deleting a word from a file, si

I am writing a program that would delete the word entered from the keyboard from a text file (if it is there). After launch, the remaining words in the btest.txt file become one large line. How can you make the words in the output file be located in the same way as in the input file, only without the already deleted word?

#include <stdio.h> #include <string.h> int main(void) { char buf[512]; char word[128]; FILE *in_file = fopen("C:\\atest.txt", "r"); FILE *out_file = fopen("C:\\btest.txt", "w"); if(!in_file || !out_file) return -1; printf("Input word: "); scanf("%127s", word); while(!feof(in_file)) { fscanf(in_file, "%511s", buf); if(!strcmp(buf, word) ) continue; fprintf(out_file, "%s", buf); } fclose(in_file); fclose(out_file); }
