什么是c语言程序的真值表,真值表（C++）

对于 真值表都不陌生。其原理略

代码如下：

#include

#include

void TruthTable(const int n);

enum { FALSE, TRUE };

int main()

{

const int nBoolNum = 5;

TruthTable(nBoolNum);

return 0;

}

void TruthTable(const int N)

{

int nState = (int)pow(2.0, N);

int nTotalNum = nState * N;

int* nPtr = new int[nTotalNum];

int nRem, nDiv, nCol;

int nCount = 0; // N incerments

for (int nIndex = 0; nIndex < nState; ++nIndex)

{

nDiv = nIndex;

for (nCol = N - 1 + nCount; nCol >= 0 + nCount; --nCol)

{

nRem = nDiv % 2;

nDiv /= 2;

if (!nRem)

nPtr[nCol] = FALSE;

else

nPtr[nCol] = TRUE;

}

for (int i = nCount; i < N + nCount; ++i) // Display

std::cout << nPtr[i] << '\t';

nCount += N;

std::cout << std::endl;

}

delete[] nPtr;

}

运行结果：正确且每行生成的数值对应成功
