7.7 lab: warm up: drawing a right triangle this program will output a right triangle based on user specified height triangleheight and symbol trianglechar. (1) the given program outputs a fixed-height triangle using a * character. modify the given program to output a right triangle that instead uses the user-specified trianglechar character. (1 pt) (2) modify the program to use a nested loop to output a right triangle of height triangleheight. the first line will have one user-specified character, such as % or *. each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangleheight. output a space after each user-specified character, including after the line's last user-specified character. (2 pts) example output for trianglechar = % and triangleheight = 5:
