With static variable statics , the factorial value of 1 to 5 is output. Solution: Program:#include int FAC (int n){static int f=1;f = f*n;return F;}int main (){int i;for (i = 1; I {printf ("%d!=%d\n", I,FAC (i));}return 0;}Results:1!=12!=23!=64!=245!

A program is a sequential sequence of instructions written to allow a computer to perform a task.C language is characterized by: structured, concise language, powerful, good transplant.Because of good transplant, so the majority of single-chip

instance constructs and reference typesThe previous chapters have actually written about the construction of reference types:First of all, of course, in the heap, allocate memory for the instance object of the reference type, and then initialize the

When you are programming, you often need to save the information that the program runs, so the concept of "variables" is introduced in C #. Some of the values in the program cannot be changed, which is called "constants".1 variablesThe so-called
