Why this code is printing Hi?

Question

It is printing Hi
How it come?
#include<stdio.h>
int main()
{
float a = 0.7;
if(a < 0.7)
printf("Hi");
else
printf("hellow") ;
return 0;
}

Answer 1

Try to use the literal f at the end of the number. Good practice.
Example:. a=0.7f;

Also in the comparation if (a<0.7f)

If you don't use it the compiler will promote a as double when evaluate the conditional expression. Better use f literal with float numbers.

Yeh that's working with double,
But why float is not working?
