Question

Please help run all the examples correctly and only the examples without extra things in or less things in, it should run EXACTLY 100% like the examples. C language ONLY. And please dont reply if you cant run all the examples given.

We know the tr command allows you to replace or translate characters in of a stream. It takes in two arguments - a set of characters to be replaced and a set of replacement characters. The full functionality of the command can be found using man tr, but this problem only requires a basic implementation capable of solving the examples below.

Write a program that implements basic tr functionality. Your program should take two arguments - the set of characters to be replaced and a set of replacement characters. It should then read one line of input from the standard in and translate it as shown in examples below.

Example 1

$ ./tr abc def

Input

abc aabbcc aaabbbccc

Output

def ddeeff dddeeefff

Example 2

$ ./tr xy XY

Input

xxyyxx
Lorem ipsum dolor sit amet
xxyyxx

Output

XXYYXX
Lorem ipsum dolor sit amet
XXYYXX

Example 3

$ ./tr ab xyz

Output

Invalid arguments

Example 4

$ ./tr

Output

No arguments

Example 5

$ ./tr abc

Output

Not enough arguments

Example 6

$ ./tr abc def ghi

Output

Too many arguments

a tutor did this below code but it doesnt even run properly and he has put information that are not even part of the examples given :

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_CHARS 100

int main(int argc, char* argv[]) {
//printf("no. of arguments: %d\n",argc);
char* characters_to_be_replaced=argv[1]; //characters to be replaced
char* replacement_characters=argv[2]; //replacement characters
//int num_characters_to_be_replaced=strlen(characters_to_be_replaced);
//int num_replacement_characters=strlen(replacement_characters);
//printf("characters to be replaced:%s, length:%d\n",characters_to_be_replaced,strlen(characters_to_be_replaced));
//printf("replacement characters:%s\n",replacement_characters);
char input[MAX_CHARS],input_char, replacement_char,output[MAX_CHARS];
int input_length=0,i;
printf("Input:\n");
fflush(stdout);
fgets(input, MAX_CHARS, stdin);
input_length=strlen(input);
//printf("input:%s,length:%d\n",input,input_length);
int found_at;
//printf("Processing input...\n");
for(i=0;i<input_length;i++)
{
input_char=input[i];
//printf("c:%c\n",input_char);
if(input_char!=' ')
{
char* ptr=strchr(characters_to_be_replaced,input_char);
if(ptr!=NULL)
{
//printf("found at:%d\n",ptr-characters_to_be_replaced);
found_at=ptr-characters_to_be_replaced;
//printf("read:%c,replacement:%c\n",input_char,*(replacement_characters+found_at));
replacement_char=*(replacement_characters+found_at);
}
output[i]=replacement_char;
}
else
{
//printf("input char:%c\n",input_char);
output[i]=input_char;
}
}
printf("Output:");
for(i=0;i<input_length;i++)
{
printf("%c",output[i]);
}
return EXIT_SUCCESS;
}
