title: printf ignores single backslash '\'
body: <p>I have this code :</p>
  
  <pre><code>int main(int argc, char * argv[])
  {
  int i;
  printf("%d%s",argc,argv[1]);
  return 0;
  }
  </code></pre>
  
  <p>If I run this code as <code>a.out a\=b=</code>.I am using <code>C-shell</code></p>
  
  <p>Its output is "<code>a=b=</code>" is there any way that its output can be changed to "<code>a\=b=</code>".</p>
