Question

while(fgets(a,1024,pf)){
if(strcmp(a,b)){
printf(a);

i tried also
if(strcmp(a,b)!=0){

Answer 1

Are you aware that fgets() includes the newline in the string? (gets() doesn't but fgets() does.)

So if you are looking for a line containing only "foo" you'd have to set b to "foo\n".

Answer 2

Dam, your grammar is horrible.
