template in c++

Oct 9th, 2009

hi

Write an overload function "searchArray" so that it takes an
array "ary" of int or char, and additional argument,
namely "valu" with type as same as the "ary". A call to this
function will return the index of "valu" within "ary" or -1
if it does not exist.

and this is what i could write for now ..

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
int searchArray ( int ary[ ],int a){
for ( int i=0;i<=ary.length;i++){
if (ary[i]== a)
return i;
else
return -1;
}
 
}
int searchArray ( int ary[ ],int a){
for ( int i=0;i<=ary.length;i++){
if (ary[i]== a)
return i;
else
return -1;
}

}

it's not complete ..
any one can help me and make it 100% work

thanks

for the general search function, take the else return -1 out of the for loop. That return statement should only execute if you complete the for loop and don't find the search value.

int ary[] does not have a length member. You will have to pass the array length as an additional parameter.

If you google C++ templates you'll find a wealth of information on how to use them - as well as, maybe, reading your textbook? Take a stab at it and show us your work then.
