Int b 0 static int c 3

Nettetint a = 7; int b = 3; double c = 0; c = a / b; c ends up having the value 2, rather than 2.3333, as one would expect. If a and b are doubles, the answer does turn to 2.333. But surely because c already is a double it should have worked with integers? So how come int/int=double doesn't work? c++ variables double integer-division Share Nettet24. jul. 2012 · c为静态变量，静态变量的特点是函数前一次被调用产生的结果被保留下来，在下一次被调用时仍然有效。 b为自动变量，函数的每次被调用，都是重新分配内存。 所以： 第一次调用f (a)返回的是 7 （2+1+4） 第二次调用f (a)返回的是 8 （2+1+5） 第三次调用f (a)返回的是 9 （2+1+6） 4 评论 分享 举报 2015-06-01 main () {int f (int); int …
