Thread: Floating point exception

My program is compiling correctly and I'm getting output also but out of 10 values only 9 are getting printed (have used a loop)and a floationg point exception (core dumped) message is getting printed. please help me.

Welcome to the forum, Jayalakshmi!

I'll take a wild guess and suggest you are trying to print outside the bounds of the array you have (or linked list).

But no one can really help you without seeing the code - so post it up, and please use the code tags (in the advanced editor, click on that icon after highlighting your code).

That will make your code easier (FAR easier) to read.

Code:

#include<stdio.h>
#include<math.h>
int i,j,k,t,count,loc,min_dist=100;
FILE *fp;
char str1[10],str2[10],str3[10];
int noc,not,u[50],total[50],capacity_c[150],capacity_t[150],bal[150],a[30][10],b[150][10],so[150][150],dist[50][150];
void main(int argc,char* argv[])
{
    
    if(argc!=2)
      exit(0);
    else
          fp= fopen(argv[1],"r");
          fscanf(fp,"%s", str1);
          fscanf(fp,"%s",str2);
          fscanf(fp,"%s", str3);
          fscanf(fp,"%d",&noc);
          //printf("%s,%d\n",str1,noc);
    for(i=0;i<noc;i++)
          for(j=0;j<3;j++)
               fscanf(fp,"%d",&a[i][j]);

    for(i=0;i<noc;i++)
          for(j=0;j<3;j++)
               printf("%d\n",a[i][j]);
           fscanf(fp,"%s", str1);
       fscanf(fp,"%s",str2);
       fscanf(fp,"%s", str3);
       fscanf(fp,"%d",&not);
       //printf("%s,%d\n",str1,not);
    for(i=0;i<not;i++)
          for(j=0;j<3;j++)
               fscanf(fp,"%d",&b[i][j]);
    
    for(i=0;i<not;i++)
          for(j=0;j<3;j++)
               printf("%d\n",b[i][j]);
    
    for(i=0;i<noc;i++)
          for(j=0;j<not;j++) 
          {
             dist[i][j]=sqrt(pow(b[j][0]-a[i][0],(double)2)+pow(b[j][1]-a[i][1],(double)2));
             //printf("%d\t",dist[i][j]);
          }
        for(i=0;i<noc;i++)
        for(j=0;j<not;j++)
           sol[i][j]=0;
    for(i=0;i<noc;i++)
          total[i]=0;
    for(i=0;i<noc;i++)
    {
          capacity_c[i]=a[i][2];
         // printf("%d\n",capacity_c[i]);
    }
    for(j=0;j<not;j++)
    {
        capacity_t[j]=b[j][2];
       // printf("%d\n",capacity_t[j]);
    }
    for(i=0;i<not;i++)
 u[i]=i;
count=not;
    for(i=0;i<not;i++)
    {
        min_dist=100;
        k=rand()%count;
        printf("\n%d\t",k);
        t=u[k];
        u[k]=u[count--];
  for(i=0;i<noc;i++)
      {
       printf("%d\t",dist[i][t]);
        if(capacity_c[i]>=apacity_t[t])
        {
           if(dist[i][t]<min_dist)
   min_dist=dist[i][t];
           loc=i;
          }
  
    }
    sol[loc][t]=t;
    total[loc]+=1;
    capacity_c[loc]=capacity_c[loc]-capacity_t[t];
    printf("\t%d\t%d\t%d\t%d\t%d\t%d",sol[loc][t],total[loc],capacity_t[t],capacity_c[loc],min_dist,loc);
      
    }
}

Here is my code
it is a terminal assignment problem. my input is a file i'm passing it using commnad line
my input file is:
Number of concentrators: 3
19 76 12
50 30 14
23 79 13
Number of terminals: 10
54 28 5
28 75 4
84 44 4
67 17 2
90 41 3
68 67 1
24 79 3
38 59 4
27 86 5
07 76 4

help me.

You are now the third or fourth poster within the last hours who claims her/his posted code compiles correctly although that's not true:

Code:

$ gcc -ggdb3 -Wall -Wextra -o test test.c
test.c:7:6: warning: return type of ‘main’ is not ‘int’ [-Wmain]
test.c: In function ‘main’:
test.c:11:7: warning: implicit declaration of function ‘exit’ [-Wimplicit-function-declaration]
test.c:11:7: warning: incompatible implicit declaration of built-in function ‘exit’ [enabled by default]
