C++ :: How To Link A Switch Statement To A If / Else

Aug 8, 2014

The sample output of this program would be:

Please select:
1 - Year
2 - Day
3 - Month
Input choice: 1
Input Number: 2
I'm a Sophomore!

Please select:
1 - Year
2 - Day
3 - Month
Input choice: 2
Input Number: 2
It's Tuesday.

Please select:
1 - Year
2 - Day
3 - Month
Input choice: 3
Input Number: 2
February. Heart's month!

Here is my code, I only typed the Year(levels) yet because when I tried to input 2(day) and 3(month) for the Input choice and after that, Inputting a number to 1-4 would yield the same result to case 1's year levels.

#include <stdio.h>
#include <conio.h>
using namespace std;

[Code].....

how to link the case 2 to days and case 3 to months?

C/C++ :: Display Data From File Into 2D Array - Print Closest Bmi From Data

Mar 28, 2015

#include <iostream>
#include <fstream>
using namespace std;
int main() {
int r = 0;
int c = 0;
int num[17][15] = { 0 };
[Code] ...

// Here is my code for displaying the data from the text file into a 2d array and height next to it, but I am not able to diaplay the height from 60 to 76 next to the row of the 2d array, as shown in the table below. This is my program:

Recently the health authorities have listed a new way to calculate the body mass index (BMI) of an individual.
Values of 20 – 24 are classified as normal, 25-29 as overweight, and 30-34 as heavy.

The table below is a portion of a typical BMI table.

BMI:202122232425262728293031323334
Height:
60102108113118123128133138143149154159164169174
61106111116122127132138143148153159164169175180
.
.
.

MY task is to write a program that does the following things:

1.Produce the table by reading in the data from bmi.txt (on Moodle) into a 2-D array.

2. Display the table neatly on the screen, with row and column headings. The BMI should go from 20 to 34. The height should go from 60 to 76 inches.

3. Prompt the use for their height (in inches) and their weight.

4. Make the program print the closest BMI.

If their weight is lower than the values on the table, use 20 as the BMI.
If their weight is higher than the values on the table, use 34 as the BMI.

5.Loop the program so the user can find more BMI’s.

C++ :: Switch Statement Falling Through All Cases

Jan 16, 2014

I was getting errors and I looked into the error and it told me to fix it by adding Code: { } in my case statements. I did, it compiled but fell through the whole thing. Lets say I enter 1, it outputs the was not found 5 times in a row.

Code:
void addressbook::EditNameOrDate() {
std::cout << "Enter 1 to Edit the contacts First Name: " << "
";
std::cout << "Enter 2 to Edit the contacts Last Name: " << "
";
std::cout << "Enter 3 to Edit the contacts Street Address: " << "

C :: Add Little Extra To Switch Statement Assignment

Jun 12, 2013

I pretty much got the assignment done. All it asked for was that you make a C program that displays which manufacturer owned a disk drive based on the code entered. Pretty simple. Just enter 1, 2, 3, or 4 and get the associated manufacturer. Though I am trying to implement an error messege to it for any interger that isn't 1-4.

Code: #include <stdio.h>
int main()
{

[Code]...

o errors are given and it works fine as long as you enter 1-4, but when you enter any other didgit it just stops the program without any messeges.

C :: Switch Case Statement Does Not Execute

Feb 11, 2013

Im going through a C tutorial and im going to create a Database as part of the course. Im just in the very beginning of the project so its a very simple program so far.

Code:

#include<stdio.h>
main(){
/*Variabler for att lagra information om skiva*/
char title[200];
char artist[100];
int tracks;
int price;

[Code] ....

The first switch case statement takes me to the menu of choice, 1 or 2. However, chosing menu option one and trying to input a title or artist name, the program crashes.

Next, going into menu option 2 and then trying to print out, for example, title nothing happend. The process just ends.

Again, im sure this simple prototype is full of errors ....

C++ ::  Switch Statement - Summing Items

Nov 6, 2014

I'm creating a program that is combining functions to show a menu to a user then the user picks numbered items which results in the totalling of a bill for them.

Where I'm stuck is after they're entered their selections, how to take them and sum them up. I've been trying with a switch statement, but I'm not sure if this is the right method. Is it even possible to sum separate cases of a switch statement together? Below is the code I've gotten so far:

#include <iostream>
#include <iomanip>
using namespace std;
void showMenu ();
void showBill (double, double, float, double);
void changeDue (double, int);

[Code] ....

C++ :: Switch Statement Without Writing Each Case

May 28, 2014

I was just wondering if a switch statement can work without writing each case, for instance:

{ int age;
age=18;
while (age!=0) {
cout<<"Enter age :"<<endl;
cin>>age;
switch (age) {

[Code] ....

It works only for values specifically entered as a case, for instance if you enter 5 or 15 , it says bicycle, but if you enter anything inbetween it goes to default. Same with 18 and 100. It can't possibly be that you have to enter

case 19:
case 20:
case 21:
case 22:.......up to 100 to include all possible cases.

C++ :: Passing A Function Value Into Switch Statement

Feb 23, 2015

I had it working with the switch statement within the function, but later instructions said that it must be inside of main. I just get a loop no matter what I do. 5 needs to exit the program, all the other selections need to display the corresponding cout statements. I've done something to where the inputs are not actually passing into the switch statement. If any value other than 1-5 is put in, the menu should repeat and prompt the user again.

#include <iostream>
#include <cmath>
#include <cstdlib>

using namespace std;
int call_menu(int selection);
double kilo_m(double miles);

C/C++ :: Algorithmic Complexity Of Switch Statement

Feb 14, 2014

Suppose you have a switch statement defined like:

switch (parameter) {
case ONE:
case TWO:
// ... other n-2 cases
case N:
doSomething();
break;
default:
somethingElse();
break;
}

What is the complexity of the doSomething()? Is it still equal to the complexity of doSomething() , or the complexity of doSomething() plus the number of case statements? In other words, does the number of case statements a conditional piece of code has count towards the complexity?

C/C++ :: How To Make Switch Statement Work

Feb 26, 2014

The program i am trying to make is for practice of using switch. the idea is the user enters a number and the program will print a day of the week corresponding to said number.

the statement is not complete with all cases yet, but i dont want to write all of it until i am sure of it being correct.

errors when compiling (gcc) are as follows

1 warning and 3 errors generated.

C/C++ :: Switch Statement Not Working In Functions

Nov 22, 2014

The switch statement is giving me trouble. Worked fine in the main, but when I had to put it in separate functions per my professor, I had several issues. I guessing I am not calling the function correctly. Our group worked on it but could not find a solution to fix the switch statement.

#include <iostream>
#include <iomanip>
#include <fstream>
#include <conio.h>
using namespace std;
//function prototypes
int menu(); //function to show main menu
void Seating_Chart(); //function to show seating chart

C++ :: Returning Operator To Switch Statement

Sep 5, 2012

I planned to build a four function fraction calculator adding some advance feature like error checking in input so that user are prompted to input correct numbers and operator.

I created a separate member function getOper() function for getting correct operator and getFrac() function for getting correct fraction.

My intention was just to get correct operator from getOper() function and returning the operator to switch in main() function to do specific calculation. But, i don't know why i am getting repeatedly error when inputting correct operator while debugging program.

Here's my complete code.

Code:
#include <iostream>
using namespace std;
char c;
class fraction {
private :
int num;

[Code] .....

I checked the program again by assigning char to variable "oper" and function "getOper(). But, result is same.And again i changed variable "oper" to default keyword operator, but, it really didn't worked as expected.
