I am trying to read a file and look for some words. If I know the work I am searching in advance would it be possible to store it and compare it with what I read from the file using strcmp in c? for example: if I am reading a c source file and if I see the word void then I print it back as VOID. so would this work: char myword[] = "void"; read from the file *f while (strcmp (myword,*f) != 0) do cap here. would this work? or how can I do it in C? Thanks!

Thanks Santanu Sen the strupr(word) did not work, I am using gcc. is there a lib to include. Thanks AD

Yeah, there is no equivalent function in gcc. why not write the function ourselves? char *strupr(char *); /*Declaration*/ char *strupr(char *word) { int i; for(i = 0; i < strlen(word); i++) if(word[i] >= 'a' && word[i] <= 'z') word[i] += ('A' - 'a'); return (word); } Santanu Sen National Institute of Technology Durgapur India
