Why print else part not if part any one knows answer tell me

Question

void main()

{

float a=1.1;

if (a==1.1)

printf("santosh");

else

printf("find reason");

getch();

}

Answer 1

The issue is that you are trying to compare to floats for equality. It is likely that a floating point precision error occurs:

Answer 2

If a fractional number is written without the f suffix, then it is a double type precision, so you are trying to compare two different precision classes, which naturally gives false.

Debug:
float a=1.1;
if (a==1.1f) printf("santosh");

Answer 3

// Try it

if (a==(float)1.1)
