long format specifier in c code example

Example 1: format specifier fro float in printf

printf("%0k.yf" float_variable_name)

Here k is the total number of characters you want to get printed. k = x + 1 + y (+ 1 for the dot) and float_variable_name is the float variable that you want to get printed.

Suppose you want to print x digits before the decimal point and y digits after it. Now, if the number of digits before float_variable_name is less than x, then it will automatically prepend that many zeroes before it.

Example 2: what are format specifiers

it is used during taking input and out put

Int ("%d"): 
Long ("%ld"):
Char ("%c"): 
Float ("%f"): 
Double ("%lf")

example:

char ch = 'd';
double d = 234.432;
printf("%c %lf", ch, d);

char ch;
double d;
scanf("%c %lf", &ch, &d);

Example 3: double data type format in c

%lf you can try

Example 5: printf format specifiers c

/* printf example in C */
#include <stdio.h>

int main()
{
   printf ("Characters: %c %c \n", 'a', 65);
   printf ("Decimals: %d %ld\n", 1977, 650000L);
   printf ("Preceding with blanks: %10d \n", 1977);
   printf ("Preceding with zeros: %010d \n", 1977);
   printf ("Some different radices: %d %x %o %#x %#o \n", 100, 100, 100, 100, 100);
   printf ("floats: %4.2f %+.0e %E \n", 3.1416, 3.1416, 3.1416);
   printf ("Width trick: %*d \n", 5, 10);
   printf ("%s \n", "A string");
  
   return 0;
}
