//base width b

The only library functions you are allowed to use are: cmath, climits, cstdlib: all String: empty, length, conatenation, indexing/at, relational operators iostream: , >>, getline (with cin, cout, cerr) fsream: all of above, open, close, eof, fail (22%) Write a code fragment to output a trapezoid with basa width b, and height h. For example, with b=10, and h=4, the following would be output: 123 *48 Your code should also input b and h and output an error message to cerr if they are not legal (but you may assume,an infinitel y wids/high window).
