Find the efficiency of the worker.

Write a C program in a company, worker efficiency is determined on the basis of the time required for a worker to complete a particular job. If the time taken by the worker is between 2 - 3 hours, then the worker is said to be highly efficient. If the time required by the worker is between 3 - 4 hours, then the worker is ordered to improve speed. If the time taken is between 4 - 5 hours, the worker is given training to improve his speed, and if the time taken by the worker is more than 5 hours, then the worker has to leave the company. If the time taken by the worker is input through the keyboard, find the efficiency of the worker. 
   
 #include<stdio.h> 
 #include<conio.h> 
 void main() 
 { 
 float hours; 
 clrscr(); 
 printf("Enter the number of hours worker takes to finish the job:"); 
 scanf("%f",&hours); 
 if(hours>=2&&hours<=3) 
 printf("\nWorker is highly efficient"); 
 else 
 { 
 if(hours>=3&&hours<= 4) 
 printf("\nWorker is ordered to improve his efficiency"); 
 else 
 { 
 if(hours>=4&&hours<=5) 
 printf("\nWorker should be given training to improve his efficiency"); 
 else 
 printf("\nWorker should leave the company"); 
 } 
 } 
 printf("\nPress any key to exit."); 
 getch(); 
 } 
   
 OUTPUT:   
   
 Enter the number of hours worker takes to finish the job: 4 
 Worker is ordered to improve his efficiency 
 Press any key to exit.
