Please help me write this program in C language (printf / scanf... not <>)

Write a program that will calculate a person's weekly gross pay (gross pay is pay before taxes). A person who is paid by the hour receives weekly gross pay based on their pay rate ($/hr.) multiplied by the number of hours worked. (1) Display a prompt and get the pay rate (as a double). (1 pts)

(2) Display a prompt and get the hours worked (as an integer). (1 pts.)

(3) Display the weekly gross pay based on the inputs (3 pts.)

Ex:

Enter the pay rate: $10

Enter the number of hours worked: 12

Pay: $120.00

The program will ask the user to enter the pay rate of the person, followed by the number of hours worked, and will display the weekly gross pay.
