pointers-string search

[spveer]

I know an element in an array, say file1[10][10].

I know a pointer to one of the character in file1[10][10]
*****************

say if I have file1[10][10]="whereiam"

and I know a pointer to "i" in whereiam

I want to print "where"


I tried this, but have problem with these pointers.

*******************

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

int main()
{
	char *s[30];
	char ch, ch1[100][100];
	char file1[100][100], file2[100][100];
	int i=0, j, k, l, z=0, m, collect[100];
	char one_file[] = "one.txt";
	char two_list[] = "two.txt";
	char file_list[100][100];
	FILE *one,*two;
	clrscr();
	one = fopen(one_file,"r");   
	two = fopen(two_list, "w");
	while((ch=getc(one))!=EOF)
	{
		if(ch=='"') /*trying to search text between "..."*/
		{
			j=0;
			while((ch=getc(one))!='"')
			{
				file1[i][j]=ch;   /* text between "...." is stored*/
				fprintf(two, "%c", ch);
				j++;
			}
			file1[i][j]='\0';
			fputc('\n',two);
			i++;
		}
	}

	for(k=0;k<i;k++)  /*trying to search stringf in file1 with "text"*/
	{
		s[k]=strstr(file1[k],"text");
		if(s[k]!=NULL)
		{
			printf("\n\n%s",s[k]);
			collect[z]=k;
			z++;
		}
	}

/*if i have text "org.text#extra" , i get a pointer to "t" in org.text from above s[k]*/
/* i actually want org.text. I know pointer to "o" in org.text#extra, and i know pointer to "t". */
/*Now I am trying to read from pointer to "o" to pointer to "t"*/


/* to try this i implemented as below, this goes to infinite loop*/


	for(k=0;k<z;k++)
	{
		m=0;
		while((file1[collect[k]])!=(s[k]-1))
		{
			file2[k][m]=file1[k][m];
			m++;
			++*file1[collect[k]];
		}
		file2[k][m+1]=NULL;
	}
	for(k=0;k<z;k++)
	{
		printf("\n\nfinal strings = %s",file2[collect[k]]);
	}
	fclose(one);
	fclose(two);
	return(0);
}

2nd doubt:

Why am I not able to identify "#" in a string?

if "one" is a string,

while(ch=getc(one))!='#'), is never being satisfied, whereas I have "#" in the "one" string

1) 'ch' will never equal EOF, because EOF cannot fit in a char. Use an integer instead. Read the FAQ entry on EOF for more.

2) You should escape your quotation marks. This:

if(ch=='"')

Should really be:

if( ch == '\"' )

That'll get you started.
