I'm trying to master printf, but I'm having trouble concatenating values.

Hi. I'm trying to concatenate 3 intergers, but I'm getting an error that says I'm missing a closing parentheses before a numeric constant. Here's the code:

Code:

---

#include<stdio.h>
#include<stdlib.h>
//printf_Concatenation.c

int main()
{
    puts("Integers:");
    printf("As easy as %d, %d, and %d!"1,2,3);
    printf("The first number is %d, the second number is %d, and the third number is %d."1,2,3);
   
    puts("Strings:");
    printf("You are the %s link. Goodbye!\n","weakest");
   
    puts("Floating-Point Values and/or Fractions:");
   
    puts("Single Chars:");
   
    puts("Percentage");
    printf("I got %d%% on my C programming exam!\n",99);
}

The error for line 9 says:
9 87 C:\Dev-C_Projects\printf_Concatenation.c [Error] expected ')' before numeric constant

You forgot a comma, i.e., this:

Code:

---

printf("As easy as %d, %d, and %d!"1,2,3);

---

should have been:

Code:

---

printf("As easy as %d, %d, and %d!", 1,2,3);
