C连接int

Question

我将是第一个承认,我是100%的C#家伙而C不适合我.但是我有问题.我需要连接7与HashUrl(HashInt),然后与HashInt连接任何帮助将不胜感激.

int main(int argc)
{
unsigned int HashInt;
HashInt = HashURL(argc);
// I need to return 7 + CheckHash(HashInt) + HashInt but not ADDING, but concanenating them
return HOWEVERTOGETTHESTRING;
}

我应该已经指定了这个用法.它实际上将用于学生VB6项目.

Private Declare Function main Lib "checksum.dll" (ByVal pStr As String) As Long

Private Sub Command1_Click()
MsgBox main("http://hello.com")
End Sub

C库的完整源代码是

#include <stdio.h>
#include <string.h>
#include <windows.h>
#include <string.h>
#include <winreg.h>
#include <stdlib.h>

int StrToInt(char *pStr, int Init, int Factor)
{
while (*pStr) {
Init *= Factor; 
Init += *pStr++;
}
return Init;
}

int HashURL(char *pStr)
{
unsigned int C1, C2, T1, T2;

C1 = StrToInt(pStr, 0x1505, 0x21);
C2 = StrToInt(pStr, 0, 0x1003F);
C1 >>= 2;
C1 = ((C1 >> 4) & 0x3FFFFC0) | (C1 & 0x3F);
C1 = ((C1 >> 4) & 0x3FFC00) | (C1 & 0x3FF);
C1 = ((C1 >> 4) & 0x3C000) | (C1 & 0x3FFF);

T1 = (C1 & 0x3C0) << 4;
T1 |= C1 & 0x3C;
T1 = (T1 << 2) | (C2 & 0xF0F);

T2 = (C1 & 0xFFFFC000) << 4;
T2 |= C1 & 0x3C00;
T2 = (T2 << 0xA) | (C2 & 0xF0F0000);

return (T1 | T2);
}

char CheckHash(unsigned int HashInt)
{
int Check = 0, Flag = 0;
int Remainder;

do {
Remainder = HashInt % 10;
HashInt /= 10;
if (1 == (Flag % 2) ){
Remainder += Remainder;
Remainder = (Remainder / 10) + (Remainder % 10);
}
Check += Remainder;
Flag ++;
} while( 0 != HashInt);

Check %= 10;
if (0 != Check) {
Check = 10 - Check;
if (1 == (Flag % 2)) {
if (1 == (Check % 2)) {
Check += 9;
}
Check >>= 1;
}
}
Check += 0x30;
return Check;
}

int main(int argc)
{
 unsigned int HashInt;
    int result;
    HashInt = HashURL(argc);
    char temp[100];
    sprintf(temp, "7%i%j", CheckHash(HashInt), HashInt);
    result = atoi(temp);
    return result;
}

Answer 1

您可以使用sprintf函数创建格式化字符串.要将3个整数连接成一个字符串,你可以使用类似的东西

sprintf(string, "%d%d%d", int1, int2, int3)

Answer 2

对于初学者，您可以查看：

asprintf

man asprintf只需在linux系统上进行即可。

这是一个包含一个简单示例的链接，您可以对其进行调整：
