C语言-字符数组

示例

#include <stdio.h>
#include <string.h>
int main(){
  // 字符数组的初始化
  char str1[] = "abcdefgh";
  char str2[] = {'a','b','c','d','e','f','g','h'};
  // char str3[] = {"a","b","c","d"}; // 错误的，是单引号
  char str4[100] = {0};


  // 求字符串的长度
  int length_str1 = strlen(str1);
  printf("length_str1 = %d\n",length_str1);

  //求数组内元素个数
  int length_str2 = sizeof(str2) / sizeof(str2[0]);
  printf("length_str2 = %d\n",length_str2);
  return 0;
}
