I need to get Students to input there Name And Score > and for me to output the grade. This works but I want to tidy this up so I can see all the names and grades when the program finishes.
#include "stdafx.h"

I am trying to correlate the student's highest score with that student's ID. The old code is in blue and the new code is in green which includes a sort. The particular information in question is in red.

Code:
#include <stdio.h>
int main(void) {
/*Set up two arrays to include up to 50 elements each.*/
int st_numval_id[50] = {0}, st_val_tstscr[50]= {0}, i = 0, j = 0, temp;
[Code] .....
Enter the student's id and test score:
/*After the following input, then enter 0 to end the input*/
Student ID Test Score Letter Grade
------------ ----------- --------------
1653 77 C
1945 72 C
1020 50 F
1955 92 A
1900 81 B
ABOVE AVERAGE STUDENTS
Ave Test Score Students Above Ave Number of: A's B's C's D's F's
----------- ---------- --------- --- --- --- --- ---
62.00 4 1 1 2 0 1
THE STUDENT WITH THE HIGHEST TEST SCORE
Student ID Test Score Letter Grade
--------- ---------- ------------
1900 0 F

I get so close, and then it seems my brain shuts down ... I need to write a program that outputs a histogram of student grades for an assignment. The program should input each student's grade as an integer and store the grade in a vector. Grades should be entered until the user enters -1 for a grade. The program should then scan through the vector and compute the histogram. In computing the histogram, the minimum value for a grade is 0, but your program should determine the maximum value entered by the user. Use a dynamic array to store the histogram. Output the histogram to the console. For example, if the input is:
20
30
4
20
30
30
-1
Then the output should be:
Number of 4’s: 1
Number of 20’s: 2
Number of 30’s: 3
I can't quite get my output to look like that:
/* This program will display the histogram of student grades for an assignment */
#include <iostream>
#include <vector>
#include <stdlib.h>
#include <conio.h>

How to traverse through this array and output each student and score that falls below the average. I think I may have the method down for traversing through the list to find the "total score" however, before proceeding under a possible wrong presumption, I would like confirmation as to whether or not I'm understanding this or botching this concept.
void dispLowScore(struct payload *arrayStart , //first element of array
struct payload *arrayEnd ) //last element of array {
int studentCount; //total number of students in list/array
int totalScore ; //accumulated value of all scores added together
float averageScore; //totalScore / studentCount
[Code] ...
The code runs but asks me for my score twice then just comes to an abrupt end with out giving me a letter grade.
#include <stdio.h>
int getScore(void);
char convertGrade(int numscore, char letterGrade);
void showGrade(int numscore, char letterGrade);
// Function to prompt for and read a numeric score
// Returns an integer score as read in using scanf

I have to get the average score for each student. And modify my avgmarks function and write the marks to a output txt file.

void filewrite();
void avgmarks();
void fileprint();
void filesort();

I am a math teacher who is taking a programming class. My district wants to incorporate some programming tasks into the high school math curricula. I am working on a project to calculate a final grade and output this along with a comment to a text file. The following data is the input that I created:
3 300 100 100 100 .15
4 400 100 98 94 92 .45
3 300 98 100 92 .40
The final grade output results in gibberish.

I'm writing a program to calculate a final grade by adding 4 numbers minus the lowest grade and dividing by 3. My knowledge in c is not extensive I thought that a simple assigment operator would do the job but I'm getting a strange large numbers in the execution.

#include <stdlib.h>
main(){
int eg, g1, g2, g3, g4, fg, s1, s2, sg;

I have to accept the numerical grade and determine the letter grade that the user will receive. I have to use a grading table to determine the letter grade based on the numerical grade. The Letter Grade table is
A 90-100
B 80-89
C 70-79
D 60-69
F 59 and below
Here is the code
//preprocessor directives
#include <iostream>
#include <string>
//namespace statement
using namespace std;
//function prototypes
void getData (string& course, string& first, string& last, int& grade);

I was tasked with creating a program that asks for the scores of three gamers then takes these scores and outputs the highest. I THINK I have the other parts down but I don't know how to get the program to compare the scores and output the highest without having to write a long list of commands comparing playerone to playertwo, then player one to playerthree, then player two to playerone, etc.

i'm having trouble with my c programming assignment. i'm trying to convert a number grade to a letter grade. I'm trying to Write a function (called: numToLetter) that takes as input a number from 0 to 100 and returns a character ( a single character ), based on the following: if the number is between 60 and 70 return Dif the number is greater than 90 return Aif the number is between 70 and 80 return Cif the number is between 0 and 60 return Fif the number is between 80 and 90, return B and i need to use the return statements to call the function like for example:
if (a > 90) return ('A');
elseif (a > 80)
return ('B');
elseif (a > 70)
return ('C'); else
return ('F');
how do if write my code with this function?
I am trying to code a program that takes in user inputted data about percentages and using it to later on calculate a final grade. 4 percents are inputted, for Assignments, Midterm1, Midterm2, and Finals. If the percents dont add up to 1 (i tell the user to enter the decimal value) I set up and if statement to catch it and end the program. Except that if i type in
Assignments = .3
Midterm1 = .3
Midterm2 = .3
Finals = .1
the program doesn't recognize that they add up to 1. Heres the relevant portion of my code [URL] ....
Here's some examples of how it works [URL] ....
And heres what i dont understand [URL] ....
Why is it saying .3 + .3 + .3 + .1 != 1 when .1 + .3 + .3 + .3 == 1?
I need starting a do-while loop in my program that runs up to 10 time that asks the user to enter up to 10 scores, which include the slope and rating for the course, and calculates the handicap for each score. Here's what I have so far:

#include <iostream>
#include <string>
using namespace std;
int main(){
int score, slope;
double rating, handicap;

#include <stdio.h>
float total, avg, max, min;
float judge[4];
int index;
int array[4];
int main() {
total = 0.0;
max = array[0];
min = array[0];
[Code] ....
I dont understand how to make the array when it prints out only print out the final average and the final maximum score with the final minimum score but what its doing at the moment is just giving an average for each individual score taken...
Minimum and maximum scores are displaying 0.0
And it displays these things 4 times in a row i just want it to be displayed once.
I have this code:
Code:
#include <stdio.h> //printf
#include <stdlib.h> //exit
#include <unistd.h> //fork
#include <sys/types.h> //pid_t
#include <sys/wait.h> //waitpid

I would like to, when running cat, send in some data like "testing" to its stdin, and then catch the output of stdout, and put it into a character array variable.Currently the parent stalls till the child is done.I imagine the parent has to some how detect that the child executed 'cat', and then send in input to stdin?Then somehow detect that 'cat' is done executing, and read the output from stdout? I have looked around and found "dup2", but I don't understand how to send in and get data to the child from the parent, especially since the "file descriptors" is not pointing to any files in the first place..
So I have a project in which I am processing audio signals in real-time. I want to create a class to do this using the ASIO driver. I don't want to use a cross platform library nor do I want to use windows API as it is very slow.

How to structure the input of one .dat file and outputting into another one. I have to loop through a file structured "doe, john, 1500", check for errors and then increase the mp by 50. You also have to do this through using a person class too. I think I need to use a while loop to go to eof and use getline to input correctly, but im not sure how to structure it.

for our school project, we have to make a program which involves three students and the prices each of them paid for the meals. The program has to calculate how much each of the students has to pay/receive to/from the others. Most of it, we got from our teacher. The error we are getting is that we have to 'take care of the input/output order'. So if you type in the names/numbers of the students in a different way, so for example if you type first number 1, then 0, then 2 and 0 and 1 have to pay money to number 2, number 0 has to be in front of 1. Our output is that number 1 is in front of number 0.

I'm learning C++. Is there some way to make program function on input from a port like usb port and can I send bits through the port? For example A usb cable connected to a circuit. I press a button and an AND gate on the circuit gets activated by a bit from the usb port and a fan in the room turns on.
