Please help me find a solution for this question below.

Write a C++ function display prototyped by

int display(char ch, int n);

that displays the character ch on the stdout device (screen) consecutively n times if n>0 and displays nothings if n≤0. When n>0 and ch is not the blank character, the function will also display an additional newline at the end. The function display returns the actual number of characters (excluding the possible newline at the end) displayed.

Write a driver program, making use of the above specified function display, that line by line repeatedly displays the character pattern

until a given numer of non-whitespace characters are displayed. In other words, the program will first ask the user to enter the total number, say target, of non-whitespace characters to be displayed, and then it will repeatedly display the above pattern until exactly target non-whitespace characters are displayed. For instance, if target is entered as 150, then the program will produce the following output (containging exactly 150 non-whitespace characters) afterwards:

Many thanks in advance.

I was given some tips for this question, and the below is the tips.

#include<iostream>
using namespace std;

// display ch consecutively for n times
int display(char, int);

int main( )
{
// declare and initialise variables
// prompt and input the total number of non-whitespace characters

// loop the display of * pyramid and + pyramid
while ( ... ) // compare total with target?
{
// loop through the * shape
// find how many non-space characters to display in next line
// leave the loop if the target is met
// display the leading blanks in a line
// display * for the rest of the line
// update the total number of displayed characters

// loop through the + shape
// similar to the * case
}

system("pause");
return 0;
}


int display(char ch, int n)
{
// display the characters ch for n times
// display the trailing newline if needed
// return a proper value
}

see if you can follow along to see how i did some of the things. that will help you try to make your project.
