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;
}
