error C2143: 语法错误 : 缺少“;”(在“类型”的前面)

C编程老是遇到这个问题：

错误        error C2143: 语法错误 : 缺少“;”(在“类型”的前面)    d:\kinectproject\ceshiglad\ceshiglad\shili.c            ceshiGLAD

#include <stdio.h>

double Alpha[]={,,,,};
double Beta[]={,,,,,,,,,};
double Z1[]={,,,,,,,,,};
double labels[]={,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,};

void main(){

    int i,j;
    double *rawPriorBeta = Beta;
    double *rawPriorZ1 = Z1;
    double *rawLabels = labels;
    double *rawPriorAlpha = Alpha;
    Dataset data;
    data.numLabels = ;
    data.numLabelers = ;
    data.numImages = ;
    data.priorZ1 = (double *) malloc(sizeof(double) * data.numImages);
    data.priorAlpha = (double *) malloc(sizeof(double) * data.numLabelers);
    data.priorBeta = (double *) malloc(sizeof(double) * data.numImages);

    for (i = ; i < data.numLabelers; i++) {
        data.priorAlpha[i] = rawPriorAlpha[i];
    }

    for (j = ; j < data.numImages; j++) {
        data.priorBeta[j] = rawPriorBeta[j];
        data.priorZ1[j] = rawPriorZ1[j];
    }

    data.probZ1 = (double *) malloc(sizeof(double) * data.numImages);
    data.probZ0 = (double *) malloc(sizeof(double) * data.numImages);
    data.beta = (double *) malloc(sizeof(double) * data.numImages);
    data.alpha = (double *) malloc(sizeof(double) * data.numLabelers);
    data.labels = (Label *) malloc(sizeof(Label) * data.numLabels);

    for (i = ; i < data.numLabels; i++) {
        /* Remember that Matlab stores data in row-major order! */
        data.labels[i].imageIdx = rawLabels[i];
        data.labels[i].labelerId = rawLabels[data.numLabels + i];
        data.labels[i].label = rawLabels[ * data.numLabels + i];
    }
}

后来发现，把变量的声明放到main函数的前面，就不会有这个问题了，虽然不知道为什么，但是记一下。
