EOF and getchar() problem

**Aitra** · 06-20-2013

hi guys

I'm challenged to write a code for the following:

write a text up to 1000 characters, and get it back. the end of the text is detected though EOF on a new line or reaching 1000 characters.(EOF=ctr-Z on a new line)

I mainly have problem how to bring the EOF work probably. it doesn't react when I press ctrl-z directly . could you see the problem in the code?

Code:

int i;
    char Text[1000];

 printf("write the text:\n");
    gets(Text);

for(i=0;i<=1000;i++){

 Text[i]=getchar();                  //read every sign

 if((Text[i]=getchar()== '26' || i==1000)){   //26 is the ASCII code for ctrl-z

    puts(Text);

    }
}

    return EXIT_SUCCESS;
}

check two things: operator precedence of '==' vs '=' vs '||', and what value is '26' (hint, its not 26 decimal). best to put parentheses around each term you want to isolate in your expression.
run this snippet :

Code:

#include <stdio.h>

int main(int argc,char *argv[])
{
	int a = '26';

	printf("%d\n",a);
    return 0;
}

Read twice the post of dmh and then take a look here, in order to see how one uses EOF. It was from the very first occurrences of EOF in our ip course, so I think it can help.
