Can go language like c language implementation letters and ASCII swap?
If you can how to swap?
Like a string (80) can get P
But the letter how to convert the ASCII code?

S:=string (80) 
//string can only first array, and then according to the length of the array in each element 
Arr=(byte []) (s) 
Num:=arr [0] 

CodePudding user response:

 
S:='P' 
B:=(byte) (s) 
FMT. Println (b) 

CodePudding user response:

Please use the for range string try

CodePudding user response:

You can use a rune types, the code is as follows:

 
Var a rune='P' 

FMT. Println (" a: ", a) 
FMT. Println (" a: ", string (a)) 
FMT. Println (" a: ", string (80)) 

Results:
A: 80
A: P
A: P

Single letter can use strconv. Atoi
String can use byte [] (STR)

P:=FMT. Sprintf (" % c ", 80)
