I am trying to compile a small program on linux. Here is the code.
Code:
#include <stdio.h>
#define MAXLINE 1000
int getline(char line[], int maxline);
void copy(char to[], char from[]);
int main(){
int len;
int max;
char line[MAXLINE];
char longest[MAXLINE];
max = 0;
while((len = getline(line, MAXLINE)) > 0){
if(len > max) {
max = len;
copy(longest, line);
}
if(max > 0){
printf("%s", longest);
}
}
return 0;
}
int getline(char s[], int lim[]){
int c, i;
for(i = 0; i < lim-1 && (c = getchar()) != EOF && c != '\n'; ++i){
s[i] = c;
++i;
}
s[i] = '\0';
return i;
}
void copy(char to[], char from[]){
int i;
i = 0;
while((to[i] = from[i]) != '\0')
++i;
}
and here are the errors that gcc gave me.
line.c:5: error: conflicting types for ‘getline’
/usr/include/stdio.h:651: note: previous declaration of ‘getline’ was here
line.c:27: error: conflicting types for ‘getline’
/usr/include/stdio.h:651: note: previous declaration of ‘getline’ was here
line.c: In function ‘getline’:
line.c:30: warning: comparison between pointer and integer
I couldn't get error: conflicting types for getline fix.
