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
[Code] ....
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);
[Code] ......
As you can see, I am currently stuck on the determineGrade one
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 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

Write a program which is used to calculate the GPA based on the grades for different courses input by user. User should be able to use this to enter grades for as many courses as he wants unless he wants to quit. (you may consider using some loop). Once user has completed entering of data, the program should be able to provide a feedback to the user about the GPA. A is equal to 4, B is equal to 3, C is equal to 2, D is equal to 1, rest are 0. Use minimum 5 course to demonstrate working of your code.
Here is an example (User input is in italic and bold):
Would you like to enter grades: Y
Please enter the course name: COSC1301
Please enter your grade: A
Would you like to enter more grades: Y
Please enter the course name:ITSE1301
Please enter your grade: B
Would you like to enter more grades: Y
Please enter the course name:ITSE2409

So I have to write a program to calculate a grade letter into a number.
Letter grades are A, B, C, D, and F, possibly followed by + or –. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F–. A + increases the numeric value by 0.3, a – decreases it by 0.3. If the letter grade is illegal (such as "Z"), then your output should be "INVALID LETTER GRADE"; If the combination is illegal (such as "A+" or "F-") then your output should be "INVALID GRADE COMBINATION"
Also the code should look like this
Enter your letter grade: C+
Grade value is [2.3]
// Input
cout << "Enter your letter grade: ";
string s;
cin >> s;
[Code].....
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 <stdio.h>
#include <stdlib.h>
main(){
int eg, g1, g2, g3, g4, fg, s1, s2, sg;

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>

#include <stdio.h>

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.

when I was looking for a way how to convert char into numeric value for std::cout I found some old discussion with this statement: Operations on unsigned int are typically faster than on unsigned char, because your processor cannot fetch single bytes but has to get at least a multiple of 4 and mask out the other 3 bytes. Is this true? By using smaller (in bytes) variable I actually slow down my program? I always thought that it is a good practice if I use the smallest variable which will do the work. Is it also dependent on a compiler and OS?
View 2 Replies View RelatedI want to avoid converting the char[] into a string as an intermediate step, since I'm trying to write some "string" parser helpers which don't allocate a bunch of different strings onto the heap. (whole point of this little project is to reduce GC pressure in applications that do alot of string parsing).
basically if I have a char[] that contains {'1','2','3'}, I'd want to to be converted into 123.
I tried messing around with the stackalloc operator in C#, but its illegal to stackalloc a string unfortunately. I also googled around for converting a char[] into a numeric value, but all the solutions convert each individual char into their ASCII code, or convert the char[] into a string as an intermediate step.
I want to create an object that uses visual C#'s Numeric Up/Down and a Track bar.
The reason is that I have a GUI that uses lots of these linked together with events and I want a common event handler for all of them.
Maybe just adding a property that is a Numeric Up/Down in the Track bar and vice-versa will allow me to create a common event for all of these pairs.

I have a button which selects a particular tab and tab page on a form. This tab page has an embedded tab control with several more pages.
When I click on this button, the desired tab page is selected, but the NumericUpDown value (which is on the tab page) is not visible. The value is the current year.
Could it be that somehow, the click event for the button is hiding the value?

I need to check my understanding from some questions about strings. How can numeric values stored as Strings be converted to numbers?
a)vector of required numeric data type
b)atoi function in cstdlib library
c)cout statement with required numeric data type
I picked b), I am aware of atoi, atol, and atof as methods to convert, but are there other methods?
What is the purpose of strncat function?
Combines n characters from source string into target string
C++ string provides:
a)convenient way to declare and manage character arrays
b)functions to manipulate strings
c)all of the above
d)none of the above
I picked c)
Write a program that reads in the numeric representation of a date and prints it out in a formatted manner as the box below.
1. If the user entered an invalid number for the month it should display "Invalid Month"
2. If the user entered an invalid number for the date it should display "Invalid Date"
3. Check to see if the day is outside the range for that particular month
An example of the input and the output:
Enter the date: 1 24 2013
The date you entered is: 1242013
Im not sure on how to go about this problem, but this is what I have.
#include <stdio.h>
int main(void) {
int a, b, c;
int status;
printf("Enter the Date");
status = scanf("%d,%d,%d",&a, &b, &c);
printf(" The Date is : %d",status);
return 0;
}
Am I going about this right? Is there an easier or better way to go about it? All that happens is that the program reads the first number and spits that back out.

Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be nearly the same as the data in the input file except that you will print the names as last_name, first_name and there will be one additional number at the end of each line: the average of the student's ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide where the last name comes first, then a comma and a space and then the first name. Use your read string function to read each name separately and then put them together into a larger correctly formatted string before trying to output them. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings.
This is how much I have so far:
