C++ Please Help Killed by signal 8(SIGFPE).

[Robyy14]

Heya people i really would appreciate some help here..
The Program Works Just Fine At compiling but after like 1 second after ctrl + f10 to test it i get an error . I looked on google and it is something like Killed by signal 8(SIGFPE).

#include<cstdio>
#include<cctype>
#include<string>

using namespace std;

unsigned int i,l,c;
char txt[500];
FILE *infile;
FILE *outfile;
int main(){
    infile = fopen("text.in", "r");
    outfile = fopen("text.out", "w");

    while(!EOF){
          txt[1] = fgetc (infile);
          if (isalpha(txt[1])){
              c++;
              l+=strlen(txt);
          }
    }
    l=l/c;
    fprintf (infile, "%d", l);

fclose(infile);fclose(outfile);
}

Good luck with this doing anything meaningful. :icon_rolleyes:

>Killed by signal 8(SIGFPE)
Did you look up SIGFPE? The name means that a floating-point exception occurred, but the signal is actually thrown on general arithmetic errors. Normally I'd say to check your math, but your code is actually quite broken in other ways.

I could help more if you explained what the program is supposed to do.

So I get a Text For EX :
- I Love Pie Apple ;
And i Need to count the number of word and the number of letters then printf("%d" , number_letters/numbers_words);
