Type Mismatch In Redeclaration Of 'clrscr()'
like you, helping each other. Join them; it only takes a minute: Sign up Function declaration in C up vote 1 down vote favorite 1 I am learing C and would like to know is it possible type mismatch error in c++ to replace function call with function declaration ..like in below programme main() { void show(); getch(); } void show() { clrscr(); printf("Tendulkar is best batsman ever"); } here in main am declaraing show function and not calling it anywhere but still printf("Tendulkar is best batsman ever"); is getting executed.why is it so?? And one more thing guys when i run below programme on turbo c++ is giving me error but on gcc its work fine type mismatch in redeclaration of main() main() { show(); } void show() { printf("Tendulkar is best batsman ever"); } expected Answer: Compier error: Type mismatch in redeclaration of show. Explanation: When the compiler sees the function show it doesn't know anything about it. So the default return type (ie, int) is assumed. But when compiler sees the actual definition of show mismatch occurs since it is declared as void. Hence the error. c share|improve this question edited Mar 3 '11 at 8:07 asked Mar 3 '11 at 7:41 Amit Singh Tomar 2,4241263127 1 It doesn't get executed by my compiler (gcc 4.5.2, with #include added and the non-portable getch and clrscr removed).... What compiler are you using? –Tony D Mar 3 '11 at 7:52 1 @AMIT: well, it's good that nothing gets executed when it's outside main: I recommend just putting your declaration there then. There's no deep mystery to this - it doesn't work inside main because your compiler's old and broken - just accept that and get on with your work. You can then add an actual call to show() (without void in front) in main if you want to it to be called from there. –Tony D Mar 3 '11 at 8:01 1 I don't understand. You just updated your question and posted your own answer? So what is the q

Use [code][/code] tags when posting code. 2. main returns int, not void 3. Stop using conio.h. It is an obsolete DOS header file. Unless you're still using TurboC (another don't), you should be using things appropriate to this millennium. 4. Prototype the function above main(). In fact, anywhere before the first use. Like so Code: void display ( char *string ); int main() { char string[] ="hello string"; display(string); return 0; } void display(char *string) { printf("%s",string); } Comments on this post Technovicez agrees If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut

No doubt both have been mentioned before, obviously with no impression on you. 0 TkTkorrovi 69 9 Years Ago Look, the c compilers are made to be fast, there are compilers which use only one pass type mismatch in for finding all the symbols. Now you call your "square" function before you define or declare your function, so the compiler knows nothing about your function when it processes your function call. So you either have to define your function before, or provide a prototype. The latter is especially useful, because you later may want to make your function available to other modules, by include file. As this is so necessary, to declare what functions you would like to make available to the rest of the program, and what not, this is because any more complicated search for function names is not necessary in c. Because it is a good habbit to write function prototypes, and makes the code much clearer. And, don't make Salem angry with void main, there is a purpose for main to be int, and this has something to do with the rest of your system. When some "simpler" languages maybe are not made to work together with other programs, then c has been used all the time to write all the components of the system, and there, the program is not a stand-alone unit, but has to work together with other programs. The program would not always run separately, but can be used in a shell script as a part of some more complicated processing, or executed from inside of some other program. 0 letmec 9 Year
