c problem

[arpanmukherjee1]

hello

i want to know how the Turbo cpp (yes, the dinosaur one) and g++ give different output:

a=10
++a + ++a = 24 (g++)  & 23 (TC)
a++ + a++ = 20
++a - a++ = 0 (g++) & -1(TC)

please explain pre and post increment and decrement in this prgs.

also please tell how to obtain output of such prgs

one more thing -> if in expression pre and post increment occure together what is the precedence order??

uz gcc there you cn pass commandd:

gcc -S filename.c

you cn alsoo see the output in the filename.s file. it shows assembler o/p wcih teh compiler generates and then links

i dnt knw howw tc generates the code bt itz 4 nuuub neway
