printf and scanf in C

Printf() and scanf() are essential elements in C for Input and Output Operations.

Both functions utilize formatted specifiers to structure the data.

printf() 

 printf is a function in C that assists in showing information on the screen.

 It is used to Display text, Variables, and Numbers in a Specific Format.

printf( const char *format, ....);

#include<stdio.h>
int main()
{
printf("Hello, C Programming Language");
return 0;
}

Output:

Hello, C Programming Language

scanf() 

 scanf() is a function in C that allows you to get Input From User.

 It pauses until the user types something on the keyboard and then saves it in a variable for later use in the program.

 It is a Fundamental Function in C to read the Input from the user.

scanf( "format specifier", &variable); // &variable refers to memory address of variable

Format specifiers are as follows:

1'%d ' is used to read the Integer From Input.

2'%c' is used to read a Single Character from the user.

3'%f' is used to read the Floating Point Number Input.

4'%u' is used to read an Unsigned Integer from the input.

Example:

// Example of printf and scanf
#include<stdio.h>
int main()
{
int num;
printf("Enter the number:");
scanf("%d",&num);
printf("number is %d",num);
return 0;
}

Output:

Enter the number:12
number is 12
