The code below

 # include & lt; Iostream> 
#include  
using namespace std; 
Void main () 
{
Char * ID [6]={" 10 ", "11", "12", "13", 14 ", "15"}, 
* telephonenumber [6]={" 6311 ", "5232", "2968", "6688", "8919", "3828"}, 
* name [6]={" Ming "and" zi ", "sui", "bian", "da" and "DE"}; 
Int I, order; 
Char * id; 
cout<" Please enter the student id: "; 
Cin> Id; 
for(i=0; i<6; I++) 
If (STRCMP (id, id [I])==0) 
{order=I; 
break; 
} 
cout<" Name: "& lt; cout<" Phone number: "& lt; } 

Has just started to learn, this is a job, enter student id and then output the corresponding name and phone number, array pointer what are still a little not too clear, then you really will not change ah QAQ hope I can help it right

CodePudding user response:

Oh what name is different in the screenshot program has privacy...

CodePudding user response:

Char * id;
cout<" Please enter the student id: ";
Cin> Id;

Id wild pointer

Char id [128]={0};

CodePudding user response:

Thank you me have a try on the second floor ps. Last night may be silly to enter student id name, I always loses.

CodePudding user response:

Your logic also incomplete, if the input to, order no initialization, may also lead to cross-border melt

The order=I; 
break; 
} 
} 
If (the order & gt;=0) 
{
cout<" Name: "& lt; cout<" Phone number: "& lt; } 
The else 
{
Cout & lt; <"Didn't find" & lt; } 
}
