若下列程序运行时输出结果为
1，A，10.1
2，B，3.5
请将程序补充完整。
#include＜iostream＞
using namespace std；
void test(int a，char b，double c)
cout＜＜a＜＜’,’＜＜b＜＜’,’＜＜c＜＜end1；
int main()
void test(int，char，double ______)；
test(1，’A’，10. 1)；
test(2，’B’)；
return 0；
参考答案：=3.5
解析： 本题考查了函数默认参数的应用。本题中第一次调用test函数数值1，A，10.1；第二次调用少了一个实参，却要求输出2，B，3.5，由此分析，应将test函数的第三个参数声明为默认参数。且默认为3.5，才能达到要求的输出结果。故应填入=3.5或者c=3.5。
