Basically, say i wanted to sum all the values enter for x. First, i ask the user how many x's there are, then create a "for" loop to ask for x1, x2, x3, .. xn. Then i want to know the cumulative total of x. How would i do this? This is the sample code i have made right now inside of my main function:
Code:
int N;
int I;
int X;
//This is where i ask for how many x's there are//
}

Write a program that computes a running sum of inputs from the user, terminating when the user gives an input value of 0
Using a while loop - no problem. Its only when I try to code it with a for loop that the program doesn't terminate with a 0 input. It terminates with a -1 input!!
while loop
#include <iostream>
using namespace std;
int main() {
float input=1;
float sum = 0;

I am trying to create a loop to call in the entries from the text file named Set. The entries of Set.txtare :
1 2 3
2 4 5
and so on .. (64 such combinations)[/CODE]
It basically means the first combination for testing is 1 2 3 and next has to be 2 4 5 and so i have 64 such entries defined in set
My test files are located in D://data// and are named tst_data1 to tst_data64.
I created a loop for test set but its incorrect
Code:
// loop for test samples
char basefilename[] = "D://data//";
char , testFilen[160], numiChar[10];
for (int i=1; i<=64; i++) {
strcpy(basefilenme, "D://data//");
strcat(testfilename, Set[]);
[Code] .....
How can i call the Set .txt and how to define it.
Write a program in C/C++ that counts and summing the elements (numbers) from the given interval in the array.
View 3 Replies View RelatedSo the question is to let the user put in two integers and put each integer in an array as separate numbers, and then sum these arrays together, so putting in the array is not so difficult, only problem i am having is first when the user have to input the first integer, he have to put space after each number, second then I am not sure how to sum them up, so if 45676 is first array and 56717 is second, we have to start summing them up from 6 and 7 (the last numbers). Here is what I did for now:
#include <iostream>
using namespace std;
int main () {
char Num1[5], Num2[5];
int i1; int i2;
cout << "input the first number" << endl;
for (i1=0; i1<5; i1++)
cin >> Num1[i1];

I'm creating a program that is combining functions to show a menu to a user then the user picks numbered items which results in the totalling of a bill for them.
Where I'm stuck is after they're entered their selections, how to take them and sum them up. I've been trying with a switch statement, but I'm not sure if this is the right method. Is it even possible to sum separate cases of a switch statement together? Below is the code I've gotten so far:
#include <iostream>
#include <iomanip>
using namespace std;
void showMenu ();
void showBill (double, double, float, double);
void changeDue (double, int);

I have to make a grid 40 X 40 with random numbers 0-9. I have already done this and it prints out great. My problem is I need to be able to choose a row number and output the sum of the number in that row. Here is what I have so far.

I am having a problem with my program to calculate the GPA of a student. The problem that I am having is that I am not able to get my Total Point Value to display the sum of the two arrays. The multiplication for the array is correct and will display correctly, but instead of putting the total into the accumulator it will display the totals in a column. I have tried moving the coding for the calculation out of the loop that converts the letter grade into a point value,and placing it in it's own loop, but I still get the same display output. Below is the code that I have so far. I still have a few elements to add to the code, but they will be easy once I get this display to work right.
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
// Global const
// prototype
int main () {
// Varialbes, Arrays

Write a program that reads characters from the keyboard using the getch() function. All lower case letters will be converted to upper case and printed out to the display using the putchar() function. All uppercase letters will be printed using putchar(). All individual digits will be accumulated and the sum will be printed at the end of the program using printf(). You will write a function to return the upper case of the letter and a second function which receives the current sum and the character digit.
The convert digit function will convert the character digit to a decimal value and accumulate the digit to the sum returning the new sum. Only the letters will be printed out nothing else. The program will continue until the return is received at which time the sum of the digits will be printed on the next line. What was entered: a9 wF23’;/4i What the line actually shows: aA9wWFiI The sum of the digits is: 18

When I compile I get this error:
Code:
simpleauth.c: In function ‘initialize_table’:
simpleauth.c:179:30: error: incompatible types when assigning to type ‘DBEntry’ from type ‘void *’
I am sure its a simple error but I cannot seem to figure out how to set all the entries in the database to NULL. My plan is this:
1. Set all entries to NULL.
2. Check if entry is empty, if empty insert into hash-location, if not increment until empty...
Part 2 seems easy to me, but I cannot set them to empty....
how to do this? ask the user to input entries of 10x10 array. sort each column into increasing order. print out the array with sorted columns?

I am learning how to do this before I can move on so it can read a text file of numbers.
Also I am having problems with ////delete [] a[];///// I took it out because it made my code compile and run but when I add it in, it gives me an error:

I know this expression is suppose to deallocate the array.
I have an issue with a database call. I've got a database call that counts the number of entries in the database:
private static Int32 dbCount() {
SqlCommand cmd = new SqlCommand("SELECT COUNT (*) FROM Employees", conn);
conn.Open();
Int32 count = (Int32)cmd.ExecuteScalar();
conn.Close();
return count;
}
Afterwards I'm using this as a check throughout my application:
if (dbCount > 0) {
// do something
}
When I execute this code I'm getting the following error: "Operator '>' cannot be applied to operands of type 'method group' and 'int'"
So I'm guessing it has something to do with the cast of the dbCount-object but I don't understand why as I already stated that the count-object to be an Int32.
