 | [quote=WaltP;337125]For example, have you guys upgraded to Vista? XP is so old... :twisted:[/quote] Sorry couldn't resist this... Is Vista free ? I guess no. Good compilers are not hard to get by, so the only reason for not upgrading would be laziness or some genuine project constraint.... |

| | Arun, you need to properly format your code. Something like this: [code=c] void read_data() { int i,j,any; char yesno; char fname[15]; FILE *fp; clrscr(); gotoxy(10,10); printf("Data available in disk file Y/N "); scanf("%c", &yesno); if(toupper(yesno)=='Y') { clrscr(); gotoxy(10,10); printf("File name to read data "); scanf("%s",fname); fp=fopen(fname,"r"); clrscr(); fscanf(fp,"%d",&any); for(i=1;i<=n;i++) for(j=1;j=n;j++) … |
 | You forgot to close a double quote and main doesn't return void (atleast not in C/C++). Other than that the code really is good to go... ;) I think this should be better moved to the Geek' Lounge. |
| | You have just gone out to show one of the horrors of using the GOTO statement in C/C++... :D |
| | Don't forget to consider the following situations: • The blank lines may be composed of only spaces. You might need to write a trim function which first trims the lines read and then processes them. • The first line can be a non blank requiring you to initialize the flag … |

| | Possible in WinAPI if you know how to display images and make applications which are windowless(only an image in the center of the screen).

 | Simply said, in pass by value, a copy of the value of the variable is paseed to the function while the original variable remains unchanged. [code=c] void doubleValue (int i) { i = i * 2; printf ("\ni inside function is %d", i); } int main (void) { int i … |

| | [inlinecode]getchar[/inlinecode] and [inlinecode]getche[/inlinecode] functions just read a character, they serve no purpose in detecting when a key was pressed. You need to look into the [inlinecode]kbhit[/inlinecode] function which detects keypresses and then read the character using [inlinecode]getchar[/inlinecode].

| | [inlinecode]#define PI = 3.14159265[/inlinecode] This statement is wrong. Preprocessor statements are not written this way. The correct way would be: [inlinecode]#define PI 3.142[/inlinecode] or better yet [inlinecode]const double PI = 3.142[/inlinecode] |

| | Re: Error in output Some points: 1. Use code tags to post your indented code so that it is more readable. 2.
