HOW TO USE PRINTF IN C HOW TO

the address operator is prefixed to the variable roll. The above statement declares the variable roll of type int and reads the value of roll from the keyboard.

Similar to printf() function scanf() function also uses the %d %f %c and other format specifiers to specify the kind of data to be from the keyboard.

How to read data from the keyboard using scanf() function: Then, the user enters a string and this value is assigned to the variable вЂњstrвЂќ and then displayed. This value is assigned to the variable вЂњchвЂќ and then displayed. Scanf() function is used to read character, string, numeric data from keyboardД¬onsider below example program where the user enters a character. It may be further noted that both messages and format specifier can be included within the pair quotes as shown below printf(вЂњthe age of student=%dвЂќ, age) the above statement displays the following of students on the screen. a format specifier written within quotes and the variable age. It may be noted that printf() has 2 arguments separated by comma i.e. The data is stored in a variable called age. Initialize age to 25 as an integer value specify %d a format specifier indicating that an integer is to be displayed by printf(). How to display data using printf() function:-ДЄn integer stored in a variable can be displayed on the screen by including a format specifier (%d) within a pair of quotes as shown below. To generate a newline, we use вЂњ вЂќ in the C printf() statement. Similarly, %c is used to display character, %f for float variable, %s for a string variable, %f for double and %x hexadecimal variable. We use printf() function with a %d format specifier to display the value of an integer variable. Printf() function is used to print the вЂњcharacterвЂќ, string, float, integer, octal, and hexadecimal values onto the output screen. We have to include вЂњstdio.hвЂќ file to make use of this printf() and scanf() library functions.Д¬ users these functions to write and read from I/O devices respectively. A great thing about the printf formatting syntax is that the format specifiers you can use are very similar if not identical between different languages, including C, C++, Java, Perl, PHP, Ruby, Scala, and others. I originally created this cheat sheet for my own purposes, and then thought I would share it here. These functions are declared and related macros are defined in вЂњstdio.hвЂќ which is a header file. Summary: This page is a printf formatting cheat sheet. printf() and scanf() functions are inbuilt library functions in C which are available in C library by default.
