Help printing on screen

Expand Post »

Hi all
My friend sent me this C++ program that opens up notepad and starts typing, its a joke he made to scare his little brother, I tried to modify it to display more of the message "Im watching you" but when I do it wont compile and I dont understand the error message, Im a noob lol
Heres the code all I did was copy and paste the spooky message a few more times underneath the original spooky messages, so instead of displaying the message 4 times it displayed it 6 times

#include <windows.h>

using namespace std;
 
 
int main(int argc,char *argv[])
{
 
//hides your program from the desktop

ShowWindow(hwnd1,SW_HIDE);
 
//array for your messge
char text[75]= {'i','m',' ','w','a','t','c','h','i','n','g'

>it wont compile and I dont understand the error message
And we're supposed to divine what that error message is? Maybe you should post it.

Re: Help printing on screen

Sorry stupid me here they are 3 of them
In function 'int main(int,char**)':
too many initializers for 'char[75]'
[Build Error] [ghost4school.o] Error1

I thought the second message meant too many letters because I had only declared 75 but I counted the original number of letters and that went over 75 so I have no other ideas

Re: Help printing on screen

>too many initializers for 'char[75]'
By my count you have exactly 75, so either the code you posted isn't the same code you've compiled, or you're getting a strange error. In fact, it compiles okay for me. Try removing the array size and using sizeof text in the loop instead of 75. That should sidestep the problem.

Re: Help printing on screen

>what are you counting?
I'm counting the number of character literals. Alternatively, you can count the number of commas and add one. Anyway, you're making this harder on yourself because you could just do this:

C++ Syntax (Toggle Plain Text)
const char *text =
  "i'm watching you... "
  "i'm watching you... "
  "i'm watching you... "
  "i'm watching you...";
const char *text =
  "i'm watching you... "
  "i'm watching you... "
  "i'm watching you... "
  "i'm watching you...";

Then instead of counting the number of characters, just traverse until you find '\0'. Much easier.

Re: Help printing on screen

You neglected to make all of the changes I suggested. Change this:

C++ Syntax (Toggle Plain Text)
for(int i=0;i<75;i++){
for(int i=0;i<75;i++){

To this:

C++ Syntax (Toggle Plain Text)
for ( int i = 0; text[i] != '\0'; i++ ) {
for ( int i = 0; text[i] != '\0'; i++ ) {

It should only print four messages, because that's how many you've defined. In fact, that's precisely what it does for me. Did you post the actual code you're using?
