错误1错误LNK2019：函数___tmainCRTStartup中引用了未解析的外部符号_main

Question

#include "tbb/parallel_for.h"
#include "tbb/blocked_range.h"

using namespace tbb;

struct Average
{
float* input;
float* output;

void operator()( const blocked_range<int>& range ) const 
{
 for( int i=range.begin(); i!=range.end(); ++i )
 output[i] = (input[i-1]+input[i]+input[i+1])*(1/3.0f);
 }
 };

 void ParallelAverage( float* output, float* input, size_t n ) 
 {
 Average avg;
 avg.input = input;
 avg.output = output;
 parallel_for( blocked_range<int>( 0, n, 1000 ), avg );
}

这是我的c ++代码

当我运行此代码时，我收到错误声明，如下所示
