So she was considering in her own mind (as well as she could, for the2. hot day made her feel very sleepy and stupid), whether the pleasure3. of making a daisy-chain would be worth the trouble of getting up and#### a4.txt1. of making a daisy-chain would be worth the trouble of getting up and2. picking the daisies, when suddenly a White Rabbit with pink eyes ran3. close by her.#### a5.txt1. There was nothing so VERY remarkable in that; nor did Alice think it so2. VERY much out of the way to hear the Rabbit say to itself, 'Oh dear!3. Oh dear! I shall be late!' (when she thought it over afterwards, it#### a6.txt1. 'Well!' thought Alice to herself, 'after such a fall as this, I shall2. think nothing of tumbling down stairs! How brave they'll all think me at3. home! Why, I wouldn't say anything about it, even if I fell off the top4. of the house!' (Which was very likely true.) In the last two exercises, you counted words and lines. The `wc` program counts both, as well as the number of characters in the file. To count the characters and lines, you'll need to use line-oriented input and then use the line size (+1) for the character count. For the words, you'll need to use a string stream to count the words in each line.```$ wc a.txt b.txt c.txta.txt 5 32 182 # lines, words, charactersb.txt 10 151 587c.txt does not exist```### `wc.cpp`A C++ source file with the following includes:```cpp#include #include #include using namespace std;int main(int argc, char* argv[]){ }```### `a1.txt`Contains the following text:```1 Alice was beginning to get very tired of sitting by her sister on the2 bank, and of having nothing to do: once or twice she had peeped into the3 book her sister was reading, but it had no pictures or conversations in```### `a2.txt`Contains the following text:```1 OUT OF ITS WAISTCOAT-POCKET, and looked at it, and then hurried on,2 Alice started to her feet, for it flashed across her mind that she had3 never before seen a rabbit with either a waistcoat-pocket, or a watch4 to take out of it, and burning with curiosity, she ran across the field```

The algorithm for the program is as follows: 1. Input the number of .txt files and the all.txt files using command line arguments (Note:argc contains the number of arguments. argv[1] contains the name of the first file ,argv[2] the name of the second file,argv[3] the name of the third and so on.. fp is a file pointer that stores the current file ) 2. Iterate n times( n=number of .txt files ) 2a) count the number of characters and store in numc 2b) count the number of words and store in numw 2c) count the number of lines and store in numl 2d) output the number of lines,characters and words along with file name 2e) close the file pointed by the file pointer 3. perform 2 until all files have been processed Please find the complete program/source code in step 2. I have tested it and it's working :)#include <iostream> #include <fstream> #include <sstream> using namespace std; int main(int argc,char* argv[]) { int i; FILE *fp; int numc=0,numw=0,numl=0; char ch; for ( i = 1; i < argc; i++ ) { fp = fopen(argv[i], "r"); if(fp==NULL) { cout<< argv[i]<<" Does not exist "<<std::endl; } else { ch=fgetc(fp); while(ch!=EOF) { if(ch!=' ' && ch!='\n') numc++; if(ch==' ') numw++; if(ch=='\n') { numl++; numw++; } ch=fgetc(fp); } cout<< argv[i]<<" "+std::to_string(numl)+" "+std::to_string(numw)+" "+ std::to_string(numc)<<std::endl; } fclose(fp); } }
