EXERCISE 1 Suppose that nValues and dValues are functions of one argument (the termindex)that return the ni and di of the terms of the continued fraction. Define the function cont-frac such that evaluating cont-frac(k) computes the value of the k-term finite continued fraction. Check your procedures by approximating 1/φ using …

Hi! I have a hexadecimal word in the form of a string, and i need to convert it into binary. For eg : AA FF (there is a space in between the two parts). How do i convert this into binary ? Thanks in advance :)

If you carefully look at this example you will see with atoi when it runs into a string it gives the integer value of 0. So I was wondering how you tell the difference between the integer value of 0 and a string that got converted to 0. http://www.tutorialspoint.com/c_standard_library/c_function_atoi.htm

Is the ordering of checking if a number is between two values important? I figured this would be pretty simple to do but its not working. if(0 <= (int)strings[p][0] && (int)strings[p][0] <= 9) { printf ("NUM: %s\n",strings[p]);; } else { printf ("ID: %s\n",strings[p]); }

Write a function sin Left(a, b, k) that estimates the area under the sin function in the interval from a to b on the x-axis (where a≤b) by dividing the interval intoksub-intervals and adding up the areas of the rectangles in each sub-interval. The height of a rectangle in a …

I'm having trouble with the if statement. I have verified with print statements that (int)strings_line_tokens[l][m] == 0. I thought maybe my logic was backwards since I had two not statements with an or, so I changed it to an and. That didn't help either. if((int)strings_line_tokens[l][m] != 10 || (int)strings_line_tokens[l][m] != …

Hello, this is a very strange problem. I had first put this discussion in the Linux and Unix thread, since I believe it is actually a problem with how the data is entered via but the vi editor, but I closed those out and will put it in the C …

Hi, how to make counting numbers ? For example, I send command to HyperTerminal, then it will reply (print) counted values. Here the first example, send command: UI1-UI10 reply command: UI1-UI10_in_Hexadecimal:0x3FF The above example, Ui1 until Ui10, it count, one until ten. Then, the binary will have IIIIIIIIII (10bit), but …

I have seen both ways for reading file error messages. Is one better than the other? Is exit(0) better than return 1 or vice versa? FILE *fp; fp = fopen(argv[1], "r"); //Open file for read. if(!fp) { printf("Error opening file %s!",argv[1]); //Program prints error message and closes if file is …
