C CODING

 Escape Sequence / Execution Character Some characters such as newline, tab, backspace cannot be displayed like other normal characters. C supports the combination of backslash (\) and some characters from the C character for representing these character in our C programs. These character combinations are  known as escape sequences and are represented by two characters. The first character is "\" and second character is from the C character set. some escape sequences are given below - Escape sequence Meaning purpose \a Beep /alert Produce an audible and visible alert \b Backspace Move the cursor to the previous position of the current line. \f Form feed Moves the cursor to the initial position of the next logical page. \r Carriage return Moves the cursor to the beginning of the current line \t Tab (horizont...

Ternary operator :  we write the program first we know about ternary operator. Ternary operator are also called conditional operator (? and :) which required three expression as operands. syntax: TestExpression ? expression1 : expression2 ; If test expression is true(non-zero), then expression1 is evaluated otherwise test expression is false(zero), then expression2 is evaluated. #include <stdio.h> int main() {     int a,b;     printf( "Enter the value of a and b:\n" );     scanf( "%d%d" ,&a,&b);     // here be use a ternary operator     a>b?printf( "difference of a and b is %d" ,a-b) :printf( "Sum of a and b is %d " ,a+b);     return 0 ; } Output: Enter the value of a and b: 9 15 Sum of a and b is 24 In the above program a is less than b therefore second expression is evaluated. first it expression a>b is evaluated, it is false so the sum of the exptression2 is evaluated.
