Why doesn't this (relatively simple) code work? (aka, why does my computer hate me?)
Hey, I'm building a small program.
This is just the first part, which tries to scan for a multi-digit number and put it in some variable.
Problem is, for some reason, it wouldn't calculate simple things (sometimes even doing 10^3, 10^1 and 10^0 just fine, but giving 99 as a result of 10^2. Yes, "wtf" did come to mind at this point).
Is this a problem with the code or it is my computer trying to annoy it's wretched master?
Help would be REALLY appreciated.
Here's the code:
Code:
#include <stdio.h>
#include <conio.h>
#include <math.h>
void main()
{
int y=1,ss=0,fatty;
char ch=0;
char num[4]={{0,0,0,0}};
char number=0;
int tester;
printf("Enter your number. When you're done, press esc.");
while (y<2)
{
ch=getch();
if (ch==27)
y = 2;
else
{
if (ch > 47 && ch < 58)
{
ch = ch - 48;
printf("%d\n",ch);
num[ss]=ch;
ss++;
}
}
}
ss--;
for ( fatty = 0 ; fatty <= ss ; fatty++ )
{
tester = pow(10,ss-fatty);
printf("\n%d,%d,%d,%d",ss,ss-fatty,num[ss-fatty],pow(10,num[ss-fatty]));
getch();
number = number + num[ss-fatty] * pow(10,num[ss-fatty]) ;
printf("\n%lf",number);
}
printf("Your number is: %lf",number);
getch();
}
This version is closer to working, though it uses %d when trying to printf a double variable, instead of %lf (which I think is correct).
Code:
#include <stdio.h>
#include <conio.h>
#include <math.h>
void main()
{
int y=1,ss=0,fatty;
char ch=0;
char num[4]={{0,0,0,0}};
char number=0;
int tester;
printf("Enter your number. When you're done, press esc.");
while (y<2)
{
ch=getch();
if (ch==27)
y = 2;
else
{
ch = ch - 48;
printf("%d\n",ch);
num[ss]=ch;
ss++;
}
}
ss--;
for ( fatty = 0 ; fatty <= ss ; fatty++ )
{
tester = pow(10,ss-fatty);
printf("%d,%d,%d,%d",ss,ss-fatty,num[ss-fatty],tester);
getch();
number = number + num[ss-fatty] * tester ;
printf("\n%d",number);
}
printf("Your number is: %lf",number);
getch();
}
