Print character in a for loop c++

Question

This is a pretty basic question as I am new to the C++ language but I have a program that takes a function to print a single character in a for loop. My code is shown below:

void printBar(const char symbol, int count){
    for (int i = 0;i <= count; i++){
        cout << symbol;
    }
}

and my main function is this:

int main(){
    int size = 8;
    const char* sym = "*":
    printBar(sym,size);

I want my result to look like this:

What am I doing wrong here?

Answer 1

You should say what goes wriong. Errors, wrong output.... But I can guess

First this loop is wrong

void printBar(const char symbol, int count){
    for (int i = 0;i <= count; i++){
        cout << symbol;
    }
}

it will print one too many char. You should have i < count

Second your function needs a char, but you pass in a char*

Do this

int main(){

int size = 8;
const char sym = '*':
printBar(sym,size);
