title: What's the standard definition of printf in C?
body: <p>What is the function definition of the <code>printf()</code> function as defined in the standard C library?</p>
  
  <p>I need the definition to solve the following question:</p>
  
  <blockquote>
    <p>Give the output of the following:</p>
  
  <pre><code>int main()
  {
     int a = 2;
     int b = 5;
     int c = 10;
     printf("%d ",a,b,c);
     return 0;
  }
  </code></pre>
