The following code demonstrates one way to convert from binary to octal based on user input:
#include<iostream>
#include<string>
typedef unsigned int uint;
std::string input(std::string prompt)
{
std::cout<<prompt<<": ";
std::string s;
std::getline(std::cin,s);
return(s);
}
uint input_binary( uint min, uint max )
{
uint result=0;
bool repeat=true;
while(repeat)
{
result=0;
repeat=!repeat;
std::string s=input("Enter a binary value");
for(uint i=0; i<s.size() && !repeat; ++i)
{
const char c=s.at(i);
if(c<'0'c>'1')
{
std::cout<<"Binary values may only contain characters '0' or '1'\n"<<std::endl;
repeat=!repeat;
}
result<<=1;
result|=(c-'0');
}
if(!repeat)
{
if(result<min result>max)
{
std::cout<<"The binary value must be in the decimal range "<<min<<".."<<max<<"\n"<<std::endl;
repeat=!repeat;
}
}
}
return( result );
}
int main()
{
uint binary = input_binary(0x1,0xffffff);
uint temp=binary;
uint len=1;
while(temp>>=3)
++len;
std::string octal(len, '0');
for( std::string::reverse_iterator i=octal.rbegin(); i!=octal.rend(); ++i )
{
*i=(binary & 0x7)+'0';
binary>>=3;
}
std::cout<<"Octal: "<<octal.c_str()<<"\n"<<std::endl;
return(0);
}
There is no unary plus in C, but if there were, it would have only one operand, unlike the binary plus which has two: x = a + b; /* binary plus */ x = + b; /* unary plus -- not in C*/ x = a - b; /* unary plus */ x = - b; /* unary minus */
Use an associative container such as std::set and enumerate in reverse order, or supply a predicate that sorts in descending order such as std::greater<T> (default is std::less<T>).
Use inline assembly instructions. Then compile your C++ program to produce the machine code.
The left hand operand of a binary operator must represent a modifiable lvalue: void f (const int x, int y) { x = y; // error -- x is constant lvalue y = x; // ok }
If people started writing these codes here, then what software engineers will do?
1 + 1 = 10 in binary numbers.
Because the octal number sytem is more useful for writing and clearer to read. Also, we're only using the binary system since the invention of computers which is not that long ago. Before that, there was no reason to use a binary system which is again not easy to read.
It is 1000110.
easy, 1011. in binary of course. convert 1011 binary to decimal you get 11.
1000110. In decimal, the sum is 23+47=70.
603 + 300 + 562 + 461 = 2346 (All values and total in Octal) 387 + 192 + 370 + 305 = 1254 (All values converted from octal to Decimal) 603 + 300 + 562 + 461 = 1926 (All values decimal) Octal equivalent is of the total is 3606.
Yes, the complex numbers, as well as the real numbers which are a subset of the complex numbers, form groups under addition.
If you want to add numbers in different bases, in this case decimal and binary, or do any other calculation that involves different bases for that matter, you have to convert all numbers to a single system first - for example, all to decimal. Then you can do the operation. It is really up to you in what base you represent the final answer. In this example, you can convert back to binary, for example.
Expressed in octal, the decimal sum 27 + 31 = 58 would be expressed: 33 + 37 = 72
yes it can very much so read binary.
The sum of 1,011 and 1,001 is 2,012. Unless they are binary numbers, in which case 1011 + 1001 = 10100
1 plus 1 = 2
