C編譯時cmath錯誤

我一直堅持這個很長一段時間，由於某種原因，我的C代碼不編譯。它產生了大量CMATH錯誤C編譯時cmath錯誤

，因爲它會採取了很多的空間來把我的代碼和錯誤起來：

#include <stdlib.h> 
#include <stdio.h> 
#include <Windows.h> 
#include <fstream> 

typedef unsigned char* pointer; 

void printDbPointers(void); 
void show_int(int); 
void show_bytes(unsigned char*, int); 
void floatingPointRep(); 
void fahrenheit(); 

int main() 
{ 
    int a = 100; 
    show_int(a); 
    floatingPointRep(); 
    fahrenheit(); 
    printDbPointers(); 
    Sleep(100000); 
    return 0; 
} 

void printDbPointers(){ 
    char hi[7] = {'t', 'i', 'g', 'e', 'r', '\0'}; 
    char *p, **dp; 

    p = &(hi[0]); 
    dp = &p; 

    printf("%c %c\n", *p, **dp); 
    printf("%p %p %p\n", p, *dp, hi); 
    p+=1; 
    printf("%c, %c\n", *p, **dp); 
    printf("%p %p %p\n", p, *dp, hi); 
    *dp+=2; 
    printf("%c, %c\n", *p, **dp); 
    printf("%p %p %p\n", p, *dp, hi); 
} 


void show_int(int x) 
{ 
    show_bytes((pointer) &x, sizeof(int)); 
} 

void show_bytes(pointer start, int len) 
{ 
    int i; 
    for(i=0;i<len;i++) 
    { 
     // printf("0x%p\t0x%.2x\n", start + i, start[i]); 
     printf("0x%p\t\n", start + i, start[i]); 
     printf("\n"); 
    } 
} 


void floatingPointRep() 
{ 
    float f1 = 1.0; 
    float f2 = 0.0; 
    int i; 
    for (i=0; i<10; i++) { 
     f2 += 1.0/10.0; 
    } 

    printf("0x%08x 0x%08x\n", *(int*)&f1, *(int*)&f2); 
    printf("f1 = %10.8f\n", f1); 
    printf("f2 = %10.8f\n\n", f2); 

    f1 = 1E30; 
    f2 = 1E-30; 
} 

void fahrenheit() 
{ 
    int i; 
    double arr[3] = {12345678.000, 98765345.333, 456793332.300}; 
    for (i = 0; i < 3; i++) 
    printf ("%g\n", arr[i]); 
}

但是，如果它違反了這樣的規則把問題代碼別的地方，讓我知道，我會把它放在這裏

你有#included math.h嗎？ – 2012-07-06 18:28:59

根本不是。這是這裏的奧祕。看到我上面的代碼鏈接。 – jmishra 2012-07-06 18:29:24

似乎有些混亂。你有#include fstream，但這是C++的一部分，不是C. – 2012-07-06 18:31:10

似乎有一些混淆。你有#included fstream，這是C++的一部分，而不是C.

似乎fstream由於某種原因自己做了#include cmath，而這些錯誤可能來自C和C++之間的不兼容。

編輯：

是，之後＃包括幾個層次，CMATH被執行#included，並且CMATH不僅僅是math.h中的副本，但包含了C++ - 特定代碼。
