Assignment 3: Reading from a File and using a multi-dimensional array

Write a C program to read from a file called "input.txt" information about 5 workers. Each line of input would contain two values respectively, an employee ID and the employee's monthly salary.

Assume that the data from the input file is stored in a format as shown in this example. Note: for testing purposes, the following data may not necessarily be used. It is just to give you an idea of the format of the data:

Sample contents of input.txt:
10 2000
20 6800
30 9700
40 1500
50 8000

Store the employee information into a 2D array. Assume that the data types are as follows: id (integer data type) and income (integer data type).

Read the information and store the 5 employee records into the 2D array.

Use a function that prints the sum of all income of workers.

Create another function that prints the number of workers who has an income of greater than $5000 and also the ID and income of each worker who has an income of greater than $5000.

Sample output printed to the screen:
Sum of all incomes: $24500
3 Workers have an income of greater than $5000:
20 $6800; 30 $9700; 50 $8000
