Explanation / Answer

#include <fstream> #include <iostream> #include <string> using namespace std; void change5(string &essay) //changes all 5 to s { int loc; loc = essay.find_first_of("5"); //gets the position of the first 5 while(loc != -1) { essay[loc] = 's'; //replaces 5 with s loc = essay.find_first_of("5", loc + 1); //starts off finding the next 5 after what we just found } //keep searching until all clear } void capitalize(string &essay) //finds a . then capitalize's the letter 2 over { int loc; loc = essay.rfind(".", essay.size() - 2); //gets the position of the second to the last . essay[0] = toupper(essay[0]); //capitalize the first letter of the essay while(loc != -1) { essay[loc + 2] = toupper(essay[loc + 2]); //capitalize the letter loc = essay.rfind(".", loc - 1); //starts off finding the next . after what we just found } //keep searching until all clear } int main() { string filename; cout << "What's the essay name? "; //should be essay.txt getline(cin, filename); //gets the file name // filename = "essay.txt"; //while testing too lazy to input everytime comment out later ifstream inFile; inFile.open(filename.c_str()); //opens the given file for input if (!inFile) //if you can't open it { cout << "I could not open the file. Fooey. "; return 0; } string essay; getline(inFile, essay, ''); //reads the whole file into essay inFile.close(); //close file change5(essay); //we do change5's first so we just have to change all 5 to s and not have to worry about if it's first in the sentence capitalize(essay); cout << "Enter the output file name: "; getline(cin, filename); //gets the file name // filename = "correct.txt"; //while testing too lazy to input everytime comment out later ofstream outFile; outFile.open(filename.c_str()); //opens the given file for output outFile << essay; outFile.close(); system("pause"); return 0; }
