@Akshay.
Just use like Logical Operators (float)4.2==(float)4.2 is equal, so that's true and prints 1, as float, 1.0000000.

Very good example given by all of you. Thanks for your time.

I do not exactly. But I think this concept follows partial initialization, full initialization, null initialization. If I'm wrong any explain me the concept.

How the output came like this?

#include<stdio.h>
int main(){
float x;
x=(float)4.2==(float)4.2;
printf("%f",x);
x=(float)3.5==3.5;
printf("\n%f",x);
return 0;
}
Answer:
1.00
1.00
This one works. I just converted both no into float.
I just cannot figure out exactly why this is happening. Hope someone can figure out.
int main(){
float x;
x=(float)4.2==(float)4.2;
printf("%f",x);
x=(float)3.5==3.5;
printf("\n%f",x);
return 0;
}

Can you explain the difference between float, double and long double?

Could you explain me what is deference between double and long double real data type?
Ajay said:

float, double and long double called real data type because it's compute real value of any number. For Example if we want to get accurate output suppose A = 2.3 and B = 3.2 and C, Thus, C = A +B;
We get 5.500000; Hence its called a real data type.
