hi this is the code that i have but i seem to have 2 errors and i dont understand were they are so can some one please help me. thanks

this is the code
#include<iostream.h>
#include<conio.h>

struct faculty
{
char fact1;
char fact2;
char fact3;
};

struct dean
{
char dean1;
char dean2;
char dean3;
};

struct seniorlecture
{
char seniorlec1;
char seniorlec2;
char seniorlec3;
};

struct secretary
{
char sec1;
};

void main()
{

faculty uni;
dean uni2;
seniorlecture uni3;
secretary uni4;

uni.fact1='business';
uni.fact2='law';
uni.fact3='engineering';

uni2.dean1='john';
uni2.dean2='sara';
uni2.dean3='jane';

uni3.seniorlec1='sam';

struct faculty
{
char fact1;

char fact3;
};

faculty uni;
uni.fact1='business';
uni.fact2='law';
uni.fact3='engineering';

Hi There,
According to the declaration above you have a structure named faculty which has three members. Those members are of type character (i.e) it can hold only one character at a time. for (e.g) you can store uni.fact1='a';
So if you want to store a array of characters in fact1 you have to decalre fact1 as character array as
char fact1[50];
now
strcpy(uni.fact,"Business"); will work.
Try this. If you have any problem do let me know,
Thanks and Regards,
Aarthy.

could you show me what you mean as it is the first time i'm using c++ and i dont understand how i'm going to add the changes that you have told me to put in the program.
thanks

Here goes the program,

#include<iostream.h>
#include<conio.h>

struct faculty
{
char fact1[50];
char fact2[50];
char fact3[50];
};

struct dean
{
char dean1[50];
char dean2[50];
char dean3[50];
};

struct seniorlecture
{
char seniorlec1[50];
char seniorlec2[50];
char seniorlec3[50];
};

struct secretary
{
char sec1[50];
};

void main()
{

faculty uni;
dean uni2;
seniorlecture uni3;
secretary uni4;

strcpy(uni.fact1,"business");
strcpy(uni.fact2,"law");
strcpy(uni.fact3,"engineering");

strcpy(uni2.dean1,"john");
strcpy(uni2.dean2,"sara");
strcpy(uni2.dean3,"jane");

strcpy(uni3.seniorlec1,"sam");
strcpy(uni3.seniorlec2,"pat");
strcpy(uni3.seniorlec3,"'tom");

strcpy(uni4.sec1,"kate");

cout<< "Faculty is:"<<uni.fact1<<endl;
cout<< "Dean of department is:"<<uni2.dean1<<endl;
cout<< "Senior lecture of department is:"<<uni3.seniorlec1<<endl;
cout<< "Secretary of department is:"<<uni4.sec1<<endl;

cout<< "Faculty is:"<<uni.fact2<<endl;
cout<< "Dean of department is:"<<uni2.dean2<<endl;
cout<< "Senior lecture of department is:"<<uni3.seniorlec2<<endl;
cout<< "Secretary of department is:"<<uni4.sec1<<endl;

cout<< "Faculty is:"<<uni.fact3<<endl;
cout<< "Dean of department is:"<<uni2.dean3<<endl;
cout<< "Senior lecture of department is:"<<uni3.seniorlec3<<endl;
cout<< "Secretary of department is:"<<uni4.sec1<<endl;
}

getch();

So compile the above program and see the result. I have changed the declaration part. Basically in C and c++ you can't assign strings using equal to sign. You have to use strcpy function. Hope this helps you,
Aarthy.

i had done what you said and used your program i had more errors then before one of the errors was saying that i can not use the stycp so i took it out and have still 2 errors on both errors it says the following

error C2015: too many characters in constant

[ser]

can someone please help i can not solve this error

[Banfa]

I am betting where aarthy82 had

"business"

in their code you still have

'business'

as per your original code. "business" is a string constant and can contain any number of printable characters, where as '...' signifies a character constant and can only contain a single character, i.e. 'b' so 'business' has too many characters in it for a character constant.

[ser]

i understand whta you are saying but how can i put it in the code.????

[ser]

i have added some changes but i have know got more errors then before i need help asap as i have to hand this in tommorow. this is teh code that i have so far and i have been trying but i just dont get this c++
[code]
#include<iostream>
#include <string>

struct faculty
{
string fact1;
string fact2;
string fact3;
};

};

struct seniorlecture
{
string seniorlec1;
string seniorlec2;
string seniorlec3;
};

struct secretary
{

};

int main()
{

}

return0

ser-

From what I can see, there are only three minor syntax issues with your completed code.

1) the includes

You declare the two includes, and you don't specify a namespace. Merely put underneath those two

using namespace std;
 

2) brackets

Any loops you create should have matching { } brackets. Whenever I code, if I'm going to do a for loop, for instance, I start with for () { } just so I don't forget them. You have a closing bracket for your main() routine above the return 0.


3) statement closure

All complete statements (aside of loops), should have a ';' finishing them off. You left this off on the return 0

    return 0;
}
 

And your code should compile and print.

can someone help this code i just dont understand how i'm going to make the code work i have tried another way but i have some errors and i dont understand what i'm doing wrong.

getche();

[sicarie]

Ok, this is where "reading" comes in handy. I told you the three things that were wrong with your code, just go back and look at them. You didn't even fix the one where I told you what to put and where. I don't know what getche() is, but it should be return 0;

dont worry i had to think abit and i have sorted it out so thanks for your help i have now finished the program and it works. thanks again

and this is the error message that i have

[too many characters in constant]

i think the error is because u cannot have more than 2 chars in a char variable.

[gsi]

Hi,

i think the error is because u cannot have more than 2 chars in a char variable.

A variable of data type ' char ' can never hold more than one character, Internally the character itself is represented as an integer constant (Its corresponding Ascii code as an integer constant).

Thanks,
gsi.
