C/C++ :: If Statement Comparing Array To Scanf Input
Oct 25, 2014The issue that I'm having is that when I run this part of the code it seems to enter the if statement and set it to 0 when comparing the array to the input.
What I want it to do is to search the array for the grade, set it to zero, and then exit the loop in case there are any repeat grades. It always sets the first number to 0 and then exits.
//Below is the prototyping for the array
int grades[14] = {60,50,50,20,75,90,0,0,0,0,0,0,0,0};
//There is some code between here, but it is probably not relevant so I didn't post it.
printf("Enter the grade that you want to remove. Press Enter after each input.");
printf("Enter 0 to exit: ");
[Code] ....
I didn't mean to leave the "prototyping" part in the code. I was initially going to put the function prototypes in there, but decided it wasn't necessary for the question.
C/C++ :: 2D Array - Switch Statement To Move Char
Mar 25, 2014Just making typical console game where hero moves with w a s d.
However, in my code, while a and w work (minusing), s and d dont work (adding). I have used a switch statement to change the char position of the hero based on kbhit.When you hit s or d, the buttons that add 1 to the 2nd dimension of the array, the screen goes crazy!

Sep 22, 2013This while statement is not cooperating and I am not really sure why. I tried to say while not equal to true and later false, but both produce a never ending loop.

C++ :: If Statement In For Loop
Oct 5, 2013I seem to be having a bit of problem with my if statements in a for loop.
My code involves asking the user for the name of an element (chemistry), searching a text file line by line for an element that matches the input, and outputting other information regarding that element.
One line of the text file looks like this: Helium,He,2,4.00
I've tried running the code without the if loop and it outputs normally (If I ask it to output elementname[0] it will output the first element Hydrogen, which is correct.) but I am not sure what goes wrong when I add the if statement. For some reason, it always follows the "else" statement (It always outputs Invalid search even when I input the right elements).
const int ELEMENTS = 118; //number of elements
ifstream File;
string elementname[ELEMENTS], atomicsymbol[ELEMENTS], atomicnumber[ELEMENTS], atomicmass[ELEMENTS];
string elemname, atomsym, atomnum, atommass;
string search;

View 5 Replies View RelatedC# :: Using If Statement And Loops?
Nov 28, 2014I just want to say that I just started learning the language and this is my very first shot at writing a simple program that is not "Hello World" So I recently learnt the basics of the if statement and how to loop in a console application, here's what it looks like:
namespace Testing_IF_Statement
{
class Program
{
[Code].....
And again, this is just what I wrote in a few minutes without putting any thought into it.
Questions:
1)I have heard that the way I'm looping by using the goto statement is considered quite ancient, why is this and how else could I loop the program?
2)I declared a as an integer and asked the user to type 1,2,3,4 to perform mathematical functions, but when I tried declaring a as a string and searching if a == "PLUS" etc it would throw an error. Is there any mistake in how I approached this?
3)I know this is a bit premature to ask, but instead of writing _________ in the console to separate the loop is there any professional way to add a separator?
4)In general how can I improve the code?

C++ :: If Statement Multiplication By Zero
Mar 28, 2013I want to set an integer to zero when it easy equal to another integer, but it seems that the program for some reason won't set the integer to zero. Here is the example of that code:
#include <iostream>
using namespace std;
int main () {
int n = 2;
int r = 2;
if(n==r)
n++;
r*0;
cout << " n is " << n << endl;
cout << " r is " << r << endl;
}
What am I doing wrong, it should say that "n is 3" and "r is 0".

C++ :: Getting Error Using Enum In If Statement?

I also decided to add a feature which allows them to select how many tries they would like to guess the number. I tried to make "tries" type an enum so if the user could not pick an invalid number but for some reason i cannot use it in an if statement.

Jan 11, 2014If i declare a function as a void function. But for testing purpose if i use a return statement in the function definition. i have tested and found that the function does not return and executes the entire function. How does the function not return even if a return statement is available? Does the compiler removes this return statement or how it is?
View 2 Replies View RelatedC :: If Statement With Multiple Conditions
Feb 26, 2013I have tried writing a code and come across an issue where I'm not getting the desired result. It is to design a program that tells whether gas emissions from a car are too high, or permissible. The instructions are to design a code where there are four possible choices of pollutant, whether the emitted pollutant ratio is greater or less then a certain value, and the mileage on the car. All of these are supposed to determine whether the emissions are permissible or not, which would be displayed with printf. (The actual conditions of the assignment are described perfectly by the code below, so I didn't think it would be necessary to write it out. The problem is that I'm getting a logical error.) Here's the code:
Code:
#include <stdio.h>
int main() {
int poln, odr;
double gpm;
printf ("(1) Carbon Monoxide
[Code] ....
My error is that the program will proceed with the first four if/else statements, but once the 'poln' value changes to something other then one, it will not display the expected quotation.
