c - while compiling below code am getting segmentation fault can you spot me the error for me -
#include<stdio.h> #include<ctype.h> void main() { file *fp1,*fp2,*fp3; char a[100],b; int i=0,j=0; fp1=fopen("names.txt","r"); fp2=fopen("names.txt","w"); i=0; { b=fgetc(fp1); b=toupper(b); a[i]=b; i++; } while(b!=eof); i=0; { fputc(a[i],fp2); i++; }while(a[i]!=eof); fclose(fp1); fclose(fp2); fclose(fp3); }
am getting segmentation fault while compiling code can u plzz me spotting error error like"line 2:segmentation fault "
you need learn how debug. either learn how use debugger, or if haven't got patience, put debug prints in code see how far getting. example:
fprintf(stderr, "%d\n", i);
that tell something. find error pretty quickly.
my guesses are:
- your file bigger 100 characters.
- b should int , should not store in array.
- the second loop should not end-of-file, should use count of number of characters read.
- you closing fp3 haven't opened it.
but again, basic stuff. need learn basic debugging.
