嵌套if語句的語法如下:
if <expression 1>
% Executes when the boolean expression 1 is true?
if <expression 2>
% Executes when the boolean expression 2 is true
end
end
例如:
創建腳本文件並在其中鍵入以下代碼 :
a = 100;
b = 200;
% check the boolean condition if( a == 100 )
% if condition is true then check the following?
if( b == 200 )
% if condition is true then print the following?
fprintf('Value of a is 100 and b is 200\n' );
end
end
fprintf('Exact value of a is : %d\n', a );
fprintf('Exact value of b is : %d\n', b );MATLAB
執行上面示例代碼,得到以下結果:
Value of a is 100 and b is 200
Exact value of a is : 100
Exact value of b is : 200
擴展資料:
C語言提供了三種形式的if語句:
1、if(表達式)語句。
例如:
if(x>y)printf("%d",x);2、if(表達式)語句1 else 語句2。
例如:
if(x>y)printf("%d",x);
else?printf("%d",y);
3、在每個語句中,可以有多個語句,但需要加上大括號。
例如:
if(x>y){printf("%d",x);break;}百度百科—if語句
