尽管在main()之前声明了"getline“和"copy”函数原型,但我还是收到了这些错误。这个程序直接来自C编程语言的代码,所以我不确定问题是什么以及如何修复它。
#include <stdio.h>
int getline(char line[], int maxline);
void copy(char to[], char from[]);
int main()
{
}
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;
}
void copy(char to[], char from[])
{
int i;
i = 0;
while ((to[i] = from[i]) != '\0')
++i;
}
编译器产生的确切错误是:
string_reverser.c:4:5: error: conflicting types for 'getline'
int getline(char line[], int maxline);
