Can anyone explain the conclusion of the outputs ?
int main() { int x=5,*p; p=&x; *p=x++ + *p; printf ("%d %d",x,*p); } We have this program now here *p= 5++ + (*p) -> *p= 5 + 5 =10 so x location is 10 and then the postfix x++= 10+1=11 so output is 11 11 ... 5 , Here x is not incrementing later . *p= x++ + 5; *p= 5+5=10 output 10 10 , when x is not taking the postfix increment ???
