Hi
i am trying to call this search function in the main,
however i get an error for the following:Code:int search(int a[], int v, int l, int r) { int i; for (i = l; i <= r; i++) return i; return -1; }
if (v == a[i])
i am not sure why i get that error
thnx
Possibly because your counter should go fro 0 to < r. Arrays are indexed from 0.
Please post a code sample that acutally contains the line(s) with the problem...
Also, try and be more specific than "an error"
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Can you please make sure code is properly indented? It's easier for us to help you.

yes...
sorry i fogot to specify the error....
when i run it...theres a segmentation fault.
however, when i run it using gdb i get the following about that line
Program received signal SIGSEGV, Segmentation fault.
0x0804849b in search (a=0xbfcff524, v=2, l=-1076890280, r=134513913)
thanks
Did you do what nonoob suggested?
If you understand what you're doing, you're not learning anything.
I will take a wild stab in the dark and say that you have uninitialized values, because l is negative and hugely off-base while r is positive and hugely off-base.Originally Posted by papermate
ok...this is what i have done in the main
and it still doesnt work, also is my passing on correct
Code:int main( int argc, char *argv[]) { int a[]= {1,4,5,8,7}; int v=1; int l, r, i; printf("Enter an integer:\n"); scanf("\n%d", &v); search(a, v, l,r); if(a[i]== v) { printf("Found\n"); } else { printf("Not found\n"); }
The function search, needs to have it's code, *outside* of main(). The line that begins the function search, should be copied up above main() (not into main(), but above it), as a function prototype.
All your values for the parameter of search, need to have been assigned a value, before search is called in main().
You need to re-read your text, clearly. There's an awful lot of basic info that you have not yet learned, and you can't program anything like this, without that basic knowledge.
More study!

And where are l and r initialised (as per QuadraticFighter's previous comment)?
Simply declaring variables with the same name as the parameters in the function doesn't work.
