问题描述

谁能告诉我如何比较char数组的值?

我的代码示例:

Hi,

Can anyone tell me that how can I compare a value of char array?

My code sample:

typedef struct
{
  char pDocId[14 + 1];
} sBlocRepSRR;

typedef struct
{
  sBlocRepSRR pBlocRepSRR[MAX_REPONSES + 1];
}sRepSRR;

void func(sRepSRR * pResponse)
{
 for (i=0; i<icount; i++)
 {
   if (pResponse->pBlocRepSRR[k].pDocId_PDF < pResponse->pBlocRepSRR[j].pDocId_PDF)
   {    
        printf("k is less than j\n");
        k = j;        
   } else {   
        printf("k is greater than j\n");
        k = k;       
   }
 }
 printf("Maximum value is %s\n", pResponse->pBlocRepSRR[k].pDocId_PDF);
}

其中pResponse-> pBlocRepSRR [k] .pDocId_PDF的值为"020000001110"/"025000000556"/"02500000204"等...

请帮我从字符数组中获取最大价值.
在此先感谢.

where values of pResponse->pBlocRepSRR[k].pDocId_PDF are "020000001110" / "025000000556" / "02500000204" etc...

Please help me out for getting maximum value from character array.
Thanks in advance.

推荐答案

int strcmp(const char *string1, const char *string2);

返回的值可能是:

The returned value could be:

<如果string1小于string2

< 0 if string1 is less than string2

= 0 如果string1等于string2

= 0 if string1 is equal to string2

>如果string1大于string2

if (pResponse->pBlocRepSRR[k].pDocId_PDF < pResponse->pBlocRepSRR[j].pDocId_PDF)

更改为:

Change to:

long lk, lj;
lk = atol(pResponse->pBlocRepSRR[k].pDocId_PDF);
lj = atol(pResponse->pBlocRepSRR[j].pDocId_PDF);
if ( lk < lj )
