为什么写不入文件？

breezeforever

int MyFile;
        int LoanNumber,i;
        // Assigning the file path to a string
        char FileName[80] = "E:\\TestProj\\Award\\test.txt";


        // Opening the file
        // Note the use of variable to replace the file path
        //

        MyFile = (int)fopen(FileName,"w");
       
       
        // Reading and printing one loan number at a time
        for(i=1;i<=5;i++)
                {
                    fscanf(MyFile,"%d", &LoanNumber);
                    lr_output_message("Loan Number %d: %d",i,LoanNumber);
                }

        fclose(MyFile);

        return 0;

Long MyFile;
int LoanNumber,i; //不知道LoanNumber是从什么地方获取的，也许有其他的脚本，到打印的时候也没有赋值
char *FileName = "E:\\TestProj\\Award\\test.txt";
MyFile = fopen(FileName,"a+");
for(i=1;i<=5;i++)
{
     fprintf(MyFile,"%d", &LoanNumber);
     lr_output_message("Loan Number %d: %d",i,LoanNumber);
}
fclose(MyFile);

//这样应该就没问题了吧

你用错函数了
Long MyFile;
int LoanNumber,i; //不知道LoanNumber是从什么地方获取的，也许有其他的脚本，到打印的时候也没有赋值
char *FileName = "E:\\TestProj\\Award\\test.txt";
MyFile = fopen(FileName,"a+");\\The type fo access mode: r, w, a or r+, w+, a+, where the "+" sign
// indicates that the file must already exist.
for(i=1;i<=5;i++)
{
   fprintf(MyFile,"%d", LoanNumber);  
   lr_output_message("Loan Number %d: %d",i,LoanNumber);
}
fclose(MyFile);


他要那个变量的地址没有用吧 我想他是想把写入的数据在通过lr_output_message显示出来  个人建议
