I am currently studying c programming, but I'm at a very basic level. So for practice I made a program that reads a string and inverts it. I want to know if the code is readable and how can I improve it.

 strlen(s) - 1 is used. We don't need to read all contents

 its content is stored in aux[n]. In this case, from zero to the
 size of s[]'s string - 1. Minus 1 is used because we read it from ZERO,
 not i. */
 for (i = strlen(s) - 1, n = 0; n < strlen(s), i >= 0; i--, n++) {
 aux[n] = s[i];
 }
 printf("Included with the super mojo from the string inverter, ");
 printf("this is the result: ");
 //This for loop reads all the content from the aux array, and print it.
 for (j = 0; j < strlen(s); j++) {
 printf("%c", aux[j]);
 }
}
int main(void)
{
 char string[NUM];
 printf("\nWelcome to the super, duper string inverter!\n");
 printf("If you want to see some magic, enter a string:\n>");
 gets(string); //Reads the string.
 //Now, we only need to call the function with string[] as a parameter.
 invert(string);

I'm am currently studying c programming, but i'm still in a very basic level. So, just for practice, I made a program that reads a string the invert it. I want want to know if the code is readable, how can I improve it... Please, remember, i'm very newbie in programming.
