表情符那里是个右括号，下面&data后面有&data【i】

long i=0, ndata;
float tempdata;

FILE *fp;
fp=fopen("filename.txt","r");
while (feof(fp)==0){
   fscanf(fp,"%f",&tempdata);
   i++;
}
ndata=i;
rewind(fp);
float data[ndata];

while (feof(fp)==0){
   fscanf(fp,"%f",&data[i]);
   i++;
}
fclose(fp);

long i=0, ndata;
float tempdata;

FILE *fp;
fp=fopen("filename.txt","r");
while (feof(fp)==0){
   fscanf(fp,"%f",&tempdata);
   i++;
}
ndata=i;
rewind(fp);
float data[ndata];

while (feof(fp)==0){
   fscanf(fp,"%f",&data[i]);
   i++;
}
fclose(fp);
