I have a simple input output problem using float point numbers and after the first input the program skips the other cin functions is there something that I did wrong? It compiles fine also.
Code:
#include <iostream>
#include <float.h>
using namespace std;
int main() {
int x;
int y;
int z;
[Code] .....
Here is my code:
int main (int argc, char* argv[]) {
int x = atoi (argv[1]);
int y = atoi (argv[2]);
int z = atoi (argv[3]);
if (strcmp(argv[4], "Simple") == 0){
[Code ....
I need to convert the output of simple interest to float which is $5184.90 instead of $5180. how to go about it?
I am learning c because I want to get back into programming microcontrollers, which I previously did in assembly. I wanted to make something fairly tight in terms of program memory and RAM to show me an output in binary form. When you are troubleshooting a file register or serial interface when you can see the actual bit values (on a small LCD for a micro-controller) and compare it to a datasheet.
Code:
#include <stdio.h>
#include <math.h>
int main() {
int i;
int decimaltoconvert;
int convertingarray[7];
int convertingarray2[7];
[Code] .....
Also, how might I go about putting that into a function that I could call?
I need to write a program that reads four float numbers from the input.txt file, then it prints out the greatest of the four numbers into the output.txt file. I did everything, but the numbers don't print out.

using namespace std;
int main() {
ifstream inFile;
ofstream outFile;
float number1, number2, number3, number4;

How to do the problem below using loop?
Input numbers until the user types a 0, then output the product of the non 0 numbers: e
E.g., if the user types 2 4 6 0, the program should output 48
how can I check if the number is float point number without converting the number to string and then find '.'?
For example, this number (5.0) should not be integer. I found the following way in Python but it didn't work in C++
abs(n - (int)n) < 0.000001
I have a program that runs fine but outputs garbage and skips processes when I input a decimal. It compiles fine and has no errors.
Code:
#include <iostream>
#include <float.h>
using namespace std;
int main() {
int x;
int y;
[Code] ....
I was going through the exercises in one C programming ebook.There is this question which asks me to print a float variable in fixed decimal notation, field size of 6, right-justified, no digits after decimal point.I got printf("%6f", x );
x = float variable.
But the above code prints numbers after the decimal point, so I changed it to %d. But %d doesn't work with float variables..
What would be the best way to remove the decimal point from a float number? For instance if I have a float number .2546 I would like to be able to remove the dot and use just the number (int) 2546 for some calculations.
Maybe, convert to string than remove the first character from the string than convert the string back to an int?
If I have the following code:
long lSecondsSum = 8039;
double dNumDays = lSecondsSum / (24 * 3600);
I expect to get 0.093044 but for some reason I am getting dNumDays = 0.0000000000.
However, if I write the code as follows:
long lSecondsSum = 8039;
double dNumDays = lSecondsSum/24;
dNumDays = dNumDays/3600;
then I get correct dNumDays = 0.092777777777777778.
Also, how do I avoid all these floating point errors.
I am currently confused on how to get the highest and lowest number from a list of 7 numbers for a File Output. Lets say i have 165 19 654 816 654 987 324. How would i get the 987 for the highest and the 19 as the lowest? Those numbers are not fixed numbers, i need to be able to input any combination of numbers and still be able to get the highest and lowest numbers from the list of 7 numbers.

what is the effect on output of program of different numbers input to the int data type named seed*/
I am trying to create a simple interface on console to allow to input some values to some variables. For ex:
int main() {
double a = 1.5;
double b = 2.5;
double c = 3.5;
string x;
[Code] ....
However, I want these three to display at the same time (now they display one by one), and in the console window I can move the cursor between input place of a, b and c with "arrow key" of keyboard.
I need to make a program in which the output must be like:
I=0 J=1
I=0 J=2
I=0 J=3
I=0.2 J=1.2
I=0.2 J=2.2
I=0.2 J=3.2
.....
I=2 J=?
I=2 J=?
I=2 J=?
I am writing sample programs for graph problems like Dijkstra or Bellman-Ford algorithms. In Dijkstra, for instance, when I input my program a set of vertices and edges, ask to find shortest path from Vertex A to Vertex B, my program currently outputs shortest path from A to B. I want to display graph and have a visualization of the output generated. Is there a way to display nodes and connecting lines? What C++ classes would required achieve this?

What I'm focused on is reading in the first three numbers which I already have with fscanf and then reading in BUY TICKET with the digit afterwards. My problem is that I don't know how to reach that part of the file without scanning in something I don't want to. Also, how would I scan the number after scanning BUY TICKET? Would it be something like using %s and %d right afterwards?
So I have a double array, where I'm inputting float numbers to certain points in an array. Sometimes, the numbers that are printed out are completely different from what I put in.Here is the part of the code:
Code: .
while( token != NULL ) {
num = atof(token);
test[j][i] = num;
printf( "
%s, i is %d, j is %d
", token,i,j );
printf( "number is %f
value test of i,j is %f
[code]....
Why the float num prints out fine, but when put into an array becomes garbage?I'm taking string values from a csv file and turning them into floats, but no problems seem to crop up there.I reset i when appropriate and increment j when needed, so I don't think my problems are from incorrect array values (though they might be)

if we have a decimal number like c=3.46
And i want to set two number, a and b
now a= static_type<int>(c); so a=3;
and i want b= 46
which is the two numbers after the decimal how can I do that ? how can I set b = 46 ?
P.S: i do not know what c equals to. now it's two number after the floating point but it might be more or less
I need to implement a C++ program that asks the user for four floating-point numbers. The program should then calculate the average using two different functions, one value returning and one void. The program should output the average of the four numbers. For this program I need to use float instead of int for the types of variables. Below is a proto-type code that I am able to use to do this program.
#include <iostream>
using namespace std;
int sum(int,int);

I'm displaying a table of floating point numbers with setprecision(5). If the number is "1.25" it will display "1.2500" which is what I want. However, if the number is "0.25" it will display "0.25000"
How can I make numbers with a base number of zero display properly?

Well I understand the part it cannot store infinite numbers. but if you take a look at the output for example (since it is too long i just added some of the outputs)
//---------------------
for the value of : 001
1
//---------------------
for the value of : 002
0.5
//---------------------
for the value of : 003
0.3333333333333333148

if you look carefully at the value "5" and "10" results. it is awkwardly abnormal. which is something i couldnt understand. also it is the same with value "20", "25", "40", "50" and so on.
I have to complete a project that i want to read float numbers from keyboard and store them into an array of 10 elements.! Every time that a number stored into array i want to compare with previous one if they have +-10 difference .. I want to keep only 10 elements into my array so every time that i give value a[0] replace a[1], a[1] replace a[2],a[2] replace a[3]. . . .and a[10] deleted.. So when all elements of the array are similar with +-10 values print out the array.!
