Please tell me guys how to work pre-increment operator and tell me how to come here 15,66 result.

#include <studio.h> int main() { int a,b; a=10; b=(++a)+(++a)+(++a)+(++a)+(++a); printf ("A nd B is=%d %d",a,b); return 0; }

actually it should be 15,65 in my opinion. you have a=10 in start, but every ++a operation increments it’s value to one integer more, so ++a equal 11, next +a equal 12 and finally, because you have did this operation five times, your a equals 15. incouding this knowing, you will be count b as 11+12+13+14+15 (because every ++a opeartion is returning a as one integer higher value). so now b equals 65 (because in the start you didn’t set this value, so it was zero). notation „%d” takes the next argument and prints it as a int. so a and b will be print as a int. now you get 15,65
