gets在子程序中怎么使用
#include "stdio.h "
#include <iostream>
using namespace std;
char rulestr[100][100];
int rule_no;

void add_rule()
{
cout < < "Please type in the rules:\n ";
gets (rulestr[rule_no]);
rule_no++;
cout < <rulestr[0];
}


void main()
{ cout < < "(1). Add a filter rule:\n ";
cout < < "(2). Remove a filter rule:\n ";
cout < < "(3). Display filter rules:\n ";
cout < < "(4). Analyze filter rules:\n ";
cout < < "(5). Exit.\n ";
int comm_no;
do {cin> > comm_no;
if(comm_no==1) add_rule();

} while (comm_no!=5);


}

为什么子程序调用gets不管用呢？

[解决办法]
#include "stdio.h "
#include <iostream>
using namespace std;
char rulestr[100][100];
int rule_no;

void add_rule()
{
cout < < "Please type in the rules:\n ";
//cout < <rule_no < <endl;;
cin> > (rulestr[rule_no]);
rule_no++;
cout < <rulestr[0] < <endl;;
}


int main()
{
int comm_no;
do {cout < < "(1). Add a filter rule:\n ";
cout < < "(2). Remove a filter rule:\n ";
cout < < "(3). Display filter rules:\n ";
cout < < "(4). Analyze filter rules:\n ";
cout < < "(5). Exit.\n ";
cin> > comm_no;
if(comm_no==1) add_rule();

} while (comm_no!=5);


system( "pause ");
return 0;
}
