if consider this: int *var1; const int *var2 = var1; why *var1 = x; compile , *var2 = x; does not? in case *var2 = x; fails compile error message ( approx ), error: assignment of read-only location *var2 *var2 = 10; ^ because have marked value of const qualified. to elaborate, can read statement like const int *var2; as, declare var2 pointer const int . value pointed var2 constant , cannot changed. in case want pointer const-qualified, need write like int * const var2; which declaring var2 const pointer int . so, later attempt assign var2 produce error, accessing *var2 work fine, value pointed pointer not const-qualified anymore.

(gdb) whatis myintvalue int (gdb) set $typeint = whatis myintvalue // it's impossible want (gdb) p *($typeint)0xabcd // address having int value i want use above casting generic memory address template class type (which has very long name). and casting type variant hard put every single name while debugging. there's no way assign type convenience variable. however, can saving value in convenience variable , using typeof : (gdb) set $x = 23ll (gdb) ptype $x type = long long (gdb) ptype (typeof($x))'z' type = long long

i little confused @ different distribution functions out there (i.e. numpy, scipy, matploglib.mlab, , random) i trying sampling of gamma distribution numbers use program , plot out distribution being used well. so far doing: import random import matplotlib.pyplot plt import matplotlib.mlab mlab import scipy.special sps import numpy np k = 2.0 theta = 2.0 random.gammavariate(k, theta) # gives me results of gamma distribution # unfortunately, doesn't work # plt.plot(random.gammavariate(k, theta)) # plt.show() # works somehow if don't specify # bins , y - copied https://docs.scipy.org/doc/numpy/reference/generated/numpy.random.gamma.html # , seems work s = np.random.gamma(k, theta, 1000) plt.plot(bins, y, linewidth=2, color='r') any explaining me appreciated. you trying plot curve (or scatter) of 1 dimensional data. can show distribution plotting histogram: plt.hist(np.random.gamma(k, theta,100 )) note 1000 give 1000 points. if want extract inf...
