In this tutorial, we are going to discuss unformatted output functions used to display the output to the user at the console. These output values could be of any primitive data type or an array type. Some of the most important unformatted console output functions are -

Unformatted Console Output Functions	Description
puts()	Displays a single string's value at the console.
putch()	Displays a single character value at the console.
putchar()	Displays a single character value at the console.








Why the functions are called unformatted console output functions?


While calling any of the unformatted console output functions, we do not have to use any format specifiers in them, to display a value on the console. Hence, these functions are named unformatted console output functions.






• Using puts() to display the content of string




/* Using puts() function to display a string*/ 

#include<stdio.h>

int main()
{
char country[20];
printf("Enter a country you want to visit : ");
gets(country);
printf("The country you want to visit is : ");
puts(country);

return 0;
}




Output




Enter a country you want to visit : New Zealand
The country you want to visit is :  New Zealand



The function puts() is used to display the content of a char array/string. Just like gets() function, the the puts() method does not take any format specifier as a parameter but only takes the name of char array whose content is to be displayed.

• Using putch() and putchar() to display the a char value


In the upcoming example, we are going to use two unformatted console output functions putch() and putchar, to display a char value.



#include<stdio.h>
#include<conio.h>

int main()
{
int ch = 'a';

printf("The character value printed using putch() : ");
putch(ch);

printf("\n");
printf("Another character value printed using putch() : ")
putch('B')

printf("\n");
printf("The character value printed using putchar() : ");
putchar(ch);

printf("\n");
printf("Another character value printed using putchar() : ")
putch('D');

return 0;
}





Output




The character value printed using putch() :a
Another character value printed using putch() : B
The character value printed using putchar() : a
Another character value printed using putchar() : D



As you may see in the code, we can call putch() and putchar() functions to display a character by passing a char variable or by passing a character value directly to it.
