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.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);double data type format in c
%lf you can tryformat specifiers in c
