Find the error:
#include<stdio.h>
#include<stdlib.h>
int main()
{
unsigned char;
FILE *fp;
fp=fopen("trial", "r");
if(!fp)
{
printf("Unable to open file");
exit(1);
}
fclose(fp);
return 0;
}
IN C++, TRUE OR FALSE :
The statement delete p; deallocates the dynamic array that is pointed to by p.
In the statement cin >> y;, y can only be an int or double variable.
In an output statement, the newline character may be part of the string.
The extraction operator (>>) skips whitespace characters when searching for the next data in the input stream.

- Write a program that opens a specified text file then displays a list of all the unique words found in the file. Hint: Store each word as an element of a set. 5. Word Frequency Write a program that reads the contents of a text file. The program should create a dictio- nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word "the" appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value.
