c++ - Shouldn't be this "=+" a syntax error? -


recently trying use following code:

int number = 4; number += other_variable;//2 ... printf("number:%d\n",number);//-->6

but had error typing , instead i've got code:

int number = 4; number =+ other_variable;//2 ... printf("number:%d\n",number);//-->2

apparently compiled gcc 4.7.3 , gcc 4.4.3 , result normal assignment operator. question is: shouldn't syntax error?

no - being parsed as:

number = +other_variable;

i.e. have assignment , unary + operator. you're reading =+ it's 2 separate operators, = , +.
