c# 賦值運(yùn)算符

Assignment operators (Assignment (=) and compound assignments (+=, -+, *=, /=, %=)) are used to assign the value or an expression's result to the left side variable, following are the set of assignment operators,

賦值運(yùn)算符(Assignment( = )和復(fù)合賦值( + = ， -+ ， * = ， / = ， ％= ))用于將值或表達(dá)式的結(jié)果賦給左側(cè)變量，以下是賦??值運(yùn)算符集，

"=" – it is used to assign value or an expression's result to the left side variable

“ =” –用于將值或表達(dá)式的結(jié)果分配給左側(cè)變量

"+=" – it is used to add second operand to the existing operand's value and assigns it back (a+=b is equal to a=a+b)

“ + =” –用于將第二個(gè)操作數(shù)添加到現(xiàn)有操作數(shù)的值并將其賦值回去(a + = b等于a = a + b)

"-=" – it is used to subtract second operand from the existing operand's value and assigns it back (a-=b is equal to a=a-b)

“-=” –用于從現(xiàn)有操作數(shù)的值中減去第二個(gè)操作數(shù)并將其賦值回去(a- = b等于a = ab)

"/=" – it is used to divide second operand from the existing operand's value and assigns it back (a/=b is equal to a=a+b)

“ / =” –用于將第二個(gè)操作數(shù)與現(xiàn)有操作數(shù)的值相除并將其賦值回去(a / = b等于a = a + b)

"*=" – it is used to multiply second operand with the existing operand's value and assigns it back (a*=b is equal to a=a*b)

“ * =” –用于將第二個(gè)操作數(shù)與現(xiàn)有操作數(shù)的值相乘并賦值回去(a * = b等于a = a * b)

"%=" – it is used to get the remainder by dividing second operand with the existing operand's value and assigns it back (a%=b is equal to a=a%b)

“％=” –用于通過(guò)將第二個(gè)操作數(shù)除以現(xiàn)有操作數(shù)的值來(lái)獲得余數(shù)，并將其賦值回去(a％= b等于a = a％b)

Example:

例：

Input:int a = 10;int b = 3;//operations & outputsa = 100; //value of a will be 100a += b; //value of a will be 103a -= b; //value of a will be 100a *= b; //value of a will be 300a /= b; //value of a will be 100a %= b; //value of a will be 1

C# code to demonstrate example of assignment operators

C＃代碼演示賦值運(yùn)算符的示例

// C# program to demonstrate example of // assignment operators using System; using System.IO; using System.Text;namespace IncludeHelp {class Test{// Main Method static void Main(string[] args){int a = 10;int b = 3;Console.WriteLine("a: {0}", a);a = 100; //assigmentConsole.WriteLine("a: {0}", a);a += b;Console.WriteLine("a: {0}", a);a -= b;Console.WriteLine("a: {0}", a);a *= b;Console.WriteLine("a: {0}", a);a /= b;Console.WriteLine("a: {0}", a);a %= b;Console.WriteLine("a: {0}", a);//hit ENTER to exit the programConsole.ReadLine();}} }

Output

輸出量

a: 10 a: 100 a: 103 a: 100 a: 300 a: 100 a: 1
