can any one explain plz urgently

code was this
#include<stdio. h>
#include<conio. h>
void main()
{

double a=3.1428571;
int b=4347;
printf("%e\t%5d \t%5.4f\t%.5f\n ",a,b,9,9);
getch();
}


--------OUTPUT-------------
3.142857e+000 4347 0.0000 0.00000
plz explain this why is the output of this function is this

if you select %e formatted that means you wanna print that floating point numbers format that save memory because of floating points.
3.142857e+000 that output means there isn't any sliding point i mean that if there is written -01 after 'e' the real number would be occur when you slide the point one time to left the following example will make clear
3.142857e+000=0 .3142857e-01
if the operator is '+' you need slide the dot right written times(after e)

the following wrong is that
printf("%e\t%5d \t%5.4f\t%.5f\n ",a,b,9,9);
i am not sure but i think the problem is that you wrote a number that in order to object...

it is all related to the format specifiers you are giving in the printf string, these are

%e
%5d
%5.4f
%.5f

and you pass in for these specifiers

double a=3.1428571;
int b=4347;
integer constant 9
integer constant 9

respectively. Taking the triples (format string, value, output)

3.142857e+000, %e, double a=3.1428571;

a is a floating point variable of type double with the value 3.1428571, %e indicates the printf to expect a floating point value and to print it out in exponential format therefore printf outputs 3.142857e+000

4347, %5d, int b=4347;

b is and integer variable with the value 4347, %5d indicates to printf to expect an int and to output it in a field of size 5 (i.e. 5 characters wide), therefore printf outputs ' 4347'.

0.0000, %5.4f, integer constant 9

integer constant 9 is an integer constant value 9, unfortunately %5.4f indicates to printf to expect a double value since int is normally 2 or 4 bytes and double is 8 bytes printf f consumes both the first and second integer constant 9 and interprets them as a double (this appears to have value 0 or alternatively is not representable) there printf outputs '0.0000' note it has followed the specification of 4 decimal places but ignore the specification of field with 5, it is impossible to fit 4 decimal places into a field width of 5.

0.00000, %.5f, integer constant 9

actually this integer constant has already been consumed by printf, at this point it is just reading random stack data it is just sheer fluke that the value is 0. %.5f indicates to printf to expect a double and print it using 5 decimal places so it outputs 0.00000
