What are Backslash character constants in C language?
A backslash ( \ ) that allows a visual representation of some nongraphic characters introduces an escape.
One of the common escape constants is the newline character ( \n ).
Backslash Characters
The backslash characters are as follows −
| Character | Meaning |
|---|---|
| ‘\a’ | alert |
| ‘\b’ | backspace |
| ‘\f’ | form feed |
| ‘\n’ | newline |
| ‘\t’ | horizontal tab |
| ‘\r’ | carriage return |
| ‘\v’ | vertical tab |
| ‘\\’ | backslash |
| ‘\’ ’ | single quote |
| ‘\" ’ | double quote |
| ‘\?’ | Question mark |
Example program
Following is the C program for the backslash character constants −
Example
#include<stdio.h>
#define PI 3.14
float area;
void main(){
double r;
r=1.0;
area = PI * r * r;
printf("Area is %d \n", area); // /n is used to enter the next statement in newline
}Output
Area is 1492442840
