请教一点传参的知识。求大手子解答

[m0_38117705]

现有如下代码：
char* Get_File0_MD5(){ //获取1.sql的md5值
char capBuf[64] = {0};
static char tabBuf[64] = {0};
FILE *fp = NULL;
sprintf(capBuf,"%s","md5sum /mnt/hd1/ud.sql");
fp = popen(capBuf, "r");
while((fgets(tabBuf, sizeof(tabBuf), fp))!=NULL){
}
pclose(fp);
return tabBuf;
}

char* Get_File1_MD5(){ //获取1.sql的md5值
char capBuf[64] = {0};
static char tabBuf[64] = {0};
FILE *fp = NULL;
sprintf(capBuf,"%s","md5sum /mnt/hd1/1.sql");
fp = popen(capBuf, "r");
while((fgets(tabBuf, sizeof(tabBuf), fp))!=NULL){
}
pclose(fp);
return tabBuf;
}

char* Get_File2_MD5(){ //获取2.sql的md5值
char capBuf[64] = {0};
static char tabBuf[64] = {0};
FILE *fp = NULL;
sprintf(capBuf,"%s","md5sum /mnt/hd1/2.sql");
fp = popen(capBuf, "r");
while((fgets(tabBuf, sizeof(tabBuf), fp))!=NULL){
}
pclose(fp);
return tabBuf;
}

除了关键部分都是相同的，请教一下怎么设置参数然后写到里边使代码更简化。谢谢大家

引用 1 楼 ipqtjmqj 的回复:

char* Get_Filex_MD5(int x){ //获取1.sql的md5值
  char capBuf[64] = {0};
  static char tabBuf[64] = {0};
  FILE *fp = NULL;
  if (x == 0){
    sprintf(capBuf,"md5sum /mnt/hd1/ud.sql");
  } else{
    sprintf(capBuf, "md5sum /mnt/hd1/%d.sql", x);
  }
  fp = popen(capBuf, "r");
  while((fgets(tabBuf, sizeof(tabBuf), fp))!=NULL){
  }
  pclose(fp);
  return tabBuf;
}

真的谢谢您，调试了一下没有问题，也学到了。感激不尽
