c - 我如何搜索 argv 是否以 char 结尾

Question

我如何检查 argv 是否以字符结尾？例如，如果我想查看 agv[1] 是否以字符 z 结尾，我该如何编写程序。

if(argv[1] == ? )
    printf("The input entered ends with the character z");

Answer 1

#include <stdio.h>
#include <string.h>

int main(int argc, char** argv)
{
  int string_length;

  if(argc < 2)
    printf("\n no arguments \n");
  else if(argc > 1)
    {
      string_length = strlen(argv[1]);
      if(argv[1][string_length - 1] == 'z')
        printf("\n The input entered ends with the character z \n");
      else
        printf("\n The input entered ends without the character z \n");
    }
}
