Answer in C please. Write a recursive function void recur Triangle (int n, char ch) which prints out upright triangle. The parameter ch is the character to be used for drawing the triangle, and n is the number of characters on the first row. For example, if n is 5 and ch is \'#\', then the output of the function should be: Solution #include <stdio.h> void uprightTriangle(int n,char ch) { if (n==1) { printf(\"%c\ \",ch); } else { uprightTriangle(n-1,ch); for (int i=0; i<n; i++) { printf(\"%c\",ch); } printf(\"\ \"); } } int main() { uprightTriangle(5,\'#\'); return 0; } .
