Here the code I have so far:

#include <stdio.h>
#include <math.h>

void main()
{
double comprLoad;
double comprStress;
double d,area;
char type[20];
const double PI= 3.14;

printf("Enter material type: ");
scanf("%s",type);
printf("Enter compression load: ");
scanf("%lf",&comprLoad);


comprStress = 25000;
area =comprLoad/comprStress;
d=2*sqrt(area/PI);


printf("\n\nType of the material: %s\n",type);
printf("Compression Load: %.2lf\n",comprLoad);
printf("Allowable stress: %.2lf\n",comprStress);
printf("Diameter: %.2lf",d);


comprStress=15000;
area =comprLoad/comprStress;
d=2*sqrt(area/PI);

printf("\n\nAllowable stress: %.2lf\n",comprStress);
printf("Diameter: %.2lf",d);

comprStress=20000;
area =comprLoad/comprStress;
d=2*sqrt(area/PI);

printf("\n\nAllowable stress: %.2lf\n",comprStress);
printf("Diameter: %.2lf",d);
getchar ();
return;
}

For some reason it exits prior to performing any of the calculations. Not sure why. Any and aall help is greatly appreciated. It will allow me to enter the material type and the compression load but quickly exits after that.

What the heck am I doing wrong?

I copied your code into a new CodeBlocks console project. It displayed everything as expected:


Enter material type: test
Enter compression load: 20


Type of the material: test
Compression Load: 20.00
Allowable stress: 25000.00
Diameter: 0.03

Allowable stress: 15000.00
Diameter: 0.04

Allowable stress: 20000.00
Diameter: 0.04
Process returned 0 (0x0) execution time : 4.735 s
Press any key to continue.

Im trying to get this to work in Visio......any idea why it wouldnt work there?

[lespauled]

Visio? or Visual Studio?

[devilnewt]

Oh hell my bad, visual studio.....something doesnt seem right about the program

Try either turning precompiled headers off or you can #include <stdafx.h> . I'm just assuming here since lespauled said it ran fine.

[DarkLordofthePenguins]

At what point does it exit?

stdafx.h is not a standard header. I've been working with C for years and have become familiar with the C Standard Library, the POSIX API, and to some extent the Windows API, and I have never even heard of stdafx.h. I'm guessing it's a component of some specific framework, and only works for that framework. In any case, you shouldn't use it.

stdafx.h is a VS thingy, you should include it.

If you're using Visual Studio, put a breakpoint on the first line, and hit F10 to go step by step through the program.

But this works in Visual Studio:

#include "stdafx.h"
#include <stdio.h>
#include <math.h>
#include <iostream>

void main()
{
double comprLoad;
double comprStress;
double d,area;
char type[20];
const double PI= 3.14;

printf("Enter material type: ");
scanf("%s",type);
printf("Enter compression load: ");
scanf("%lf",&comprLoad);


comprStress = 25000;
area =comprLoad/comprStress;
d=2*sqrt(area/PI);


printf("\n\nType of the material: %s\n",type);
printf("Compression Load: %.2lf\n",comprLoad);
printf("Allowable stress: %.2lf\n",comprStress);
printf("Diameter: %.2lf",d);


comprStress=15000;
area =comprLoad/comprStress;
d=2*sqrt(area/PI);

printf("\n\nAllowable stress: %.2lf\n",comprStress);
printf("Diameter: %.2lf",d);

comprStress=20000;
area =comprLoad/comprStress;
d=2*sqrt(area/PI);

printf("\n\nAllowable stress: %.2lf\n",comprStress);
printf("Diameter: %.2lf",d);

std::getchar();

return;
}

If it exits early, It possibly crashed. Can you enter in debug mode so you can see which line number it crashes?
