std:：log

是基数e对数函数。至于你的另一个问题，在我看来，你想要（int y=1；y）为1

#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;

int main(){


//Numbers 1 - 10
cout << "Number" ;
for (int i = 1; i <= 10; i++) {
    cout << "\n" << i  ;
}//end for
cout << endl;



//log base 2
cout << "\n" << "Log base 2" << "\n";
for(int x = 1; x <= 10; x++){
cout<<log2(x)<<endl;
}//end for



//log base 10
cout << "\n" << " Log base 10 " << "\n" ;
for ( int y = 1; y <= 10; y++){
cout<<log10(y)<<endl;
}//end for


cout << "Log base e";
for (int z = 1; z <=10 ; z++){



}
}//end main

#include <iostream>
