Question

cannot convert parameter 1 from 'char'

#include <stdio.h>
#include <stdlib.h>
#define BUFSIZE 256
main()
{ char buff[BUFSIZE],file;
int c,lcnt;
FILE *fp;
puts("Input the file name:");
scanf("%s",file);
if((fp=fopen(file,"r"))==NULL)
{
printf("\7file %s can't opened\n",file);
exit(1);
}
lcnt=1;
while(fgets(buff,BUFSIZE,fp)!=NULL)
printf("%3d:%s",lcnt++,buff);
fclose(fp);
return 0;
}

小问题。定义数组file的时候格式不对。改成
char buff[BUFSIZE],file[10];就行了~
