Gets puts

Question

#include <stdio.h>
int main() {
char a[100];
gets(a);
printf("You entered: ");
puts(a);
return 0;
}
Can anyone help me with this. The output Displaying error

Answer 1

It's running, just showing warnings that brainless me can't fix.

Answer 2

"gets()" is a deprecated function! Use "fgets()" instead:
fgets(a, 100, stdin);
