6、oid fp(char)；( f ) int fp(char，int)；( f ) void fp(char，int，int)；( t )5要使语句p1=new long * ；p2=new float * 15；能正常执行，写出p1和p2的定义。long * p1； float * p2；四、（每题10分，共20分）1写出下列程序的执行结果。 # include void fun(int，int，int * )； void main() int x，y，z； fun (2，3，&x)； fun (4，x，&y)； fun (x，y，&z)； coutx,y,zendl； void fun(i

7、nt a，int b，int * c ) b*=a；*c=b-a； 4，12，442下列程序向a盘上的文本文件aaa.dat输出0至100间的整数，请将程序补充完全。 # include # include _ void main(void) ofstream f1(void main() )； if (_!f1(或f1.fail()_) cerra：aaa.dat file not open!endl； exit(1)； for (int i=0；i=100；i+)_ f1_i ； f1. close()_； 五、1 编程求数列1，的所有大于等于0.000001的数据项之和并输出结果。1、#
