Awk Script Problem

For all awk problems, ensure that you have the proper shebang so that they can be run with only an input file as input, and no flags or options.

In a file called col1, write an awk script that will print the first column of a given file with the default separator.

In a file called computeExpense.awk, write an awk script that will take a comma separated file where the first column is the users name, the second is their hourly rate, and the third is their hours worked. Calculate the total money spent in salaries. (sum all of column 2 * column 3). An example file is:

Lois Lane,25,20 John Jones,15,5 Mike Smith,80,40

In a file called percentWriteIn, write an awk script that will compute and print the percent of votes where the name field is "Write In" from a file in the format of a .txt file.
