[c++] How to replace all occurrences of a character in string?

This works! I used something similar to this for a bookstore app, where the inventory was stored in a CSV (like a .dat file). But in the case of a single char, meaning the replacer is only a single char, e.g.'|', it must be in double quotes "|" in order not to throw an invalid conversion const char.

#include <iostream>
#include <string>

using namespace std;

int main()
{
    int count = 0;  // for the number of occurences.
    // final hold variable of corrected word up to the npos=j
    string holdWord = "";
    // a temp var in order to replace 0 to new npos
    string holdTemp = "";
    // a csv for a an entry in a book store
    string holdLetter = "Big Java 7th Ed,Horstman,978-1118431115,99.85";

    // j = npos
    for (int j = 0; j < holdLetter.length(); j++) {

        if (holdLetter[j] == ',') {

            if ( count == 0 ) 
            {           
                holdWord = holdLetter.replace(j, 1, " | ");      
            }
            else {

                string holdTemp1 = holdLetter.replace(j, 1, " | ");

                // since replacement is three positions in length,
                // must replace new replacement's 0 to npos-3, with
                // the 0 to npos - 3 of the old replacement 
                holdTemp = holdTemp1.replace(0, j-3, holdWord, 0, j-3); 

                holdWord = "";

                holdWord = holdTemp;

            }
            holdTemp = "";
            count++;
        }
    } 
    cout << holdWord << endl;
    return 0;
}

// result:
Big Java 7th Ed | Horstman | 978-1118431115 | 99.85
