Logical operators

&& And

|| OR

! Not

Assignment operatorsMeaning Example Operator

x = 5 x = 5 =

x =x+5 x += 5 =+

x = x-5 x -= 5 =-

x = x*5 x *= 5 =*

x = x/5 x /= 5 =/

Decision Making Structures

If statement

If else statement

If… else if statement

If statementif (condition){Statements will execute if the condition is true.}

Condition CodeTrue

False

End

End

If…. else statementif (condition){Statements will execute if the condition is true}

else{Statements will execute if the condition is false}

Condition CodeTrue

False

Code

Else

End

End

If …else if statementsif (condition1){Executes when condition1 is true}

else if(condition2) {Executes when condition 2 is true}Else{Executes when condition 1 and 2 arefalse}

Condition

Code

True

FalseElse if EndCondition

False

Code

True

End End

Loops

Initialization expression

Conditionalexpression

Update expression

For and while loop

For(int x=0;x<5;x++){ //loop body}

int x=0;While(x<5){ // loop body x ++;}

Do… while loop

int x=0;do{x++; //loop body}while(x<5);
