strchr()函数

  原型:extern char *strchr(const char *s,char c);
  头文件:#include <string.h>
  功能:查找字符串s中首次出现字符c的位置
  说明:返回首次出现c的位置的指针,如果s中不存在c则返回NULL。
  举例1:(在Visual C++ 6.0中运行通过)
  #include <string.h>
  #include <stdio.h>
  int main(void)
  {
  char string[15];
  char *ptr, c = 'r';
  strcpy(string, "This is a string");
  ptr = strchr(string, c);
  if (ptr)
  printf("The character %c is at position: %d\n", c, ptr-string);
  else
  printf("The character was not found\n");
  return 0;
  }
  运行结果:The character r is at position: 12Press any key to continue
  举例2:
  // strchr.c
  #include <stdio.h>
  #include <string.h>
  main()
  {
  char temp[32];
  memset(temp,0,sizeof(temp));
  strcpy(temp,"Golden Global View");
  char *s = temp;
  char *p,c='v';
  p=strchr(s,c);
  if(p)
  printf("%s",p);
  else
  printf("Not Found!");
  return 0;
  }
  运行结果:Not Found!Press any key to continue
