Floating Point Issues

Q1:

What will be the output of the program? 
#include<stdio.h>
int main()
{
    float f=43.20;
    printf('%e, ', f);
    printf('%f, ', f);
    printf('%g', f);
    return 0;
}

A 4.320000e+01, 43.200001, 43.2

B 4.3, 43.22, 43.21

C 4.3e, 43.20f, 43.00

D Error

ANS:A - 4.320000e+01, 43.200001, 43.2

printf('%e, ', f); Here '%e' specifies the 'Scientific Notation' format. So, it prints the 43.20 as 4.320000e+01. printf('%f, ', f); Here '%f' specifies the 'Decimal Floating Point' format. So, it prints the 43.20 as 43.200001. printf('%g, ', f); Here '%g' 'Use the shorter of %e or %f'. So, it prints the 43.20 as 43.2.
