The fabs function in C computes the absolute value of a floating-point number x. The x is the argument that is passed into the fabs(). It is declared in math.h and takes one argument in the form of double and returns the value of type double. Example, Input : 3.5 Output : 3.5…
The floor function in C computes the largest integer value not greater than x. In other words, you can say that the floor function computes the largest integer value not greater than x. The x is the argument that is passed into the floor(). It is declared in math.h and takes one argument…
The ceil function in C computes the smallest integer value not less than x. In another word, you can say that ceil function computes the smallest integer that is greater than or equal to x. The x is the argument that is passed in the ceil(). It is declared in math.h…
The pow function in C computes x raised to the power y (xy). A domain error occurs if x is finite and negative and y is finite and not an integer value. A domain error may occur if x is zero and y is zero. A range error occurs if…
The sqrt function in C computes the nonnegative square root of x (sqrt parameters). A domain error occurs if the argument is less than zero. It is declared in math.h and takes one argument in the form of double and returns the value of type double. Syntax of sqrt function…
The isgraph function in C programming checks whether a character is a graphic character or not. The character that has graphical representation are known are a graphic character. It is declared in ctype.h and takes one argument in the form of integer and returns the value of type int. If the…
The isxdigit function in C programming checks whether the argument passed is a hexadecimal-digit character or not. Hexadecimal digits are any of: 0 1 2 3 4 5 6 7 8 9 a b c d e f A B C D E F. It is declared in ctype.h and takes…
The isprint function in C programming checks whether a character is a printable character or not. The printable character could be alphanumeric numbers (0 to 9, A to Z, or a to z), a punctuation character(!”#$%&'()*+,-./:;<=>?@[\]^_`{|}~), or space ( ‘ ‘), or any character classified as printable by the current C…
The ispunct function in C programming checks whether a character is a punctuation character or not. The default C locale classifies the characters !”#$%&'()*+,-./:;<=>?@[\]^_`{|}~ as punctuation. It is declared in ctype.h and takes one argument in the form of integer and returns the value of type int. If the character…
The toupper function C programming converts a lowercase letter to a corresponding uppercase letter. In the default “C” locale, a lowercase letter is 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….
