compiler disappears

Hello

I am trying to find a string in a text file.
The program is working fine when I search small text files.

But the turbo C compiler is just disappearing when the text file to be searched is large.

Why is this happening?

How can I fix it?

Code:

---

#include <stdio.h>
#include <string.h>

int main()
{
        int ch,i=0,j=0,k;
        char store[300][100];
        char one_file[] = "one.txt";
        char two_list[] = "two.txt";
        FILE *one,*two;
        clrscr();
        one = fopen(one_file,"r");
        two = fopen(two_list, "w");
        while((ch=getc(one))!=EOF)
        {
                if(ch=='s')
                {
                        if((ch=getc(one))=='r')
                                if((ch=getc(one))=='c')
                                        if((ch=getc(one))=='\=')
                                                if((ch=getc(one))=='\"')
                                                {
                                                        j=0;
                                                        while((ch=getc(one))!='\"')
                                                        {
                                                                store[i][j]=ch;
                                                                fprintf(two, "%c",ch);
                                                                j++;
                                                        }
                                                store[i][j]='\0';
                                                fputc('\n',two);
                                                i++;
                                                }
                }
        }
        for(k=0;k<i;k++)
                printf("string[%d]=%s\n",k,store[k]);
        fclose(one);
        fclose(two);
        return(0);
}

What the heck to you mean by "But the turbo C compiler is just disappearing when the text file to be searched is large."?

Sorry,
I mean, when I run the program with a large text file to be searched, it doesnt work out.

But I am able to run the program for small text files to be searched.

Take a look at my reformatted version and see if this is what you want (logically, this is how the program executes):

Code:

---

#include <stdio.h>
#include <string.h>

int main() {
    int ch,i=0,j=0,k;
    char store[300][100];
    char one_file[] = "one.txt";
    char two_list[] = "two.txt";
    FILE *one,*two;
//    clrscr(); // not available on my machine
    one = fopen(one_file,"r");
    two = fopen(two_list, "w");
    while((ch=getc(one))!=EOF) {
        if(ch=='s') {
            if((ch=getc(one))=='r'){
                if((ch=getc(one))=='c'){
                    if((ch=getc(one))=='\='){//warning C4129: '=' : unrecognized character escape sequence
                        if((ch=getc(one))=='\"') {
                            j=0;
                            while((ch=getc(one))!='\"') {
                                store[i][j]=ch;
                                fprintf(two, "%c",ch);
                                j++;
                            }//end while((ch=getc(one))!='\"')
                            store[i][j]='\0';
                            fputc('\n',two);
                            i++;
                        }//end if((ch=getc(one))=='\"')
                    }//end if((ch=getc(one))=='\=')
                }//end if((ch=getc(one))=='c')
            }//end if((ch=getc(one))=='r')
        }//end if(ch=='s')
    }//end while((ch=getc(one))!=EOF)
    for(k=0;k<i;k++){
        printf("string[%d]=%s\n",k,store[k]);
    }
    fclose(one);
    fclose(two);
    return(0);
}

It is a very bad idea to have multiple lines in a statement and not surround them by braces (many people think you should always use braces, even for single line statements) even when the parser will handle things according to your expectations as any tiny change to the code can wind up changing the logical flow of the code. Also note that I got a compiler warning, this is almost certainly an error in your program. It is also a bad idea to ignore warnings as they are almost always pointing out bugs (compiler writers are some pretty smart dewds, it is a bad idea to second guess them).

With your large file are you finding more than 300 strings such that you are overrunning your store array? Something like this would be safer.

Code:

---

if ( ++i >= sizeof store / sizeof *store )
{
  break; /* maybe print a message saying the array is full */
}

---

You may also want to consider the same sort of thing with the string length.

now i get it, thanks. Yes the array is full!!
