How to take values in c++

Answer 1

You can use cin from the <iostream> library.

#include <iostream>
#include <string>

using namespace std;

int main()
{
string x;
cin >> x;
}

It works for all standard data types (int, float, double, string, char,...).
However, if you want to read a string, cin will stop reading when it reaches a whitespace:
Entering "a b" in the program above will result in x = "a".

If you want to read an entire line with whitespaces into a variable, replace the last line with this:
getline(cin, x);

I think those are the most popular ways for reading values from user input.

Answer 2

for example,
int a;
cout<<"Please enter a number"<<endl;
cin>>a;

Answer 3

use 'cin':

#include <iostream>

using namespace std;

int main(){
int number = 0;
cout << insert a number;
cin >> number;
cout << you inserted << number << endl;
return 0;

}
