title: warning: format ‘%d’ expects type ‘int *’, but argument 2 has type ‘int’
body: <p>So I'm new to C and am having trouble with whats happening with this warning. What does the warning mean and how can i fix it.
  The code i wrote is here:</p>
  
  <pre><code>void main(void)
  {
    char* name = "";
    int age = 0;
    printf("input your name\n");
    scanf("%s\n", name);
    printf("input your age\n");
    scanf("%d\n", age);
    printf("%s %d\n", name, age);
  
  }
  </code></pre>
