HW_2

Comments: So, for this program I never had too much trouble since,  we basically did the same coding process on homework 1.  This time, the questions just more specific on what the accuracy if the final  answer should be. I especially enjoyed the atomic weight code since. I'm not too sure why but I found it to be enjoyable. Asking for the user input and printing the results were pretty cool.

Comment: I had a lot of trouble understanding how to code works for the homework, I couldn't finish all of the modifications without getting an error. So I only finished the first three modifications, which took me a long time to develop. For this lab I initially had trouble getting the speaker to change the pitch according the the change in temperature. Turns out I had an extra if statement in my program and that resolved the problem. I spent about 4 hours debugging before I found the extra if statement. Also, I used a potomieter because the speaker would make the lcd screen go crazy since without the pot there was no resistance. /* This program determines the locations of peaks in an */ /* grid of elevation data. */ #include <stdio.h> #define N 25 #define FILENAME "grid1.txt" int main(void) { /* Declare variables. */ int nrows, ncols, i, j,count=0,count_2=0; double elevation[N][N]; double valleys[N][N]; FILE *grid; /* Read information from a data fi...

I couldn't figure out how to get the program to work initially, so I called Sam and he told me that he figured out to replace the underscore with a period for the f_fingertip. The program worked after and I took some time to figure out how to print the count and percentage of each category. Overall the modifications weren't too difficult once you figured out how to print the counts. /* Finger print program*/ /* It then references a function to compute the overall category.*/ #include <stdio.h> int k,l,j,i=0; double pow,pol,poa,arch_2,whorls_2,loop_2;//whorls_2 is equal to i becuase it must be double to calc percentage //pow is percentage of whorls /* Define a structure for the fingerprint information. */ /* The order for fingertips is right hand, thumb to pinky, */ /* and left hand, thumb to pinky.
