I wanna know the best explanation of the output of this code

Question

#include<stdio.h>
int main()
{
float a=0.9;

if(a==0.9)
printf("Hello");
else
printf("World") ;
return 0;
}

Answer 1

It's because of float accuracy. In fact a is not 0.9 but 0.89..... (look in the code).Just declare "a" as double which has more accuracy and you'll achieve what you want. Hope it helps you 😉
