想了解C++ 怎样用cout输出hex,oct,dec的解决办法的相关内容吗，在本文为您仔细讲解cout输出hex oct dec的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：hex,oct,dec，下面大家一起来学习吧。
HEX:
#include <iostream.h>
#include <iomanip.H>
main(void)
{
long n = 10000;
cout << hex << n ;
return 0;
}
OCT:
#include <iostream.h>
#include <iomanip.H>
main(void)
{
long n = 10000;
cout << oct << n ;
return 0;
}
DEC:
#include <iostream.h>
#include <iomanip.H>
main(void)
{
long n = 10000;
cout << dec << n << endl;
return 0;
}
#include <iostream>
using namespace std;
int main()
{
cout.setf(ios::hex, ios::basefield);
cout << 100; // this displays 64
return 0;
}
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
int n;
cout << "Enter a decimal number: ";
cin >> n;
cout << n << " in hexadecimal is: "
<< hex << n << '/n'
<< dec << n << " in octal is: "
<< oct << n << '/n'
<< setbase( 10 ) << n << " in decimal is: "
<< n << endl;
return 0;
}
