Write a C Program To read text file and print it on screen using File Handling. Here’s simple Program To read text file and print it on screen using File Handling in C Programming Language. Below is the source code for C Program To read text file and print it on screen using File Handling which is successfully compiled and run on Windows. A simple C program to display 'Hello, World!' On the screen. The stdio.h file contains functions such as scanf() and print() to take input. C++ tutorial-print text on the screen Printing text on the screen The cout command can be used to print the values of variables on the screen. If you want to print a string value, you need to place the string value in dobule quotes. To print a variable, you won't need to place the variable in double or single quotes. You can print many values or variables with a single cout statement. ![]() Each value or variable must be preceeded by the > Downloadable games for mac computer. sign. Example: char *s; cout > s; Constant Variable A constant variable is a variable whose value cannot be changed later by the code in the program. The value of a constant must always be set when it is declared. There are two ways to declare a constant in C++ language. The first is to use const keyword before the variable. Example: const PI = 3.14; The second way is to use #define to create a constant. Example: #define PI 3.14. Welcome to C! Windows media player for mac uk. Comments This program illustrates several important C features. Lines 1 and 2 // Fig. 2.1: fig02_01.c // A first program in C begin with //, indicating that these two lines are comments. Comments do not cause the computer to perform any action when the program is run. Comments are ignored by the C compiler and do not cause any machine-language object code to be generated. The preceding comment simply describes the figure number, file name and purpose of the program. You can also use /*. */ multiline comments in which everything from /* on the first line to */ at the end of the last line is a comment. ![]() We prefer // comments because they’re shorter and they eliminate common programming errors that occur with /*. */ comments, especially when the closing */ is omitted. #include Preprocessor Directive Line 3 #include is a directive to the C preprocessor. Lines beginning with # are processed by the preprocessor before compilation. Line 3 tells the preprocessor to include the contents of the standard input/output header ( ) in the program. This header contains information used by the compiler when compiling calls to standard input/output library functions such as printf (line 8). We explain the contents of headers in more detail in Chapter 5. Blank Lines and White Space Line 4 is simply a blank line. You use blank lines, space characters and tab characters (i.e., “tabs”) to make programs easier to read. Together, these characters are known as white space.
