C++

1. A function declaration is the function that appears throughout the program, and the function definition determines the function.2. A formal parameter is used in a defined function to accept the arguments passed when the function is called;

1.(1)#include using namespace Std;int main (){char i;coutwhile (true){cin>>i;if (i== ' A ')coutelse if (i== ' D ')coutelse if (i== ' S ')coutelse if (i== ' Q ')Break}return 0;}(2)#include using namespace Std;int main (){char i;coutwhile

Iv. conclusion of the experiment1.① function declarations and functions define their respective roles, the difference between the two;function declaration:int Fun (intint b);function definition:int Fun (int A,int b) { int C; C=a+b;

1. Characteristics of C languageGet used to lowercase letters, high case sensitivityDo not use line numbers, no program line conceptYou can use blank lines and spacesCommonly used camel-shaped writing format2. One of the qualities of a good C

Four1.(1), the function declaration represents a function, the function definition represents a function and its implementation of the process, the difference is that the function declaration is only the head of the function, and the function is

1. Built-in functions: Embed the code of the called function into the main function at compile time.Example: #include using namespace Std;inline int max (int a,int b,int C){if (b>a) a=b;if (c>a) a=c;return A;int main (){inti=7,j=10,k=25,m;M=max (I,J,

C # operators are divided into: arithmetic operators, relational operators, logical operators, bitwise operators, assignment operators, other operators1. Arithmetic operators: + 、-、 *,/,%, + + 、--2. Relational operators: = =,! =, >, =3. Logical

Constants are fixed values that do not change during the execution of the program. Constants can be any basic data type, such as Integer constants, floating-point constants, character constants, string constants, and enumeration constants.Constants
