Character Operations

Thu Nov 13, 2008 2:19 pm

Characters in C are really just small integers, applying characters operations on C++
cpp code

char ch; 	
scanf("%c", &ch); 	Read the next character
ch = getchar(); 	Read the next character (plain C)
cin.get(ch) 	Read the next character
scanf(" %c", &ch); 	Read the next non-blank character
cin >> ch 	Read the next non-blank character
printf("%c", ch); 	Print a character
putchar(ch); 	Print a character (plain C)
cout << ch 	Print a character
ch + 5 	Arithmetic on chars is okay.
ch - 'a' + 'A' 	Change case
#include <ctype.h> 	
#include <cctype> 	
isalpha(ch) 	
isupper(ch) 	
. . . 	
toupper(ch) 	
toascii(ch)
