c - sizeof operator returning different output. why? -


this question has answer here:

while using sizeof operator , sizeof (0.7) printed 8 , storing same number floating point variable a = 0.7 , using sizeof(a) printed 4. why so?

size of not function, , eveluated during compilation.

sizeof 0.7 gives size of double constant double

sizeof 0.7f gives size of float f @ , informs compiler constant float

your variable a float , assignment converts double constant float

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
