I have written the program using C PROGRAMMING LANGUAGE.

CODE :

/*Included the required libraries*/

#include <stdio.h>

#include <string.h>

#define MAX 256 // constant defined

//main method

int main() {

int num;

FILE *fp1, *fp2;

char ch, src[MAX], tgt[MAX];

/* input file name from the user */

printf("Enter your input file name: ");

scanf("%s", src);

/* output filename from the user */

printf("Enter your output file name: ");

scanf("%s", tgt);

//opened the source file in read mode

fp1 = fopen(src, "r");

if (!fp1) {

printf("Unable to open the input file!!\n");

return 0;

}

//opened the target file in read mode

fp2 = fopen(tgt, "wb");

if (!fp2) {

printf("Unable to open the output file!!\n");

return 0;

}

/* read data from input file and write

the binary form of it in output file*/

while (!feof(fp1)) {

/* reading one byte of data */

fread(&ch, sizeof(char), 1, fp1);

/* converting the character to ascii integer value */

num = ch;

/* writing 4 byte of data to the output file */

fwrite(&num, sizeof(int), 1, fp2);

}

/* close all opened files */

fclose(fp1);

fclose(fp2);

return 0;

}
