帮忙解释下错怎么改

程序代码：

#include <stdio.h>
#include<stdlib.h>
int N,Hn,Tn,s;
char L,H,T;
float Load[6][4],Gh[6][7],Gt[6][6];
main()
{
    FILE *fp;
    fp=fopen("jingjifenpeishuju.txt","r");
    if(fp==NULL)
    {
        printf("cannot find this file\n");
        exit(1);
    }
    int i,j;
    fscanf(fp,"%c%d",&L,&N);//读负荷数据
    for(s=1;s<N;s++)
    {
        for(j=1;j<4;j++)
        {
            fscanf(fp,"%f",&Load[s][j]);
        }
    }
    fscanf(fp,"%c",&H);//读水电厂数据
    while(H!='H')
    {
        fscanf(fp,"%c",&H);
    }
    fscanf(fp,"%d",&Hn);
    for(i=1;i<=Hn;i++)
    {
        for(j=1;j<7;j++)
        {
            fscanf(fp,"%f",&Gh[i][j]);
        }
    }
    fscanf(fp,"%c",&T);//读火电厂数据
    while(T!='T')
    {
        fscanf(fp,"%c",&T);
    }
    fscanf(fp,"%d",&Tn);
    for(i=1;i<=Tn;i++)
    {
        for(j=1;j<6;j++)
        {
            fscanf(fp,"%f",&Gt[i][j]);
        }
    }
    fclose(fp);
    printf("%d\n%d\n%d\n",N,Hn,Tn);
}
