Write a program that reads a text file and creates another file that is identical except that every sequence of consecutive blank spaces is replaced by a single space.
To solve this problem, we can follow these steps: Open the input file for reading and the output file for writing. Read the input file line by line. For each line, replace every sequence of consecutive blank spaces with a single space using the std::regex_replace function from the regex library. Write the modified line to the output file. Here is the code: #include <iostream> #include <fstream> #include <regex> using namespace std; int main() { // Open the input file for reading and the output file for writing ifstream infile("input.txt"); ofstream outfile("output.txt"); if (!infile) { cerr << "Error: Could not open input file.\n"; return 1; } if (!outfile) { cerr << "Error: Could not open output file.\n"; return 1; } string lin...
