you've gotten punctuation wrong in more 1 of onclick attributes, instance here:

$("#sls").append('<button onclick = "loadslide\'1\')" id = "slide_1">slide 1</button>');

it's missing opening parenthesis. reason syntax checks don't catch because you're putting code inside string. should not do.

since you're using jquery, how using .click(function() { ... }) instead of inline attributes? careful captured variables correct.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
