TRICKS OF C LANGUAGE

Tricks of C language

1.     ‘ \t ’ :- It will leave 7 or 8 spaces (Tab)

Example:

   printf(“ Tricks of \t C language”);

Output: Trics of                  C language

2.     ‘ \r ‘ :- return the whole line

Example:

 printf(“ This is \r”);

 printf(“ C language”);

Output: C language

3.     ‘ \r\n ‘ :- same as \n

Example:

   printf(“ This is \r\n C languge”);

 Output: This is

                   C language

4.     ‘ \a ‘ :- this will give a beep

Example:

 printf(“ \a”);

Output: (it will a beep sound)

5.     To print

                        “ hey i’m learning c language”

printf(“\ “ Hey i’m learning c\””);

6.     int a=5.5;

printf(“a = %d”, a);

Output:   a=0

7.     char ch=’A’;

printf(“ch = %d”, ch);

Output: ch=65

8.     ASCII values

Digits (0 – 9) : 48 to 57

A – Z : 65 to 90 ( capital letters)

 a – z :  97 to 122 ( small letters)

·        To print value of double type use “ %f “ as a formate specifier.

Example :

double a=5.557;    

printf(“ double = %f ”, a);

Output: double = 5.557

·        The range of unsigned char is 0 to 255. If you store a number that is outside this range, the number is divided by 256 and remainder is stored in the variable.

·        Range of signed char is -128 to 127. If we store a number that is 1 more than 127 i.e. 128, the number stored will be -128, for 129 it will be -127 and so on. If you store -129 output will be 127.

·        The range of all data types ( int, char, float, double with qualifiers i.e. signed, unsigned) is stored in header file < limits.h>.

·        For to get remainder use “ % “ operator.

·        In order to print % on the output screen use % twice.

Example:

printf(“ C language is 100%% good language”);
