紧急问题：Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

[godaga]

本程序的目的是为了让此C程序 在VC里编译通过运行

对于b[][] vc编译一直提示出错。。。。。。。。。

请帮忙 谢谢





// temp.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

int convert(int b[]);

int main(int argc, char* argv[])
{
int a[3][6];

a[0][0] = 1;
a[0][1] = 2;
a[0][2] = 3;
a[1][0] = 4;
a[1][1] = 5;
a[1][2] = 6;
a[2][0] = 7;
a[2][1] = 8;
a[2][2] = 9;

convert( a );
return 0;
}

int convert(int b[])
{
int i,j;
int num;

for(i=0;i<3;i++)
for(j=0;j<3;j++)
{
num = b[i*3+j];
printf("hello %d\n",num);
}

return 1;
}


错误提示：:\My Documents\zej\temp\temp.cpp(22) : error C2664: 'convert' : cannot convert parameter 1 from 'int [3][6]' to 'int []'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

类型不匹配错误，使用C风格的
convert ((int *)a)
或者C++风格的
convert (reinterpret_cast <int *> (a))
的强制转型。

因为在主函数中是二维数组，而在convert(int b[])中的参数是一维数组，因此会出错其方法是把convert(int b[])改为convert(int *b)

[林雨亭]

convert( int b[]) --> convert ( int b[][6])
or
-->convert( int ** b)
num = b + 3 * i + j;

try it.
