gruntjs - Parameters binding in grunt tasks -


i have problem grunt tasks:

 watch: {       jshint: {         files: ['gruntfile.js', '<%= version %>/src/**/*.js', '<%= version %>/src/*.js'],         tasks: ['jshint', 'concat', 'uglify'],          options: {           livereload: true         }       }     },

i call in function 

grunt.registertask('server', 'a task runs server', function(version) {     if (arguments.length === 0) {       grunt.log.writeln("please specify version in arguments (grunt "+this.name+":version)");     } else {       grunt.log.writeln(this.name + ", " + version );       grunt.config.set('version', version);       grunt.task.run(['jshint', 'concat', 'uglify', 'open', 'connect', 'watch']);      }   });

the problem watch task can see version tasks in watch don't bind version - here 

tasks: ['jshint', 'concat', 'uglify'],

outcome:

0.1\src\myjs.js" changed. \src\new.js cannot write file

the solution call 

watch: {       jshint: {         files: ['gruntfile.js', '<%= version %>/src/**/*.js', '<%= version %>/src/*.js'],         tasks: ['jshint:<%= version %>', 'concat', 'uglify'],          options: {           livereload: true         }       }     },

with 'jshint:<%= version %>'

don't know why happens works

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.
