第二题呀，我不知道我错在哪里了#include <stdio.h>int even(int n);int main() { int n; int sum = 0; printf("输入一批正整数:\n"); while (n >= 0) { scanf("%d", &n); if (n <= 0) break; if (even(n) == 0) { sum += n; } } printf("奇数和为%d\n", sum); return 0;}int even(int n) { int number; if (n % 2) number = 0; else number = 1; return number;}
