This program is our teacher to the framework of data structure
After I had finished my function, there is always an error//error: expected '; ', ', 'or') 'before' & amp; 'token
I would like to ask about the reasons for this problem, thank you all for elder

CodePudding user response:

Estimation is c does not support a reference type (c + + support)
The Status InitList (SqList & amp; L)//into a pointer type, SqList * L

CodePudding user response:

Your compiler error too much Suggestions according to the error of the IDE line by line

CodePudding user response:

Error: expected '; ', ', 'or') 'before' & amp; 'token
This error is usually in a row you forgotten; Or when an error

CodePudding user response:

Run into a similar problem is done with
/*... every time." */comment out different parts to recompile again, until orientation to the location of the specific grammatical errors, "
The methods to solve of,

CodePudding user response:

Suggest the landlord to confirm their own compiler, it is C or C + +, parameter, & amp; Is a c + + syntax rules, can try should * instead of & amp;

See the building there were cout
Code is copied, there are a few problems need to change,

//typedef ElemType; 
Typedef int ElemType; 

//return OK 
return OK;

reference 1st floor qybao response:

estimation is c does not support a reference type (c + + support)
The Status InitList (SqList & amp; L)//into a pointer type, SqList * L

He this estimate is to want to write C + + code, with the C just cout
