Question

Write a program to translate the English alphabet to binary strings according to the above correspondence and store the result in a file. So ‘c’represented as 00010, ‘d’represented as 00011. So if your input is cd, The output in the file will be 0001000011. Also, read the binary strings from the file and translate it to Alphabet. Use 5 bits to represent your binary data Verify your result that you get the same alphabet from a binary string. It's a C program.

Sample storing file: store.txt

Sample Output:

Code to Copy:

// declare a necessary header files.

#include <stdio.h>

#include<string.h>

#include<stdlib.h>

#include <math.h>

// start the main function.

int main(void) {

// declare arrays

char arr[50];

char arr1[50];

int i=0;

// declare file pointer and open the file.

FILE *fptr;

fptr = fopen("store.txt","w");

// prompt the user to enter th eword.

printf("Enter a word:\n");

scanf("%s",arr);

// start the for loop.

for(i=0;i<strlen(arr);i++)

{

int n = (int)(arr[i]-97);

int j=0;

// START THE WHILE LOOP

while(n>0)

{

// get the binary equivalent of a number.

int r=n%2;

arr1[j]=r;

n=n/2;

j++;

}

char arr2[5]={0,0,0,0,0};

int k = 4;

int p = 0;

// start the loop.

while (p<j)

{

arr2[k] = arr1[p];

p++;

k--;

}

int l = 0;

// start the for loop

for( l=0;l<5;l++)

{

// store the value in a file.

fprintf(fptr, "%d", arr2[l]);

}

}

fclose(fptr);

char num;

// open the file in read mode.

if ((fptr = fopen("store.txt","r")) == NULL){

printf("Error! opening file");

exit(1);

}

int n=strlen(arr);

int k = 0;

printf("Alphabets after reading the binary strings from the file:");

// start the while loop

while(k<n)

{

int x =0;

char bin_arr[5];

// start the whiel loop.

while(x<5)

{

fscanf(fptr,"%c", &num);

bin_arr[x] = num;

x++;

}

int y = 0;

int num_val = 0;

// start the for loop.

for(y=0;y<5;y++)

{

// check the condition.

if(bin_arr[y] == '1')

{

num_val = num_val + pow(2,4-y);

}

}

char req_char = num_val + 97;

// display the result on console

printf("%c", req_char);

k++;

}

fclose(fptr);

return 0;
