本篇文章是对C++中如何用cout输出hex,oct,dec的方法进行了详细的分析介绍,需要的朋友参考下
HEX:
代码如下:
#include
#include
main(void)
{
long n = 10000;
cout << hex << n ;
return 0;
}
#include
main(void)
{
long n = 10000;
cout << hex << n ;
return 0;
}
OCT:
代码如下:
#include
#include
main(void)
{
long n = 10000;
cout << oct << n ;
return 0;
}
#include
main(void)
{
long n = 10000;
cout << oct << n ;
return 0;
}
DEC:

代码如下:
#include
#include
main(void)
{
long n = 10000;
cout << dec << n << endl;
return 0;
}
#include
main(void)
{
long n = 10000;
cout << dec << n << endl;
return 0;
}
代码如下:
#include
using namespace std;
using namespace std;
int main()
{
cout.setf(ios::hex, ios::basefield);
cout << 100; // this displays 64
return 0;
}
代码如下:
#include
#include
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;
}
#include
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;
}
