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
