C++ Char Data Types
Last Updated :

A Char datatype is a datatype that is used to store a single character. It is always enclosed within a single quote (‘ ‘).
Syntax:
Char variable;
Example:
C++
#include <iostream>
using namespace std;
int main()
{
char c = 'g';
cout << c;
return 0;
}
|
ASCII Value
ASCII Value stands for American Standard Code for Information Interchange. It is used to represent the numeric value of all the characters.
ASCII Range of ‘a’ to ‘z’ = 97-122
ASCII Range of ‘A’ to ‘Z’ = 65-90
ASCII Range of ‘0’ to ‘9’ = 48-57
To know more about it, refer to the article – ASCII table.
Convert Character Value to Corresponding ASCII Value
To convert a character to ASCII value we have to typecast it using int(character) to get the corresponding numeric value.
Example:
C++
#include <iostream>
using namespace std;
int main()
{
char c = 'g';
cout << "The Corresponding ASCII value of 'g' : ";
cout << int(c) << endl;
c = 'A';
cout << "The Corresponding ASCII value of 'A' : ";
cout << int(c) << endl;
return 0;
}
|
Output
The Corresponding ASCII value of 'g' : 103
The Corresponding ASCII value of 'A' : 65
Convert ASCII Value to Corresponding Character Value
To convert an ASCII value to a corresponding Character value we have to typecast it using char(int) to get the corresponding character value.
Example:
C++
#include <iostream>
using namespace std;
int main()
{
int x = 53;
cout << "The Corresponding character value of x is : ";
cout << char(x) << endl;
x = 65;
cout << "The Corresponding character value of x is : ";
cout << char(x) << endl;
x = 97;
cout << "The Corresponding character value of x is : ";
cout << char(x) << endl;
return 0;
}
|
Output
The Corresponding character value of x is : 5
The Corresponding character value of x is : A
The Corresponding character value of x is : a
Escape Sequence in C++
Escape sequences are characters that determine how the line should be printed on the output window. The escape sequence always begins with a backslash ‘\’ (also known as an escape character). Some Examples of Escape Sequences are mentioned below:
| S. No. |
Escape Sequences |
Character |
| 1. |
\n |
Newline |
| 2. |
\\ |
Backslash |
| 3. |
\t |
Horizontal Tab |
| 4. |
\v |
Vertical Tab |
| 5. |
\0 |
Null Character |
Example:
C++
#include <iostream>
using namespace std;
int main()
{
char a = 'G';
char b = '\t';
char c = 'F';
char d = '\t';
char e = 'G';
char f = '\n';
string s = "is the best";
cout << a << b << c << d << e << f << s;
return 0;
}
