if a is int then ans will be bye but here ans will be hi bez a is of type float. You can check by compiling program. or print this line ::: printf("%.5f %.5f ", 0.7 ,0.7f); you will find difference.

out put for:: printf("%.5f %.5f ", 0.7 ,0.7f); 0.77777 0.69999 for float it read as 0.69999 and for double 0.77777 so at (a<0.7)// it will compare (0.69<0.7 ) which is true so it will give o/p" hi". You can check this code. I hope you guys find this information interesting.

ans is "hi" because a = 0.7 but since it is float it will be read as 0.69

probably "bye" because a is something like 0.70000001. comparing floats is dangerous because floats rarely are completely accurate. read more about floats and how to compare them: https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/
