I want the 'counter' loop to go through twice, each time reading in 15 characters from the standard input, then going through the evalutor
Code:
#include <stdio.h>
#include <ctype.h>
int main (void)
{
char inputtedhand[64];
int NumC=0, NumD=0, NumS=0, NumH=0;
}

So I have to write a step in my program that reads in up to 8 variables. Simple, but if the User submits an invalid value, I have to give an error message and ask him to re-enter the value until he enters a valid number. Here's my while loop that works perfectly:
Code:
while (true) {
printf("
Enter the mark given by Judge 1: ");
scanf("%f", &m1);
if ((m1 >= 0.0) && (m1 <= 10.0)) {
break;
}
[code]...
I'm not sure what to write in the else statement to make the programme understand that it has to repeat the exact same step but without adding 1 to index. Is this possible or do I have to suck it up and just use while loops instead? I'm very new to programming.
Design and implement the class myArray that solves the array index out of bound problem, and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements:
myArray<int> list(5); // Line 1
myArray<int> myList(2,13); //Line 2
myArray<int> yourList(-5,9); // Line 3
The statement in Line 1 declares list to be an array of 5 components, the component type is int, and the componentst are : list[0], list[1]…list[4]; the statement in Line 2 declares mylist to be an array of 11 components, the component type is int, and the components are: mylist[2],…mylist[12].
This is what I have so far:
#ifndef H_myArray
#define H_myArray
#include <iostream>
using namespace std;
template <class myArray>
class myArray
{
public:
private:
return 0;
};
#endif
I've been making a project that requires different files to have access to objects declared in other files such that circular dependencies are created. I've done some research and discovered that pointers and forward declarations should be able to fix this.
Example:
File 1 declares variable x, must edit x and y
File 2 must edit x and y, declares variable y
I know this isn't the best example, as you could probably declare x and y in the same file, but please suffice it to say that I'm unable to do that in my project.
Im writing program for a rail fence cipher that should run from the command prompt and take in two .txt files, one containing the key for how many rails there should be (between 1 and 25) and the other containing the message to be encrypted. Both of those txt files should be entered from the command prompt, taken in with the program's arguments, not asking the user for input I think I have the logistics of how to get the program to encrypt it worked out, but every time I try to run the program it keeps on crashing.
The program should run when I enter this:./railcipher samplekey.txt samplemessage.txt
I'm pretty sure my issue lies within my first few lines of code, with the main(), or with the FILE*, but I dont know what I would need to change it to for it to work properly.

#include <stdlib.h>

If I have an array and all I have is an upper limit on how big the array can get, and if the number of elements that get added can be considerably smaller than this limit, is it always the right choice to declare a pointer and just reallocate extra memory whenever the array grows? For instance, instead of declaring int a[max] I can declare a pointer int *a and than just realloc when I add elements.

We had to write a "selling program for computers, laptops and tablets", which I did but for the extra credit, we have to have those three points in the application and I have tried but how to do the "extra credit" part, which I really need.
1.) A loop to prompt the user if they would like to place another order
2.) At least one user-defined function
3.) An enumerated data type, array or struct (structure)
I did one of these three, it's a "DO WHILE" loop asking users if they want to make another order, it's right at the beginning of the code.
Code:
#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
using namespace std;
double desktop();//function prototype
double laptop();

int main() {

View 2 Replies View RelatedI have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?
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.

Loop is repeated an additional time as shown in the screenshot:
Given a for loop:
int i;
for(i = 0; i < 1000; i++)
;
How many nanoseconds, or microseconds or milliseconds does it take for each iteration? And why do some use it as a timer mechanism?
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;

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?

int len;

I need to convert the following while loop:
count = 1;
while (caloriesForItem != 0, count != numberOfItems )
{
cout<<"Enter the calories: ";
cin >> caloriesForItem;
totalCalories += caloriesForItem;
count++;
}
This is what I have come up with:
totalCalories += caloriesForItem;
for (count = 1; caloriesForItem != 0; count != numberOfItems)
{
cout<<"Enter the calories: ";
cin >> caloriesForItem;
count++;
cout << "Total calories eaten today = " << totalCalories << endl;
}
However the output is not the same?

I'm pretty new to C++ and I'm on Binary Trees in "Jumping into C++"! I've just created a DLL project on Code::Blocks, and I cannot get it to build and run: "You must select a host application to "run" a library..." is the message that I'm getting when I run the main code file. It's had no changes to it (except for a few extra, unnecessary line feeds), and it's the file which Code::Blocks generates on a DLL project.
View 13 Replies View Relatedwhats wrong with this code, I'm trying to parse a .js file and replace all the ";" with "; " i.e add a new line after each ";". So I load the file into a char[] buffer then assign a string to this contents of this buffer. Then loop char by char through using an iterator and check for a ";", if found use replace. So int i gets to about 85898 then crashes with unknown error, 'i' should reach about 175653. It does work up till it crashes. And, is this not a simpler way to load a file into a buffer, there is in C.

I have a function that needs to return a "uint8_t" value. However before doing the processing I need to perform a test on the argument to check if it's between expected boundaries. Although this function works it gives (a logical) warning that not always a value is returned although expected. What is the normal way for functions like these where I normally should return e.g. -1 in case the test doesn't succeed and otherwise the uint8_t (t) value?
Code:
uint8_t myFunc(int a) {
if (a >= 0 && a <= 100) {
// Perform actions
uint8_t = ...
return t;
}
}
