Question: (numeric_limits & lt; Char> : : min) () function cannot show subsequent text, such as

Source:

 # include & lt; Iostream> 
using namespace std; 

//variable declaration 
Extern int a, b; 
Extern int c; 
Extern float f; 

Int main () 
{
//variable definition 
int a, b; 
Int c; 
Float f; 

//actual initialization 
a=10; 
B=20. 
C=a + b; 

Cout & lt; 
F=70.0/3.0; 
Cout & lt; 
return 0; 
} 

Results:


Obviously wrong,
I commented out the code below can show the back of the results,

//cout & lt; <"Char: t \ \ t" & lt; <"The number of bytes:" & lt; //cout & lt; <"\ t Max:" & lt; <(numeric_limits & lt; Char> : : Max ());//(numeric_limits & lt; Char> : : min) (the) can't use the 
//cout & lt; <"T \ \ t the minimum:" & lt; <(numeric_limits & lt; Char> : : min) () & lt; //cout & lt; <"Signed char: \ t" & lt; <"The number of bytes:" & lt; //cout & lt; <"\ t Max:" & lt; <(numeric_limits & lt; Signed char> : : Max ()); 
//cout & lt; <"T \ \ t the minimum:" & lt; <(numeric_limits & lt; Signed char> : : min) () & lt; //cout & lt; //cout & lt; <"\ t Max:" & lt; <(numeric_limits & lt; Unsigned char> : : Max ()); 
//cout & lt; <"T \ \ t the minimum:" & lt; <(numeric_limits & lt; Unsigned char> : : min) () & lt;  
Find the & lt; Limits> Header file, inside of char function is defined, how is this to return a responsibility excuse me?
 CodePudding user response: 
Didn't understand what you ask?????? 
The first piece of code behind and what is the connection?????? 
Unsigned char biggest sure to print out,
 CodePudding user response: 
Bad, head dizzy, thanks to "the truth is right and wrong" reminds, code duplication is wrong, the first piece of code should be below code,

# include & lt; Limits>
