Not solve, % lf; But to float n; Can assignment that is eight,

 
#include  
#include  

using namespace std; 

Int main () 
{double n; 
The scanf (" % f ", & amp; n); 
Printf (" % f ", n); 

return 0; 
} 

CodePudding user response:

Lf the scanf (" % ", & amp; n); Lf not line? Long float

CodePudding user response:

Lf the scanf (" % ", & amp; n); Should ok,

CodePudding user response:

I can't, the scanf (" % lf ", & amp; n); I tried just cannot copy; I create the CPP file

CodePudding user response:

Unable to assignment

CodePudding user response:

Try the le or lg,

CodePudding user response:

Using the scanf (" % lg ", & amp; n); Or use the scanf (" % le ", & amp; n); Can be assigned;
But the output of the printf must use % f
Why???????
It is ok. C document! So why not CPP?

CodePudding user response:

Verified, the scanf (" % lf ", & amp; n); Yes, vc + + (2010 and 2013), BCC, 6.70 GCC 4.7.0 can,

CodePudding user response:

Your codeblock use is what the compiler, that version?
