myod

要求

编写myod.c 用myod XXX实现Linux下od -tx -tc XXX的功能

编写myod.c

    #include<stdio.h>
    #include<stdlib.h>
    void main()
    {
    
        char filename[50];
        void Hexa(char *filename);
        void ascii(char *filename);
        printf("input filename: ");
        scanf("%s",filename);
        ascii(filename);
        Hexa(filename);
    }

编写hex.c

    #include<stdio.h>
    #include<stdlib.h>
    void Hexa(char *filename)
    {
        FILE *fp;
        char ch;
        printf("Hexadecimal numbers: \n");
        fp=fopen(filename,"r");
        ch=fgetc(fp);
        while(ch != EOF)
        {
            if(ch=='\n')
            {
                printf("\n");
            }
            else
            {
                printf("%x, ",ch);
            }
            ch=fgetc(fp);
        }
        fclose(fp);
    }

编写ASCII.c

    #include<stdio.h>
    #include<stdlib.h>
    void ascii(char *filename)
    {
        FILE *fp;
        char ch;
        fp=fopen(filename,"r");
        ch=fgetc(fp);
        printf("ascii: \n");
        while(ch != EOF)
        {
            if(ch=='\n')
            {
                printf("\n");
            }
            else
            {
                printf("%d, ",ch);
            }
            ch=fgetc(fp);
        }
    }
