redefinition of formal parameter 'temp'

补充：程序有几处错,你的32行
double temp[LENGTH] = {0};
这个是多余的定义(tmep已在参数中定义了)
另外
你程序中的\全写成/了
C/C++只有"\n",没有"/n"的
(如果网上抄的程序的话,会有很多错的)
如52行
printf("错误！找不到要读取的文件/"data.txt/"/n");
应该是
printf("错误！找不到要读取的文件\"data.txt\"\n");
(其它地方的/n也要改)
还有就是54行
fscanf(fp,"%d", &data[count]);
你的count没定义
(没研究你的程序,只是语法上看下)
追问：G:\Cpp1.cpp(52) : error C2146: syntax error : missing ')' before identifier 'data' 这个呢我实在找不到错在哪里
