What is the grammatical content of a programming langu age? What are the basic control structures in structured progra mming? What are the characteristics of C language? What is the basic framework of C language program? What steps do you need to take to form a runnable C lang uage program? How to describe a simple algorithm with a flow chart? 1.1 A C Language Program Input 4 Output 24 Example 1-1 for factorial problem.Input a positive integer n, output n!. # Include <stdio.h>/* Compile preprocessing commands*/ Intmain (void) /* main function*/ { Int n; /* variable definition*/ Intfactorial (int n); /* function declaration*/ Scnf ("% d", & n);/* Enter an integer*/ Printf ("% d n", factorial (n);/* Call function to calculate factorial*/ Return 0; } Infactorial (int n) /* Defines a function for calculating n!*/ { Int i, fact = 1; For (i = 1; I <= n; I +) /* loops*/ Fact = fact * i; Return fact; } C program consists of functions There is and only one main functio n main 1.2 Programming and Programming Language  program    To solve a problem, people use computer-recognizable co de to arrange a series of processing steps. The execution process of a program is actually a process of processing the data expressed by the program. Programming Language   A function of expressing and processing data is provided. Require programmers to program according to language s pecifications 1.2 Programming and Programming Language Procedures and instructions  Functions of Programming Language  Grammar of Programming Language  Compiling and Programming Environ ment of Programs  Procedures and
