Please help me, I already made a programm it run good if i only input a first name but if i input first and last name it did'nt work properly
here is the program i made and the output of the program

PROGRAM

#include <stdio.h>
#include <conio.h>
#include<math.h>

char a,name;
double x,y,z,b,c,d,late,ot,ot1,ot2,xin,wrk,grs,tax,phil,sss,td,net,net1;
main()
{
  char name[20];
  printf("Employee Name:\t\t\t");
  scanf("%8s", &name);
  printf("Number of hours work:\t\t");
  scanf("%lf", &x);
  printf("Extra hours work (OT):\t\t");
  scanf("%lf", &y);
  printf("Number of hours late(UT):\t");
  scanf("%lf", &z);
  printf("Rate per hour:\t\t\t");
  scanf("%lf", &b);
  printf("Food deduction:\t\t\t");
  scanf("%lf", &c);
  printf("Extra income:\t\t\t");
  scanf("%lf", &d);
  a=(char)name;
  printf("\n\tEmployee Name:  %s\t\t",name);
  scanf("%c", &name);
  late=(float)z*b;
  printf("\n\tUndertime pay:   %5.2lf\t\t",late);
  ot1=(float)b*0.04*y;
  ot2=(double)y*b;
  ot=(double) ot1+ot2;
  printf("\n\tOvertime pay:   %5.2lf\t\t",ot);
  xin=(float)d;
  printf("\n\tExtra income:    %5.2lf\t\t",xin);
  ot1=(float)b*0.04*y;
  ot2=(double)y*b;
  ot=(double) ot1+ot2;
  wrk=(double)x*b;
  grs=(double)ot+wrk;
  printf("\n\tGross pay:      %5.2lf\t\t\t",grs);
  ot1=(float)b*0.04*y;
  ot2=(double)y*b;
  ot=(double) ot1+ot2;
  wrk=(double)x*b;
  grs=(double)ot+wrk;
  tax=grs*.15;
  phil=grs*.025;
  sss=grs*.04;
  late=(double)z*b;
  td=(double)tax+phil+sss+c+late;
  net1=(double)grs-td;
  net=(double)net1+d;
  printf("\n\tNet pay:       %5.2lf\t\t\t",net);
  
  getch();
}

WHEN I INPUT ONLY FIRSTNAME ONLY IT WORKS PROPERLY

Employee Name: mark
Number of hours work: 240
Extrea hours work (OT): 52
Number of hours late(UT): 2
Rate per hour: 100
Food deduction: 300
Extra income: 1250

Employee Name: mark
Undertime pay: 200.00
Overtime pat: 5408.00
Extra income: 1250.00
Gross pay: 29408.00
Net pay: 23835.28


----------------------------------------------

BUT WHEN I INPUT BOTH FIRST AND LAST NAME THIS HAPPENED

Employee Name: mark gwapo
Number of hours work: Extrea hours work (OT): Number of hours
late(UT): Rate per hour: Food deduction:
Extra income:

Employee Name: mark
Undertime pay: 0.00
Overtime pat: 0.00
Extra income: 0.00
Gross pay: 0.00
Net pay: 0.00

scanf("%8s", &name); //???
Think about the %8 for this line.

already change to another value or remove that 8 but i still got an error in output

scanf() cannot read two words easily. And it's only slightly less dangerous than gets() .

Look up fgets() . You will have to check the last character for \n and remove it, but it's safer and easily reads the entire line.

If you want two values, you will need to use two variables in the scanf.

scanf("%8s %8s", &strFirstName, &strLastName);

...or use gets()

If you want two values, you will need to use two variables in the scanf.

scanf("%8s %8s", &strFirstName, &strLastName);

...or use gets()

Never NEVER **NEVER** recommend gets() !!! Didn't you read the previous post? It's dangerous!
