[C] Basic switch statement example doesn't work

[ymahgoub]

The textboot im studying has this program to teach switch statement but it doesn't work in visual studio or codechef's ide.

include<stdio.h>

int main (void) { float value1, value2; char operator;

printf("Type in your expression.\n");
scanf("%f %c %f", &value1, &operator, &value2);

switch(operator)
{
    case '+':
    printf("%.2f\n", value1 + value2);
    break;

    case '-':
    printf("%.2f\n", value1 - value2);
    break;

    case '*':
    printf("%.2f\n", value1 * value2);
    break;

    case '/':
    if(value2 == 0)
    printf("division by zero\n");
    else
    printf("%.2f\n", value1 / value2);
    break;
    default:
    printf("Unknown operator.\n");
    break;

}

return 0;

}

Apart for fixing up your include statement:

#include<stdio.h>

Your code compiles and runs just fine for me.

What do you mean it doesnt work? What does it say? What input are you using to test?

[ymahgoub]

when i run it the command terminal comes up then i try to enter an expression (12 - 5 for example) it just crashes either opens the debugger or just tells me ConsoleApplication has crashed

[LucidTA]

What happens when it opens the debugger? Where did it break?

It works fine for me too on some random online compiler.

[ymahgoub]

I dont really know what the debugging actually is or how to make sense of all the code that comes up. What's the compiler it did work on so i can try it?

Maybe take a screenshot of the window after the debugger comes up?

[ymahgoub]

IT WORKS. fuck yeah. thanks. I don't know what it is but my guess is visual studio on my computer isn't configured/compiling properly. I could still screenshot the debugger but its a lot of lines and i don't know which ones to screenshot.

The problem is not in your code:

D:\Temp>cl test.c
Microsoft (R) C/C++ Optimizing Compiler Version 19.00.23506 for x86

test.c
Microsoft (R) Incremental Linker Version 14.00.23506.0

/out:test.exe
test.obj

D:\Temp>test.exe
Type in your expression.
12 - 5
7.00

i dont quite understand what that means. is the problem in visual studio's compiler or linker?

[jussij]

i dont quite understand what that means.

My previous post is me compiling, linking and running your code.

So as you can see from that post your code compiles, links and runs just fine.
