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 4: printf format specifiers 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; } Characters: a A Decimals: 1977 650000 Preceding with blanks: 1977 Preceding with zeros: 0000001977 Some different radices: 100 64 144 0x64 0144 floats: 3.14 +3e+000 3.141600E+000 Width trick: 10 A string
