帮我看看这段代码有什么问题？总是提示float b[5];出错
main()
{
long a;
printf( "please input your money (> 1000, and multiple): ");
scanf( "%ld ",&a) ;
while(a%1000)
{
printf( "%ld is not multiple of 1000\n ",a);
printf( "please input your money (> 1000, and multiple): ");
scanf( "%ld ",&a) ;
}
printf( "Please input everyday net value in this week:\n ");
float b[5];
int i;
for(i=0;i <5;i++)
{
scanf( "%f ",&b[i]);
}
printf( "Quotient Net Value Increase Rate Current Value Current Payoff\n ");
for(i=0;i <5;i++)
{
float c=a*(1-0.015)/1;
float d = 1.0f;
if(i> 0)
{
d=b[i-1];
}
float e;
e=b[i] ;
float f=e/d-1;
float g=c*e;
float h=f*(1-0.005)-a;
printf( "%f %f %f %f %f \n ",c,e,f,g,h);


}
}

[解决办法]
你是C还是C++
C的话变量要在函数的最开始定义

如果是C＋＋没有问题
