Write a new program indent. cpp that enhances the program from the previous task. As it reads the input line by line, it should also count the number of open and closed { } in it, and keep track of how many blocks is currently open at the beginning of each line.

Explanation:

#include <iostream>

#include <conio.h>

#include <string>

using namespace std;

//Define the function to count a

// specific character in a line.

int countChar(string line, char c)

{

//Define the variable.

int tc = 0;

//Iterate through the string.

for (int i = 0; i < line.length(); i++)

{

//Find the matching character.

if (line[i] == c)

tc++;

}

//Return the character counts.

return tc;

}

//Define the function to remove the spaces.

string removeSpace(string input)

{

//Find the string length.

int strlength = input.length();

//Itearte through the string.

for (int i = 0; i < strlength; i++) {

//set the value.

i = 0;

//Check for the spaces.

if (input[i] == ' ') {

//Remove the extra space.

for (int j = 0; j < strlength; j++) {

input[j] = input[j + 1];

}

//Update the string length.

strlength--;

}

//if there is no extra space left.

else

break;

}

//Return the input string

return input;

}

//Define the main function.

int main() {

//Define the variables.

int n, ind = 0, ob = 0;

string lines[100], input;

int max = 0;

//Prompt the user for input.

cout << "Enter lines one by one: " << endl;

//Get the user input and exit when

// user enters twice after the input.

do

{

getline(cin, input);

//Remove the extra space.

input = removeSpace(input);

//Store the line by line input in the

//String array.

if (input.length() > max)

max = input.length();

lines[ind++].append(input);

} while (!input.empty() != 0);

//Set the value for number of lines.

n = ind;

cout << endl;

//Dsipaly the message

cout << endl << "Indented code is:" << endl << endl;

//Iterate through the string array.

for (int i = 0; i <= n; i++)

{

string tab = "";

//Check for the closing braces.

int close = countChar(lines[i], '}');

//Set the value for braces.

ob -= close;

//Indent the code.

for (int j = 0; j < ob; j++)

{

tab += " ";//it takes 4 whitespace

//tab+= "\t";//it takes 8 whitespace

}

//Print the line.

cout << tab << lines[i]<< endl;

//Check for the opening braces.

int op = countChar(lines[i], '{');

//Update the opening brace count.

ob = ob + op;

}

//system("pause");

//Return the value 0.

return 0;
