C symbol List

List of c‧ symbols

Mathematical Symbols:

Symbols	Explain	Example
+	Plus or positive	A = 1 + 2;//Results A = 3 A =-5; b = +a;//Results b = 5
-	Minus or negative value	A = 3-1;//results A = 2 A = 5; b =-a;//Fruit b =-5;
*	Multiplication	A = 2 * 3;//Results A = 6
/	Except	A = 6/2;//results A = 3
%	Remainder	A = 7 2;//results A = 1, 7 divided by 2, except 1 is the remainder
++	Original value plus 1	A = 1; b = ++a-5;//a plus 1 and then minus 5. b = a++-5;//a minus 5 and then 1.
--	The original value minus 1	A = 10; b =--a + 5;//a minus 1 and then 5. b = a--+ 5;//A first plus 5 minus 1.

sentence break:

Symbols	Explain	Example
>	Greater than	if (a > B)//If A is greater than B { }
>=	Greater than or equal to	if (a >= b)//If a is greater than or equal to B { }
<	Less than	if (a < b)//If A is less than B { }
<=	Less than or equal to	if (a <= b)//If a is less than or equal to B { }
==	Equal	if (a = = B)//If A and B are equal { }
!=	Not equal	if (A! = b)//If A and B are not equal { }

bit symbol:

Symbols	Explain	Example
!	No	if (! ( A > B))//if not a greater than B, the Bollinger bands are used { }
&&	And	if (a > B && C > D)//If a > B and C is greater than D, the Bollinger bands are used { }
||	Or	if (a > B | | c > D)//If a > B or C is greater than D, the Bollinger bands are used { }
True	Really	BOOL B = true;//Set a = True if (b = = true)//If A is true, the Bollinger value is used { }
False	False	BOOL B = false;//If a = False if (b = = false)//If A is false, the Bollinger value is used { }
~	Not	Reverse the bit patches for each bit, two-bit use int a = 5; Two-bit 00000000000000000000000000000101 int b = ~a; Results B is equal to the second 11111111111111111111111111111010
&	and	Two-position and bit-element use, the dual-azimuth element is 1, the result is 1 int a = 10;//a is equal to two bits 1010 int b = 12;//b equal to two-1100 int c = A & b;//c equal to two 1000
|	OR	Two bits and bits are used, only one bit is 1, which results in 1 int a = 10;//a is equal to two bits 1010 int b = 12;//b equal to two-1100 int c = A | B;//C is equal to the second level 1110
^	Xor	Two-position and bit-element use, the dual-azimuth element is 0, the result is 1 int a = 10;//a is equal to two bits 1010 int b = 12;//b equal to two-1100 int c = A | B;//C is equal to the second level 0110
<<	Move left	Binary and bit use, bit left-shifted 0 int a = 10;//a is equal to two bits 1010 A = a << 1;//a are equal to two 10100, a is equal to 20 Shift 1 per left to indicate the number multiplied by 2
>>	Move right	Binary and bit use, bit right shift 0 int a = 10;//a is equal to two bits 1010 A = a >> 1;//a are equal to two 0101, A is equal to 5 Every left shift is 1, which means the number is divided by 2, and the decimal point is no more.

specified symbol:

Symbols	Explain	Example
=	As	A = 1;
+=	Plus is equal to	A + = 1;//is a = a + 1;
-=	Minus equal to	A-= 1;//is a = A-1;
*=	The multiplication is equal to	A *= 1;//is a = a * 2;
/=	Except for	A/= 1;//is a = A/2;
%=	The remainder is equal to	A%= 1;//is a = a% 2;
??	Value type can be null	Normally, value type values cannot be set to NULL Int? A = null;//Such a declaration can be int b = a?? -1;//if a equals null then B equals-1, or B = a
&=	And so on	A &= 1;//is a = A & 2; , two-bit use, the reference bit symbol
|=	or equal to	A |= 1;//is a = a | 2., two-bit use, the reference bit symbol is stated
^=	XOR is equal to	A ^= 1;//is a = a ^ 2;, two-bit use, the reference bit symbol
<<=	Left SHIFT, etc.	A <<= 1;//is a = a << 2, and the second is used, the reference bit symbol is stated
>>=	Right-shift to	a >>= 1;//is a = a << 2;, two-bit use, the reference bit symbol says
