Quick Question about my code

 
0
 

ok so basically my code is complete but I keep getting an error on one of my brackets and it says I need to put a ' ; ' behind "int LinearSearchArray ( const int list[], int numEless, int value)" and when I do that it brings up more errors. Besides the bracket error my code is complete. The error is at the bottom of my code and I made a comment with a arrow pointing to the error. Thanks

1) USE CODE TAGS!
2) Format your code.
Almost all errors like this can be avoided by proper formatting.
3) Never tell us what the error says, post it verbatim (copy/paste)

int LinearSearchArray ( const int list[], int numEless, int value)

{ //<<--------this is where I get my error
int index=0;
int position= -1;
bool found = false;


while(index < numEless &&!found)
{
found = true;
position = index;
}

index ++
}
return position
}

There is no semicolon after last two lines
index++ and return position

Your "LinearSearchArray" function is defined within main() - it needs to be defined globally. Also, you have 5 brackets in this function, so you either have to add one more or remove one. Having an odd number of brackets is never a good thing!

Ooops - sorry, your function is not defined within main(). However, you do have 13 brackets in main(), so again, you need to add one more or remove one.
