How do I properly 'printf' an integer and a string in C?

Question

I have the following code:

char *s1, *s2;
char str[10];

printf(\"Type a string: \");
scanf(\"%s\", str);

s1 = &str[0];
s2 = &str[2];

printf(\"%s\\         


        

Answer 1

You're on the right track. Here's a corrected version:

char str[10];
int n;

printf("type a string: ");
scanf("%s %d", str, &n);

printf("%s\n", str);
printf("%d\n", n);

Let's talk through the changes:

1. allocate an int (n) to store your number in
2. tell scanf to read in first a string and then a number (%d means number, as you already knew from your printf

That's pretty much all there is to it. Your code is a little bit dangerous, still, because any user input that's longer than 9 characters will overflow str and start trampling your stack.
