math - Issue with % operator in C -

i having issue % operator in c. know % operator gives remainder of division. when faced question 1 % 2 or 3 % 2, confused. after googling this, found different solutions.

some 1 / 2 0.5, round down 0. 1 % 2 0.

others 1 / 2 0.5, instead round up, in maths, 1. 1 % 2 1.

and therefore, confused. question is: what 1 % 2?

thank in advance :):)

simply put, both wrong methods. said % finds remainder of division.

therefore 1/2 equal 0 remainder 1.

and answer 1.

also, experiment yourself, have used program:

#include <stdio.h>  main() {     int remainder;      remainder = 1 % 2;     printf("1 %% 2 %d", remainder);     return(0); } 

hope helps :)
