I am writing a code for a college project but i kept getting this error within it so i tried to resolve it in a separate program but i still can not resolve it. This is the error appearing... 1.cpp(38) : error C2448: 'validate' : function-style initializer appears to be a function definition could you please help. #include<stdio.h> #include<process.h> void getinforamtion(void); int i; bool bok; bool validate; int date; void getinforamtion(void) { do{ printf("\nEnter a number"); scanf_s("%d",&date); printf("%d",date); if(validate == false) { bok = false; } else if(validate == true) { bok = true; } }while (bok == false); } bool validate(bok = false) { if(i == 2) { return true; } else { return false; } } void main (void) { getinforamtion(); } Thanks alot

You are getting the error because you have already declared 'validate' as a simple variable: bool validate; but then you try to define it as a function: bool validate(bok = false) First, the signature is incorrect, it should be bool validate(bool bok = false) Secondly, you can't have the same identifier be both a variable and a function in the same scope. Most probably what you wanted to do was declare it as a function instead of a variable, in which case either define it before the point of first use, or have a forward declaration: bool validate(bool bok = false); Here are some further general comments on your code: #include<process.h> You don't appear to be using this header in the rest of your code. scanf_s("%d",&date); This is a Microsoft-specific extension. You shouldn't use it if you need to write Standard C or C++ code. if(validate == false) Experienced programmers don't write it like that, they write if (!validate) . if(validate == false) { bok = false; } else if(validate == true) { bok = true; } That is the same as bok = validate; Why say it in 10 lines when you can say it in one? Having said all that, I think what you meant was to call validate(), not validate. if(i == 2) { return true; } else { return false; } Just say it in one line: return (i == 2); Much clearer, isn't it? void main (void) That's not standard C or C++, in both languages main returns int, not void. Also, there's no need to put void in the argument list, just use ().
