I need help with this problem for computer science, have had difficulties figuring out for loops, please help, sorry the pyramid is kinda messed up but it's supposed to be a pyramid

Prog3d: Use for loops to construct a program that displays a pyramid of $ on the screen. The pyramid should look like this: [4] $ $$$ $$$$$ $$$$$$$ $$$$$$$$$ Note: There is no space in front of the first $ of last row. The above example shows only 5 lines however your program should take any integer input from the user corresponding to the number of rows to be shown. You must use the following methods:

int main()

int getNumberOfRowsFromUser()

void drawPyramid(int)
