c - why does my netpay display no answer? -


i writing code payroll check. function asks user hours worked , hourly pay. function accepts hours , rate arguments , calculates , returns grosspay. send grosspay function calculate , return payrolltax(.22). call function accept grosspay , taxes arguments , return netpay. last send data function display values (totalhours, hourlyrate, grosspay, tax, , netpay). netpay displaying me 0 , tax displaying wrong answer. can tell me went wrong?

/* payroll check */ #include <stdio.h>  float askhoursworked(); float askhourlyrate(); float calculategrosspay(float hours,float rate); float calculatepayrolltax(float grosspay); float calculatenetpay(float grosspay,float tax); float displayallvalues(float ,float ,float,float ,float );  int main() {       float hours;       float rate;       float grosspay;       float tax;       float netpay;       float values;        hours=askhoursworked();       rate= askhourlyrate();        tax=  calculatepayrolltax( grosspay);       netpay= calculatenetpay( grosspay,tax);       grosspay=calculategrosspay( hours,  rate);        values= displayallvalues( hours, rate, tax, grosspay, netpay);        return 0; }    float askhoursworked()  {         float hours;        printf("\n please enter hours worked \t");        scanf("%f",&hours);         return hours;  }   float askhourlyrate()  {      float rate;     printf("\n please enter payrate \t");     scanf("%f",&rate);      return rate;   }  float calculategrosspay(float hours,float rate) {     float grosspay;     grosspay=hours*rate;      return grosspay; }  float calculatenetpay(float grosspay,float tax) {     float netpay;     netpay=grosspay-tax;      return netpay; }  float calculatepayrolltax(float grosspay) {     float tax;     tax=grosspay*.22;      return tax; }  float displayallvalues(float hours,float rate,float tax,float grosspay,float netpay) {     printf("\n total hours %.2f",hours);     printf("\n hourly rate  %.2f",rate);     printf("\n grosspay %.2f",grosspay);     printf("\n taxes %.2f",hours);     printf("\n netpay %.2f",netpay); }

in c language, use single pass compiler. means here, order matters most. calculating grosspay @ last. , using in calculation of netpay , taxes.

here right way..

 hours = askhoursworked ();  rate = askhourlyrate ();  grosspay = calculategrosspay (hours, rate);  tax = calculatepayrolltax (grosspay);  netpay = calculatenetpay (grosspay, tax);

check on online compiler

edit have printed output in wrong manner.

  printf ("\n total hours %.2f", hours);   printf ("\n hourly rate  %.2f", rate);   printf ("\n grosspay %.2f", grosspay);   printf ("\n taxes %.2f", tax);   printf ("\n netpay %.2f", netpay);

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
