C Language Basic Three

sequence of program execution;

1. Sequential structure

2. Conditional structure, if conditional structure, IF...ELSE conditional structure, multiple if conditional branching structure (if...elseif). else) and the switch conditional structure

3. Loop structure: Do....while loop, while loop, for loop

Operator:

Arithmetic operators (categorized by operands)

1. Unary operator ++,--

2. Two-dollar operator; +,-,*,/,% (modulo or remainder)

Assignment operator: =

Compound assignment operator; +=,-=,*=,/=.%=

Comparison operators: Comparing the size relationships of numeric values (<,>,<=,>=,!=,==)

Logical operators: With && or | | Non -!

with (and): Multiple conditions at the same time for true results to be true =è a false than false

or (OR): in multiple conditions as long as one condition is true, its structure is true =è true

Non- ( take counter ): It's not true, it's not fake.

If condition structure: Executes the statement within its curly braces if the condition is established

if (condition) {

Statement

}

Example:

int A;//DECLARE variable

printf ("Please enter Age");//Output

scanf ("%d", &a);//input

if (a>=18) {//Judging condition

printf ("You are already an adult");

}if (a<18) {

printf ("Minors");

}

IF...ELSE Conditional structure: Judge the condition to execute its if under curly brace statement, otherwise execute else inside statement

if (a>=18)

{

printf ("adult");

}else{

printf ("Minors");

}

Determine whether the number of daffodils;

int num,ge,shi,bai,he;//declares integer input values, bits, 10 bits, hundred, and

printf ("Please enter a three-digit number");

scanf ("%d", &num);//input%d integer placeholder & outlaw Value

Digit Three square + 10 bit three square + hundred three times for Narcissus number

1. Get the digit

ge=num%10;

2. Get 10-bit

shi=num/10%10;

3. Get hundreds

bai=num/100;

He=ge*ge*ge+shi*shi*shi+bai*bai*bai

if (he=num) {//Determine if the number of daffodils is

printf ("%d daffodils;", num);

}else{

printf ("%d is not narcissus number;", num);

}

Implement the Scissors game : user A and user B Enter the punches separately (0: scissors , 1: Stone , 2: cloth )

int usera,userb;

/1. Get users separately A and User B The punch out of the

printf ("Please a player punch:0 for Scissors,1 for Stone, 2 for cloth \ n");

printf ("Please User A punch:");

scanf ("%d", &usea);

printf ("Please User B punch:");

scanf ("%d", &USEB);

2. based on user A and User B comparison of the punches made

//UserAwin==> (Usera:0 (Scissors) &&UserB:2 (cloth));(UserA:1 (Stone) &&Userb:0 (Scissors));(UserA:2 (cloth) &&UserB:1 (Stone))

if ((usera==0&&userb==2) | | | (usera==1&&userb==0) | | (usera==2&&userb==1))

{

printf ("User A You Won");

Draw ==> user a== user B

if (Usera==userb)

}

{

printf (" really bad, draw ~~~~~~~~~\n");

}

//UserBwin==> (Usera:0 (Scissors) &&UserB:1 (Stone));(UserA:1 (Stone) &&UserB:2 (cloth));(UserA:2 (cloth) &&Userb:0 (Scissors))

if ((usera==0&&userb==1) | | | (usera==1&&userb==2) | | (usera==2&&userb==0))

{

printf ("User B wins ");

}
