C Format Specifiers

---

In C programming, a format specifier is a special character that is used to specify the type of data that will be printed or read in a formatted input/output operation.

Format specifiers are used in conjunction with the printf() and scanf() functions to format the input and output of data.

Here are some commonly used format specifiers in C:

Type	Format Specifier
int	%d, %i
char	%c
float	%f
double	%lf
short int	%hd
unsigned int	%u
long int	%ld, %li
long long int	%lld, %lli
unsigned long int	%lu
unsigned long long int	%llu
signed char	%c
unsigned char	%c
long double	%Lf

printf() example:

int a = 10; 
float b = 3.14;
 
printf("The value of a is %d and the value of b is %f", a, b);`

In this code, the format specifiers %d and %f are used to print the integer and floating-point values of a and b, respectively.

scanf() example:

   int age;
   char name[20];
   
   printf("Enter your age: ");
   scanf("%d", &age); // using %d format specifier to read integer input
