Practice Assignment

(squares1.c)

Information

  1. Write a program that prints out the numbers 1 to 20 and also the numbers squared. It should look like this: 
       Value     Value*Value
------------------------
     1:           1
     2:           4
     3:           9
     4:          16
     5:          25
     6:          36
     7:          49
     8:          64
     9:          81
    10:         100
    11:         121
    12:         144
    13:         169
    14:         196
    15:         225
    16:         256
    17:         289
    18:         324
    19:         361
    20:         400
    Notice that all of the numbers are right-justified. Each number in the first column takes up 6 characters, and each number in the second column takes up 12 characters. Your output must match exactly. Don't forget the colon after the number in the first column.

    Approximate number of lines of code: 6.

    The name of the file should be squares1.c and the command to compile it will look like this: 

    gcc -Werror -Wall -Wextra -ansi -pedantic squares1.c -o squares1 -O2 -Wno-unused-result
    output-squares1.txt
