Question

I’m having trouble with conversion. I cannot use strings in this program so I have to use char‘s – I get the error:

error C2664: 'printText' : cannot convert parameter 1 from 'const char [21]' to 'char'
1>          There is no context in which this conversion is possible

I’ve tried converting it to a const pointer:

void printText(const char* text[100] = "notextgiven"...

but it doesn’t seem to help, gives me more errors than anything.

My Program:

#include <iostream>
using namespace std;

void printText(char, char, int);

int main(){
    printText("I hear and I forget.", "*", 15);
}

void printText(char text[100] = "notextgiven", char symbol = ' ', int repeat = 10){
    int temp = 0;
    while(temp < repeat){
        cout << symbol;
            temp++;
    }

    cout << text;

    temp = 0;
    while(temp < repeat){
        cout << symbol << endl;
            temp++
    }
}

This is not the right way to define your function for what you are trying to do

void printText(char text[100] = "notextgiven", char symbol = ' ', int repeat = 10)

try this instead

void printText(const char* text, char symbol, int repeat)

this should allow your program to compile. Also change this line

 printText("I hear and I forget.", "*", 15);

to

printText("I hear and I forget.", '*', 15);
                                  ^ ^ 

single quotes are used for a single char variable, double quotes treat it as a string literal. As this is homework, you may have been asked to specifically use char* but since you are using C++ in general you would be much better off using std::string
