help please
1 char ch file name [25 2 FILE *fp, *fn; 3 char name [20] t lastword" 4 int i; 5 fp fopen words
.txt". "a" 7 fprintf (fp "%s An", name fclose (fp) 9 fopen words txt r" 10 printf The contents
of words .txt file are: ") 12 whiel (ch getc (fp) EOF) 13 14 printf "%c", ch 15 16 17 fclose
(fp) 18 fp fope ("f://words .txt "r"); n 19 fn fope ("f://lastword .txt", "w"); n 20 while fgets
(fi name, 25 fp NULL) le 21 print %s fi le name 22 if(strcmp name, file name) 30) 23 24 fprintf
fn Ann file name 25 26 27 f close (fp) 28 fclose (fn)
Solution
//Use the following code which has no compilation errors
#include <stdio.h>
int main(void)
{
char ch,file_name[25];
FILE *fp,*fn;
char name[20]={"lastword"};
int i;
fp=fopen("words.txt","a");
fprintf(fp,"%s ",name);
fclose(fp);

2.
fopen("words.txt","r");
printf("the contents of words.txt file are: ");
while((ch=getc(fp)!=EOF))
{
fprintf("%c",ch);
}
fclose(fp);
fp=fopen("f://words.txt","r");
fn=fopen("f://lastword.txt","w");
while((fgets(file_name,25,fp))!=NULL)
{
printf("%s ",file_name);
if(strcmp(name,file_name)==0)
{
fprintf(fn,"%s/n",file_name);
}
}
fclose(fp);
fclose(fn);
}
