Literals in C Language
0 342
In C programming, literals are fixed values that are directly written into the source code.
They represent fixed data values that do not change during Program Execution.
Types of Literals in C
1Integer Literals
2Floating Point Literals
3Character Literals
4String Literals
5Boolean Literals
Integer Literals
These are a Whole number of literals without any fractional part.They can be represented in different number systems.
Decimal Literals (base 10): The default format for integer literal is given as.
int decimal = 10;
Octal Literals (base 8): In C, octal literals, which are base 8 numbers, start with '0' followed by digits from 0 to 7, allowing representation of values using only these digits.
int oct=012;
Hexadecimal Literals (base 16): Hexadecimal is represented by starting with "0x" or "0X" followed by a sequence of hexadecimal digits.
Binary Literals: Binary Literals are Represented starting with 0b or 0B followed by binary digits.
int binary= 0b1010;
For example:
#include<stdio.h> int main() { int decimal =10; int oct= 012; int hex=0xA; int binary =0b1010; printf("Decimal Literal : %d\n", decimal); printf("Octal Literal : %d\n", oct); printf("Hexadecimal Literals : %d\n", hex); printf("Binary Literals : %d\n", binary); return 0; }Output:
Decimal Literal: 10 Octal Literal: 10 Hexadecimal Literal : 10 Binary Literal: 10
Floating Point Literals
Floating Point Literals in C represent numbers in fractional parts.
Floating-point literals in C allow you to express numbers with decimal points in your code.
For example:
float pi =3.14;
In C, the number '3.14' is a floating-point literal, representing the constant value of pi, which includes decimal.
#include<stdio.h> int main() { float pi=3.14; printf(" Value of pi : %f", pi); return 0; }Output:
Value of pi: 3.1400
Character Literals
Character Literal in C represents an Individual character.
In simple words, they allow you to specify a single character within your code.
For example:
#include<stdio.h> int main() { char letter = 'R'; printf("Value of letter = %c\n", letter); return 0; }Output:
Value of letter = R
String Literals
String Literals in C are a sequence of Characters enclosed within double quotes.
They represent text or string of characters.
For example:
char *message = "Hello C Programming";
using Pointer:
// Program using Pointer #include<stdio.h> int main() { char *message ="Hello C Programming"; printf("Message = %s\n", message); return 0; }Output:
Hello C ProgrammingUsing Array:
// Program using Array #include<stdio.h> int main() { char message[] ="Hello C Programming"; printf("Message = %s\n", message) return 0; }Output:
Hello C Programming
Boolean Literals
Boolean literals in C represent the two truth values: true and false.
In simple terms, they allow you to express whether something is true or false in your code.
Boolean literals in C are represented using integers value, with 0 signifying false, while any non-zero value stands for true.
For example:
#include<stdio.h> int main() { int is_hot = 1; int is_cold =0; printf("Is it hot? = %d\n",is_hot); printf("Is it cold? = %d\n",is_cold); return 0; }Output:
Is it hot? = 1Is it cold? = 0
