printf() and scanf() in C

In C language, input and output operations are performed by the functions printf() and scanf(), which are built-in library functions defined in the header file stdio.h.

printf() function

The printf() function prints a formatted output to the console. It can display different types of data, such as integers, characters, strings, floats, etc.

The syntax of the printf() function is:

printf("format string",argument_list);  

    The format string can be %d (integer), %c (character), %s (string), %f (float) etc.

    scanf() function

    The scanf() function is used for input. It reads the input data from the console.

    scanf("format string",argument_list);  

    Program to print cube of given number

    Let's see a simple example of c language that gets input from the user and prints the cube of the given number.

    #include<stdio.h>
    int main(){
    int number;
    printf("enter a number:");
    scanf("%d",&number);
    printf("cube of number is:%d ",number*number*number);
    return 0;
    } 

    Output

    enter a number:5
    cube of number is:125

    The scanf("%d",&number) statement reads integer number from the console and stores the given value in number variable.

    The printf("cube of number is:%d ",number*number*number) statement prints the cube of number on the console.

    Introduction To C

    Dennis Ritchie C programming is considered as the base for other programming languages, that is why it is known as mother language . Because most compilers, JVMs, kernels, etc. are written in C, and because most programming languages (such C++, Java, C#, etc.) adopt C syntax, C language is regarded as the mother tongue of all current programming languages. It offers the fundamental ideas used in numerous languages, including C++, Java, C#, and others, such as the array, strings, functions, file management, etc. C programming language  was developed in 1972 by  Dennis Ritchie  at bell laboratories of AT&T (American Telephone & Telegraph), located in the U.S.A. It was developed to overcome the problems of previous languages such as B, BCPL, etc. Initially, C language was developed to be used in UNIX operating system. It inherits many features of previous languages such as B and BCPL. Let's see the programming languages that were developed before C language. Lan

    First C Program

    Image
    Before starting the abcd of C language, you need to learn how to write, compile and run the first c program. To write the first c program, open the C console and write the following code: #include <stdio.h> :-includes the standard input output library functions. The printf() function is defined in stdio.h . int main() :-The main() function is the entry point of every program in c language. printf() :-The printf() function is used to print data on the console. return 0 :-The return 0 statement, returns execution status to the OS. The 0 value is used for successful execution and 1 for unsuccessful execution. You will see the following output on user screen.

    Compilation process in c

    Image
       What is a compilation?        C is a programming language that converts source code into object code or machine code. The conversion process has four steps: Pre-processing, Compiling, Assembling, and Linking.      The preprocessor eliminates all the comments from the source code and carries out the preprocessor directives. For instance, it substitutes the directive <stdio.h> with the contents of the 'stdio.h' file.       The following are the phases through which our program passes before being transformed into an executable form:         Preprocessor         Compiler         Assembler         Linker Preprocessor A source code file is a text file that contains instructions written in the C programming language. The file name has a ".c" extension to indicate its format. Before compiling the source code, a preprocessor analyzes and modifies it according to certain directives. The preprocessor then passes the expanded code to the compiler, which translates it in
