True or false? a binary file can never contain image or audio data.
Answer:
true
Explanation:
It is true that a binary file can never contain image or audio data.
What is a binary file?A binary file is one that contains data in binary format, which consists of a series of sequential bytes, each of which is eight bits long.
The content must be interpreted by a program or a hardware processor that knows exactly how the content is formatted and how to read the data in advance.
Binary files are more efficient, which is one of their benefits. In terms of memory, storing values in numeric formats like IEEE 754, rather than text characters, uses less memory.
Furthermore, binary formats provide advantages in terms of access speed. Image or audio data can never be stored in a binary file.
Thus, the given statement is true.

You will read in two strings from a file cp4in_1. Txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i]
Use the knowledge in computational language in C++ to write the a character array .
How to define an array in C++?An Array is a set of values arranged in lists and accessible through a positive numeric index. So, we have that each position of our Array is a variable of the type of our Array, so we have to have a way to initialize this set of variables.
So in an easier way we have that the code is:
#include <stdio.h>
#include <studlib.h>
int main()
{
File*fp;
fp=fopen("cp4in_1.txt","r");
char ch;
//while(1)
//{
while(!feof(fp))
{
char *s1,*s2,*s3;
s1 = (char*)malloc (20 *sizeof (char));
s2 = (char*)malloc (20 *sizeof (char));
s3 = (char*)malloc (20 *sizeof (char));
int i=0,j=0,x,y;
while(1)
{
ch=getc(fp);
if(ch=='\n')
break;
*(s1+i)=ch;
