In this blog post, you will learn how to write a C program to trim leading and trailing white spaces from a string. How to remove both leading and trailing white space characters in a string using loop in C programming. Also, logic to delete all leading and trailing white space characters from a given

The isspace function in C programming checks whether the argument passed is a white-space character or not. The standard white-space characters are the following: space (‘ ‘ ), form feed (‘\f’ ), new-line (‘\n’ ), carriage return (‘\r’ ), horizontal tab (‘\t’ ), and vertical tab (‘\v’).   List of all standard white-space characters in C programming

The isupper function in C programming checks whether the argument passed is an uppercase letter or not. In the “C” locale uppercase letters are any of: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z. It is declared

The iscntrl function in C programming checks whether the argument passed is a control character or not. In the default, “C” locale, the control characters are the characters with the codes 0x00-0x1F and 0x7F. It is declared in ctype.h and takes one argument in the form of integer and returns the value of type int.

The isdigit function in C programming checks whether the argument passed is a decimal digit character or not. The decimal digits are any of:  0 1 2 3 4 5 6 7 8 9. It is declared in ctype.h  and takes one argument in the form of integer and returns the value of type int.

The isalpha function in C programming checks whether the argument passed is an alphabetic character (a to z and A-Z) or not. It is declared in ctype.h and takes one argument. The isalpha function tests for any character for which isupper or islower is true, or any character that is one of a locale-specific set
