第二周选答题-myod

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);
}
}

编译并运行
