=0;x<n;x++)
{
if(arr[x]>big)
{
big=arr[x];
idx=x;
}
}
return idx;
}
int main()
{
vector<pair<int,double> >result;
cout<<"Enter 1 for iteration\nEnter 2 for exit\n";
int choice;
cin>>choice;
while(choice!=2)
{
int n,m;
cout<<"Enter N"<<endl;
cin>>n;
cout<<"Enter M"<<endl;
cin>>m;
int c=m;
double running_time[c];
while(c>0)
{
int arr[n];
int x;
for(x=0;x<n;x++)
{
arr[x] = rand();
}
clock_t start = clock();
int pos = biggest(arr,n);
clock_t t_end = clock();
c--;
running_time[c] = 1000.0*(t_end-start)/CLOCKS_PER_SEC;
}
double avg_running_time = calculate(running_time,m);
result.push_back(make_pair(n,avg_running_time));
cout<<"Enter 1 for iteration\nEnter 2 for exit\n";
cin>>choice;
}
for(int x=0;x<result.size();x++)
{
cout<<result[x].first<<" "<<result[x].second<<endl;
}
}
Answer:
The programming code can be found in the explanation part, please go through it.
Explanation:
Code:
#include<stdio.h>
#include<stdlib.h>
#include <pthread.h>
// function check whether a number
// is prime or not
int isPrime(int n)
{
// Corner case
if (n <= 1)
return 0;
// Check from 2 to n-1
for (int i = 2; i < n; i++)
if (n % i == 0)
return 0;
return 1;
}
void* printPrimes(void *vargp)
{
int *n = (int *)vargp;
int i=0;
for (i=2;i<=n;i++)
{
if (isPrime(i)) printf("%d\n", i);
}
}
// Driver Program
int main(int argc, char* argv[])
{
int n = atoi(argv[1]);
pthread_t tid;
pthread_create(&tid, NULL, printPrimes, (void *)n);
pthread_exit(NULL);
return 0;
}
Answer:
Double eleventh = 11.50;
David_Tennant = eleventh.intValue();
Explanation:
These two statements are correct. Method intValue() converts Integer to int which is is called unboxing. In this case intValue() method converting Integert part of eleventh variable then storing it in int variable David_Tennant. Output will be 11.
