Answer 2

You can say that it is a like=up vote and dislike=down vote for a comment or a post or a question

Answer 3

You're welcome 😊

Answer 4

Oh, thanks man. You have been helping all the way... Thanks

Answer 5

There are two mistakes in code:
(1.)The 'switch' case statement only works with 'constant expressions' not 'conditional statements'.
(2.)Missing ';' in line 24.

Bonous advice:-
LEARN TO READ THE ERROR MESSAGES ..as they tell all the errors precisely and also the line number in which it exists.....

Answer 6

Use if else much better

Answer 7

Use semicolon after break.only constant values are used in switch case.

Answer 8

You can't use expressions like x>0 or x<0 in switch..case sentence but you can use ranges like saying:
int x=8;
switch (x){
case 0 ... 10:
cout<<x<<endl;
break;
//outputs 8.
So that's the first error & the second one is that you forgot to put ' ; ' after every break. And to correct the program i advice you to use if & if else statements it will be easier to finish your program successfully.
I hope i explained it well.

Thanks a lot...

Can I ask a question? What is the voting for this? Other than that, it is possible to make a scientific calculator using C++ but it takes a lot of lines right?

Answer 11

Yes you can make scientific calculator " scientific not basic" but it will need you to be an advanced c++ programmer but you can make a basic calculator that use +,-,/,* operators using if & if else statements it will be good if you make it, you can try 😃.

Answer 12

You can also made simple calculator using switch

Answer 13

oh
Okok, I'll try... Actually previously, I tried making a basic calculator with the operators but I also tried with squaring a number.
I tried programming it before, then I only came to try this website. It took a lot of line. But now I know switch, it will be easier...

Answer 14

What is the voting thing at the top left corner of the screen for?

Put ; in break statements and don't put case <=0:
//Case ×
put case Interger<=0:
//Case ✓

Answer 18

Use easily use if and else in place of switch statement

#include <iostream>

using namespace std;

int main()
{
int integer;
cout << "Input a number: " ;
cin >> integer;
cout<<integer<<endl;
if(integer<0)
{
cout << "This is a negative number.\n";
cout << "Your number is: " << integer << endl;

}
else if(integer>0)
{
cout << "This is a positive number.\n";
cout << "Your number is: " << integer << endl;

}
else if(integer==0)
{

cout << "The number is a zero.\n";

}
else
{

cout << "This is not even a number..." << endl;

}

return 0;
}

Answer 19

Switch statements are only for constant inputs
Like input is 7
So case 7:
You cannot place any conditional statements in switch statements
It is better to use if else statements in this type of program
Hope to make a change....
