Thread: Confused with the Output.....

Hi Guys. I have two programs with an Output.. Need Explanation on the Output..!!

Program 1:

Code:

void main()
{
printf("%u",main);
}

This Program print some garbage Value. But I want to know how..??? As I dont declare anything like "main" variable.

Program 2:

Code:

void main()
{
float f=1.1;
double d=1.1;
if(f==d)
 printf("I Love Java");
else
 printf("I Love C");
}

here the Output is- I Love C. here I wanna know how this Conversion is made in the memory that they are't equal..??
please Reply.

Even then, because of floating point inaccuracy, you may find that the comparison still evaluates to false.

Tried.. No change in the Output.

The moral of the story: be careful when you want to compare floating point values for equality, as what appears to be equal to you may not actually be equal, even if they are of the same type.

He could try this...

Code:

if (abs(d - (double) f) < 0.005)

Depending on allowable margin of error he should be able to adjust this to work...
