I am working on a program that is supposed to do I/O file streaming. I dont know if I can properly explain how its supposed to work but I have found the error on my code, I just dont know WHY the error is happening? If you look in the while loop, count changes values like it should, but MOVE and TIP doesnt. Count starts at value 2. So move is 108. Then count becomes 4, but move stays at 108?
Move wont change its value? It stays 108, causing this infinite while loop. Where is the error in my code to cause move to not change values like count does?
I seem to be struggling with I/O File streaming :(
I already made a nested for loop into a while loop (below this) and now I'm trying to make the outer for loop into a do while loop, but it's not working.
#include <iostream> using namespace std; int main () { int len; int j; int i;
[Code]....
And I can't make this code do the same thing. It stops after one loop, instead of continuing to the end. Why won't the loops continue?
#include <iostream> using namespace std; int main(){ int len; cout << "Enter a number: ";
I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code: #include<iostream> #include<algorithm> #include<vector> using namespace std; void change(double cents, int a[]); int main() { double Dollars; double cents;
We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.
I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.

how to use a keyboard. I have the program running now in Dev-C++, but the standard display letters on the monitor are small and sort of boring.Within a C program, is there a way to change the font to something stylish? Enlarge the letters? Change the color from letter to letter?
In the old days, there was graphics.h, but that isn't included now, and I would prefer to use some modern extension. I'd like to write it on Win7, then move it to Linux on Raspberry Pi. It would be nice to avoid a full-scale graphics system like OpenGL.
I have a .txt file which contains a large amount of ones and zeros (tile map for a game) and basically I just want to know how to change say just the 12th value in the file from a 1 to 0 .....
How to change directory in c++ ( windows ) I want to go to the folder "example2" and I delete some files and then return to the original folder c++ - windows
i have my basic C program here (i'm new to C language):
Code:
#include <stdio.h> int main() { int grade; int A=0; int B=0; int C=0; int D=0; int E=0;
[Code]....
As you can see, it's only for counting how many students got the grades from A to E, but the problem is that i need to change it from numbers into asterisk
for example: 4 students got the grade A, and 3 students got the grade B
I have installed VS 2010 and VS 2012. VS 2012 uses SqlServer CE 3.5 and VS 2012 uses SqlServer CE 4.0.The problem is that when a project uses a 3.5 file it tries to open it with 4.0 even if the app.config says to use the 3.5 provider. The version of the assembly is pulled right out of the GAC. I uninstalled 4.0 and the reference auto updated its version to 3.5.1. However after installing 4.0 again it changes to 4.0. The error I am getting is that 4.0 cannot open a 3.5 file....they changed the file format from 3.5 to 4.0 and they are not compatible.
On one of my assignments I have to find the optimal change. For example, if I were to have 70 cents and had only quarters, dimes and pennies, the best way to receive change using less coins all together would be 2 quarters and 2 dimes (4 coins all together should be displayed).
All in all, I understand my assignment, however there is something I don't know how to do (or can't recall how to) and that is finding the the highest number in an array to use in a function and be able to compare it.
#include<iostream> using namespace std; //function in which amount = money, changeArray is the array where money is stored, //and numCoins the amount of coin types there are available in the array
int optimalChange(int amount, int * changeArray, int numCoins) {
[Code] .....
What I'm stuck with, is that I don't remember how to get the highest number from the array that way I can compare it with the total amount when I'm building my function. Also, the function has to call itself recursively.
im new to c++ ,so my question is how do i change a length of a text. for example hi my name is blah blah blah. nice to meet you. (n i want every lines to have 8 chars how do i do that)
I have a program with the following code, and I need to be able to either change the value of any or all of the strlen or to replace one or all with a temp array value. All values of the expression are arrays.
if (::strlen(tc_buf) + ::strlen(maxtime_buf) + ::strlen(" ") < sizeof(localBuf))
For particular assignment, I am asked to evaluate data from an inputfile, let it be named "infile.dat". Next, it is required to output to this same file, but with the name of this file altered to reflect the changes of data. For example, if I want to change the original file name to "changed_infile.dat.altered" by adding the "changed_" prefix and ".altered" suffix, how could this be done?
From my understanding, there are no functions in <fstream> that could change the file name. However, there is a rename function in <stdio>, but it's not exactly what I am looking for because I want to append a prefix and suffix to this existing inputfile name. Although I could apply a brute force method by simply doing rename("infile.dat", "changed_infile.dat.altered"), I want to have my program to work with various input files of different names.
I am building a tamagotchi like application/game. As for the leveling up and changing of character I am using a char value so that the icon can change as the character progresses.
Due to the fact that the value for level is changing I need it to also change for what is being used for the case statements
I know I cant use variables in case statements because I have tried every way I can think of.
The code is
switch(Area[y][x]) { case '*': Area[y][x] = Level; break; case 1: { CODE } }
Where I have the case 1 I need it to change as level increases (as level is starting at 1)
