Hey guys,
Ive been working through this book to learn C and when i compile one of the examples, the command window comes up, and i can type in it, but when i press enter, nothing happens, it just makes a new line, and the printf command in main() doesnt ever seem to execute. Please could anyone shine a light on why it may not be running properly? Any help would be greatly appreciated.
Thanks
Code:
// Read Line.cpp : Defines the entry point for the console application.
//
#include <stdio.h>
#define MAXLINE 1000 /* maximum input line size */
int getline(char line[], int maxline);
void copy(char to[], char from[]);
/*print longest input line */
main()
{
int len; /* current line legnth*/
int max; /* maximum length so far */
char line[MAXLINE]; /* current input line */
char longest[MAXLINE]; /* longest line saved here */
max = 0;
while ((len = getline(line, MAXLINE)) > 0)
if (len > max) {
max = len;
copy(longest, line);
}
if (max > 0) /* there was a line */
printf("%s", longest);
return 0;
}
/* getline: read a line into s, return length */
int getline(char s[], int lim)
{
int c, i;
for (i=0; i<lim-1 && (c=getchar())!= EOF && c!='\n'; ++i)
s[i] = c;
if (c == '\n') {
s[i] = c;
++i;
}
s[i] = '\0';
return i;
}
/*copy: copy 'from' into 'to'; assume to is big enough */
void copy(char to[], char from[])
{
int i;
i = 0;
while ((to[i] = from[i]) != '\0')
++i;
}
