Hello guys, what’s up? I have found that many of you searching about what is %c for? So, today I am going to discuss about it. Let’s start—
%c is the format specifier used for getting character or char data type. %c interprets it’s as a character value for display. 

Syntax:

printf("%c",<variable name>);  //for print
scanf("%c",<variable name>); //for reading data from users

When we use %c in printf(), there we want a single character for output.

#include <stdio.h> 
int main() 
{ 
 char ch = 'A'; 
 printf("%cn", ch); 
 return 0; 
}

When we use %c in scanf(),  there we want a single character (a-z or, A-Z) from user, not a word nor a number.

#include <stdio.h> 
int main() 
{ 
 char ch; 
 scanf("%c", &ch); // input is A 
 printf("%cn", ch); 
 return 0; 
}

Output: A

Example: print 97 (on an ASCII system) [A-65,… a=97]

#include <stdio.h> 
int main() 
{ 
  printf("%c",97);
 return 0; 
}

Output: a

Today we learn  what is %c for. I hope you guys understand everything which I have discussed earlier. So guys, that’s all for today. Later we will discuss another tutorial on c programming. Till then, take care. Happy Coding
