copied!<p>You can use the following code to do it.</p> <p>Your problems were that you weren't checking the return from <code>fscanf</code> and that you weren't actually reading the newline (so the next time you read, you wouldn't go to the next line).</p> <pre><code>#include<stdio.h> #include<string.h> #include<stdlib.h> int main (void) { FILE *fp; int x; fp=fopen("mydata.txt","r"); if(fp==NULL) { perror("Error while opening"); exit(0); } char *s=(char*)malloc(100); while(!feof(fp)) { x = fscanf(fp,"%[^\n]",s); fgetc(fp); if (x == 1) printf("%s\n",s); } return 0; } </code></pre> <p>However, if all you're after is the ability to input and process lines, <code>fgets</code> is a better solution than <code>fscanf</code> since there's no chance of buffer overflow:</p> <pre><code>#include <stdio.h> #include <string.h> #define OK 0 #define NO_INPUT 1 #define TOO_LONG 2 static int getLine (char *prmpt, char *buff, size_t sz) { int ch, extra; // Get line with buffer overrun protection. if (prmpt != NULL) { printf ("%s", prmpt); fflush (stdout); } if (fgets (buff, sz, stdin) == NULL) return NO_INPUT; // If it was too long, there'll be no newline. In that case, we flush // to end of line so that excess doesn't affect the next call. if (buff[strlen(buff)-1] != '\n') { extra = 0; while (((ch = getchar()) != '\n') && (ch != EOF)) extra = 1; return (extra == 1) ? TOO_LONG : OK; } // Otherwise remove newline and give string back to caller. buff[strlen(buff)-1] = '\0'; return OK; } </code></pre> <p> </p> <pre><code>// Test program for getLine(). int main (void) { int rc; char buff[10]; rc = getLine ("Enter string> ", buff, sizeof(buff)); if (rc == NO_INPUT) { printf ("No input\n"); return 1; } if (rc == TOO_LONG) { printf ("Input too long\n"); return 1; } printf ("OK [%s]\n", buff); return 0; } </code></pre> <p>Sample runs with 'hello', <kbd>CTRL</kbd><kbd>D</kbd>, and a string that's too big:</p> <pre><code>pax> ./qq Enter string> hello OK [hello] pax> ./qq Enter string> No input pax> ./qq Enter string> dfgdfgjdjgdfhggh Input too long pax> _ </code></pre>
