Experiment Name C + + simple programming-2 experimental date 2018-3-20 score Instructor Shan Department of Soft College professional embedded + soft-embedded grade 2017 Frequency (1) name Schhao Yang School number 20161334026
[TOC]

First, the purpose of the experiment

• Understanding and mastering the definition and use of functions in C + +
• Understanding the difference between value passing and reference passing during function calls in C + +
• Flexible, comprehensive use of C + + branch structure, loop structure and continue, break and other applications to solve the problem of programming.

II. Preparation of the experiment

Before the experiment, please preview/review the specified content around the following contents

• Definition and usage of functions in C + +
  Read and learn the 3.1 sections of the textbook, Study/review the following:
  • The syntax form of the function definition, function parameter and argument, return value function, function call form; function parameter
    Number of delivery methods (value passing and reference passing)
  • Specify Learning Examples: 3rd Chapter 3-1, example 3-4, example 3-11, example 3-12
• Use of the IF statement, switch statement, while statement, Do...while statement in C + + and its nested usage
• The use of continue statements and break statements in C + +

Iii. contents of the experiment

• Validation experiments
  • Run the textbook P68 example 3-4 source code, to understand the function declaration, function definition, function call method, to
    and parameters, arguments, the function of the return value, and the value passing process of the parameter.
  • Run the textbook P78 example 3-11 source code, P79 example 3-12 source code, observe the difference between the results of the operation, combined
    3.1.3 section Analysis, understanding and summarizing the difference between value passing and reference passing
• Programming experiments
  The following are implemented in C + + programming:
  • Exercise 2-28 (Textbook P63)
  • Exercise 2-29 (Textbook P63)
  • Exercise 2-32 (Textbook P63)
  • Exercise 2-34 (Textbook P63)

Iv. conclusion of the experiment

• Validation Experiment Section
  • function declarations and functions define the respective roles, the difference between the two;
    • A function declaration is used to declare a new function, such asint max(int a,int b);
    • A function definition refers to the occurrence of a function's contents, for exampleint max(int a,int b){return a>b?a:b;}
