char title[20],;
char *p;
clrscr();
[Code] ......
Info:Program that stores information about reports .the above function searches the report according to its title. list is the name of the structure that stores the records.

I actually am wanting to practice on a 2 dimension char array. so, I am using the below program and getting the error - Lvalue Required For Function Main
#include <stdio.h>
#include <conio.h>
#include <string.h>
char varStringArray[1][5];
int main(void) {
clrscr();
varStringArray[0] = 'a';
printf("%c", varStringArray[0]);
return 0;

Im using the remquo function in the cmath library as follows:
int quotient;
double a = remquo (10.3, 4.5, "ient);
This gives the correct remainder (a = 1.3) and quotient (quotient = 2).
Infact about 50% of the answers are right when I play around, however, trying something like:
int quotient;
double a = remquo (2.25, 1.5, "ient);
yields an incorrect quotient of 2 and remainder of 0.
I do think this has something to do with float arithmetic. I recall tinkering with the float number 0.500 and that the CPU actually saves it as 0.50000000000000231. However if my suspicion of float arithmetic as the suspect is correct, I do not understand why a tenth decimal would make such a drastic difference as changing the quotient result.

I am getting this error when compiling my program with quincy:
Error: I value required as left operand of assignment
The program is meant to calculate how much parking costs based on the amount of hours in a park and what type of vehicle it is. the error is coming from my function definitions which i have just started to add in.
Code:
float calcCarCost (char vehicletype, int time, float car)
{
if ((time > MINTIME) && (time <= 3))
calcCarCost =( CAR * time );
}
The error is on line 72 which is:
calcCarCost =( Car * time);
I should probably point out CAR is already defined as a constant with a numerical value given and time is previously asked to be input in when the program runs.

Write a program in C that will allow a user to enter an amount of money, then display the least number of coins and the value of each coin required to make up that amount. The twist to this program is the introduction of a new coin - the jonnie (value = $1.26). Therefore, the coins available for your calculations are: Twonies, Loonies, Jonnies, Quarters, Dimes, Nickels and Pennies. You can assume the amount of money user enters will be less than $100.00.
User enters $4.53. Your output should be:
The least number of coins required to make up $4.53 is 4. The coins needed are:
1 Toonie $2.00
2 Jonnies $2.52
1 Penny $0.01
$4.53
I'm wondering if i'm close. I'm stuck on what to do for the output. This is what i have so far.
Code:
//Start
#include <stdio.h>
int main() {
//Get user input for amount of money
//Input
int i;
//Store input from user

When i try to compile this code it gives me a error during run-time saying "*program name* has stopped working"
Code:
#include <iostream>
#include <memory>
using std::cout;
using std::endl;
using std::unique_ptr;
[Code] .....
Why is this happening? Also why do you need the asterisk on smart pointers to assign them a value? Is it just because, or is there a reason.

You enter decimal number into the program and what base you want. The integer part of the decimal is being handled fine, but the decimal is not.
For example, I enter 15.6847 and base 10, which means I'm going from base 10 to base 10. It spits out 68469999999999 for the decimal part. (Do not worry about the first block of numbers. The second block seperated from the first by a space is where the decimal will appear in order.)
#include <iostream>
#include <string>
#include <math.h>
using namespace std;
int baseConverter(int, int, int *, int *);

You work for a painting company. Your job is to calculate the amount of paint needed for every contract assigned to the company. This time, you need to paint an outside wall. The dimensions of the wall are 5 X 7m. The window is a circle with the radius of 1m. Write a program that would calculate the following:
The amount of paint needed knowing that you need 1 gallon per 10 square meters. The amount of time to complete the job knowing that it takes 1 hour per 10 square meters to prepare the surface, 5 minute per square meter to pant it and 5 minute per square meter to clean up the area.

Goal: I want to use cygwin g++ to write DirectX applications.
I know that one of the mingw packages contain directx libraries.
Now that I have installed cygwin, can I use directx also?
BTW, does netbeans open a mingw project using cygwin tool chain?

I have written the following code to add data to text files which are required to store 3D scan data (I have to calculate the y-coordinate).

Code is shown below.

I'm trying to understand the pass by value-result. The code I have came up with so far only does by value and by reference, which I understand. The value-result is what has me stumped, and honestly I am unsure how to write the function for it. Here's my code so far...
#include <iostream>
using namespace std;
// Function prototypes.
void swapByValue(int, int, int);
void swapByRef(int&, int&, int&);

I keep getting an undesired value in this code. I've tried several methods, but none are giving me the correct answer. The out put is always zero, when in this case it should be 10!!
Here's the object structure:
template<class T, class _b>
struct quantity {
private: T value;
public:
explicit quantity(T val): value(val) {};
T getValue() { return value; };
[Code] .....
Here's the operation:
int main() {
quantity<int, bool> m(20);
quantity<float, bool> m_f(10);
quantity<double, bool> m_d(NULL);
m_d = m_f;
[Code] .....
Why does it seem that the assignment operator is the harder operator to overload? Maybe it's just my luck, but I seem to always run into issues whenever I work with it. I hardly ever experience errors when overloading any of the other operators.

//*Delcare function prototype*
int ConvertToCentimeters (double, double );

how to use the result of an if statement in my program. I'm writing a program for a knockout tournament, so i want to extract the winner of each match to carry forward in the code for use in the next round. I've tried assigning another variable (#define r1w1) and saying that the variable = cName[0] or cName[1] in the if statements like this: (i did this because i thought i could then use r1w1 later in the code)
if(scorea1 > scoreb1) {
printf("
");
printf("WINNER OF ROUND 1 MATCH 1 IS %s
", cName[0]);
cName[0] = r1w1
