title: how to comb through an input (equation) and grab variables, disregarding whitespace? (scanf()), (arrays)
body: <p>For my C program, the user enters in "aY + b = c" where a, b, and c are int values and Y is a "symbolic constant."</p>
  
  <p>How does one make it so that "aY+b=c" works as well as "aY   + b =   C" works? Basically, I am unsure of how to utilize scanf() so that I can grab my variables a,b, and c from the user input no matter how many spaces the user decides to input.</p>
  
  <p>Thanks!</p>
