I made a simple program to compute the lengths of a triangles sides, but when I enter 30 for angle and 10 for hypotenuse I get the opposite side is -9.880316 and the adjacent is 1.542514.
#include <stdio.h>
#include <math.h>
main() {
float angle;
float hypotenuse;
float adjacent;
float opposite;

C programming: I want to creat a program that asks the user to input the integer lengths of three sides of a triangle, and if so whether the triangle is a right-angled, acute or obtuse one. i am having some doubts about the if, else if statements. I never seem to know how and in what order to use them.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(int argc, char *argv[]){
int SideA;
int SideB;
int SideC;
}

Write a program to print a histogram of the lengths of words in its input. It is easy to draw the histogram with the bars horizontal; a vertical orientation is more challenging.

I'm trying to do this exercise from K&R on my own (with my own code), but I'm receiving a signal (Illegal instruction (Core dumped)) when the input is too large.
#include <stdio.h>
#define MAXWORDLENGTH 10
int main(void) {
int c; /* Character read */
long length[MAXWORDLENGTH + 1];
int reading_word = 0;
int word_size = 0;

Where the problem might be occurring. I tried debugging with GDB but found no useful information.
Program received signal SIGILL, Illegal instruction.

I am trying to code and compile a program that requests a uses to first inpu the number of sides they wish for a dice to have and secondly input the number of dice throws they would like to calculate the value for. The program will print an error message and default the number of sides the dice has to 5 if the number entered is below 4. Finally it will print out a percentage figure for each value that results from all the the dice rolls.
I have attached my header, driver and class files below along with accompanying error messages below them
// file name Exercise.cpp
#include <iostream>
#include "Die.h"
using namespace std;
int main() // the main program begins here

This code is not computing the averages.. I am trying to add up all the values in the array and divide them by the number of addresses in the array
Here is the snippet of what I have do far :
//Run through all possible train combinations

n_cars++;
num_trains=(.25*max_track)/tl;
num_people=n_cars*num_trains*4;

I originally had the user input three different lengths and then used this to determine whether or not it was a right triangle.
if(c==sqrt(a*a+b*b)||a==sqrt(b*b+c*c)||b=sqrt(a*a+b*b))
Now it has to be modified in order to accept the input 2,2 4,4 and 6,8(only an example) and be able to find out if it is a right triangle. I was told that arrays were not necessarily the only way to go about it.
I have an assignment that I have to make a 3x3 magic square that sums up to 15 on all sides. I can't use arrays, just Loops and If and Else statements.
My first attempt was like this
//Program for printing magic square that sums up to 15.
#include <iostream>
using namespace std;
int main() {
int a, b, c, d, e, f, g, h, i;
int r1, r2, r3;
int c1, c2, c3;
[Code] .....
I can't think of a way to loop that when it prints out, it will have a sum of 15 on all sides and/or print one of the 8 solution for a 3x3 magic square.
I'm making a program that prints a triangle of @ signs given rows (but not columns).

It seems that it's just missing a space (and therefore a setw and setfill), but I found 2 problems:
1. The space needs to not apply to the first line.
2. I can't get it to make a space before each row without making a space between each column.
My current code is:
#include <iostream>
#include <iomanip>
using namespace std;
int main ( ) {
int rows;

I have tried putting in << setws and << setfills of various values but it seems to always apply to between each column as well as at the start of each row- what do I do?
I have a program that prints out pascal's triangle. One problem: it isn't a triangle. The output doesn't work. This is what it should print:
Code: How many rows: 4

1 3 3 1
1 4 6 4 1 and this is what it does print: Code: Enter a number of rows: 4

How to do the function part here is the question. "Write a program that calculates the hypotenuse of a right triangle. the program should ask the users to enter the length of the two legs of the right triangle and the program should call a function hypotenuse() that will calculate and display the length of of the hypotenuse. NOTE: The program should include a prototype for the function hypotenuse()" i have this so far

How to do that. It's rare that I post without figuring anything out, but I'm just simply not sure. I have a program that prints a triangle in a similar direction, so maybe if I could get some hints as to what to do with that (HINTS, not direct source code) .

How to get void Triangle::setBottomLeftX(const double x) to work.
Implement the get and set member functions for the class Triangle. Use the appropriate class attributes of the class Triangle.
a. The location of the bottom left vertex is stored in the member attribute blPoint.
b. The top left vertex can be computed from blPoint and the height.
c. The bottom right vertex can be computed from blPoint and the length.

I'm trying to write a little C++ wrapper around the PolarSLL SHA-512 / 384 implementation, the source code of which you can view here: [URL] .....
The problem I'm having is that the length of the digest is not always 64 bytes (for sha512) or 49 bytes (for sha384) as it's supposed to be, it often is, but not always.
I have pretty much used the code as it is on PolarSSL's website, except for wrapping it in an "impl" namespace. I also ran the self_tests, which all passed.
Here's the code I'm using to wrap the PolarSSL implementation:
namespace {
void sha4(const std::string& input, const sha_t& type, std::string& result) {
bool is_384 = (type == sha_t::SHA_384);
const unsigned char* in = reinterpret_cast<const unsigned char*>(input.c_str());
[Code] ....
When I do a strchr() for '' on the original (non-hex) values, the pointer position returned is the same as the checksums length, so I'm wondering if perhaps the sha4 implementation would shift bits around and one of them happens to become a '', null terminating the hash early?
double compute_taxes(double gpay) {
double gross;
double td; // to hold the tax deduction
if (gross <= 1000)
td = gross * 0.5;
else if(gross < 1500)
td= gross * 0.6;
[Code] ....
Write the function double compute_npay(double gpay) that receives an employee's gross pay using the value parameter gpay, computes the net pay and returns it. the net pay is the gross pay - the tax deduction. To compute the net pay, it first calls compute_taxes() to compute the tax deduction.
What is wrong with this code cause im not getting the correct ratio of total people to cumulative length?

How to do recursive function for the following?
RecursiveComputeRouteDistance(p1index,p2index,locations,latitudes,longitudes): recursively computes the total distance between all waypoints (route) using computeDistance function to compute the distance between two adjacent points.

View 6 Replies View Related One of my class assignments is to create a program that receive a .txt file containing a students name and their grades as follows: John K. 99, 87, 57, 89, 90, 95 Amanda B. Jones 100, 88, 76, 99, 86, 92 etc.. The number of students is unknown until run time. You have to take those grades and average them weighing the first (4) at 10% a piece and the next (2) at 15% each and the final at 30%. Then return an output file with the students name and their letter grade A,B,C,D,F based on their computed score. In addition, on screen it needs to display the average scores for each Q1, Q2, etc. as well as the minimum and maximum for each test on the screen. I am having a hard time in assigning the scores to a variable so that they can then be computed as an average and then used to determine a letter grade. I have begun to write the code and am a bit stuck..here's what I have so far:
Code:

// Final Exam

The problem I'm having now is how to go about passing the grades to the function computeGrade and then compute the average and return that to the function.
