.h C Programming

H files are called header files they should not contain any code unless it happens to contain information about a C templated object. Computing the square root squareRoot sqrtnumber.

PrintfSquare root of 2lf 2lf number squareRoot.

.h c programming. Some of its most commonly used functions are clrscr getch getche kbhit etc. C sqrt Function. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system.

C is the most widely used computer language. The C library function double ceil double x returns the smallest integer value greater than. Colors in C Graphics Programming There are 16 colors declared in graphicsh header file.

All the functions available in this library take double as an argument and return double as the result. Enter the value of x to find ex. C programming is a general-purpose procedural imperative computer programming language developed in 1972 by Dennis M.

Include include int main double number squareRoot. Let us discuss some important functions one by one. C files are the source files.

We use colors to set the current drawing color change the color of background change the color of text to color a closed shape etc Foreground and Background Color. They typically contain function prototypes typedefs define statements that are used by the source files that include them. Double ceil double x.

The mathh header defines various mathematical functions and one macro. The timeh header defines four variable types two macro and various functions for manipulating date and time. PrintfExponential of 2lf 2lf x result.

C exp function include include int main double x 120 result. The conioh header file used in C programming language contains functions for console inputoutput. 12 Exponential of 1200 16275479.

Following are the variable types defined in the header timeh. For example the program PizzaDelivery could have 1 c file with the main program and 1 c file with utility functions. The h files are used to expose the API of a program to either other part of that program or other program is you are creating a library.
