Hi

#include<stdio.h>
main()
{
char s[]="Taiwan University.";
float a;
scanf("%f",&a);
printf("%f",a);
printf("input string:");
gets(s);
puts("%s",s);
}

After compiled by Visual Studio, the above program can input a.
But after it shows a, then I cannot enter s string.
Why?

Just to add to the other posts, your string literal "Taiwan University." is of type const char *. You should not assign anything to it, because it might be stored in a place in memory to which your program cannot write, at which point it will crash (this idea can be summarized easily: never cast away the constness of string literals). Have a look at malloc() and free() instead, or just declare an array of char, eg. char s[81].

If you're feeling a bit overwhelmed with all these replies, being a newbie, note that strings are much more complicated than other variables in C.
