hi guys i really need help on this programming, my program is not compliling and i need help. i also need to i dont understand what my program is doing in the loop.
Code:#include<math.h> #include<stdio.h> #include<conio.h> main() { float x,y; int i,j,k[5]; char letter, course[] = "numerical methods"; printf("%c %s\n", course[6], course); printf("%c %s\n", course[6], &course[]); for(i=0; i<5; i++) {k[i]=3+i}; j =*(k+2); printf("%d %d\n", k[2],j); getch(); }

It is not possible for a program to both "not compile" and "give output". Choose whichever one is true. If it does not compile, read the error messages, which will tell you exactly why it doesn't compile.
i got it form a tutorial book
Then you should fix the errors introduced when you typo'ed the program from the book (unless the point of the exercise was for you to find the errors in the first place). And the compile messages tell you why it doesn't compile.
And how hard is "k[i]=3+i" to understand? (Apart from that being one of your syntax errors, of course. But the intent of the line is obvious.)
Here is why it doesn't compile -
Empty subscript is invalid, you can simply do course, or &course[0]printf("%c %s\n", course[6], &course[]);
Semicolon comes before the curly brace.for(i=0; i<5; i++) {k[i]=3+i};
How are you getting output if your program didn't compile ?i dont understand why my the output is 3, 12
EDIT : ah, I see. Well step through it and see why you would get that output.
Spidey out!
my program still doesnt compile
Just reading about how to fix things won't help: you will have to actually make the appropriate changes in your program.Originally Posted by joker_tony

i try
i've been using C for less than 3 days, i see 4 errors. this code really doesn't need much to get it working.
what does the book say you are supposed to be getting for an output?

would you give me a favorutie and tell me what is wrong with it please
If you tell me what the output is supposed to be, ill point you in the general direction, as the rest of the replies have, but i'm not going to post a full program. Ill need the output to be sure I've done it right myself before i can offer accurate help.
output is
c numerical method
6 ,6

ok, what i want you to do is erase it and re-type the program from the book, and double check yourself, then if it wont compile, repost it. i wanna be sure i have the right program to start with
The code you posted has three output lines, and here you only have two lines of output. Another mistyping, I guess? And if you had typed the second part correctly then I would expect 5 and 5 instead.
