function problem

hagarr (11)
I'm doing a program that outputs average high/low temps and the highest/lowest temp.
They all work except for lowest temp which always comes out 0. I don't know what to do. Any help would be appreciated. The problem function is indexLowTemp.

Edit- I changed some things around

In the protoype of indexLowTemp, you declare the argument indexLowTemp[cols][cols] whereas you actual function is indexLowTemp[rows][cols].

Yeah, I caught that after I posted. It still didn't work though.

Did you just fix it or did I read it wrong?
hagarr (11)
Yeah, I edited my post.

anyone?

int lowestIndex = 0;

If all the temps are > 0, you won't ever modify it. Just set it to the be the first temperature in the row.
