When using if statements, you will often wish to check multiple different conditions. You must understand the Boolean operators OR, NOT, and AND. The boolean operators function in a similar way to the comparison operators: each returns 0 if evaluates to FALSE or 1 if it evaluates to TRUE. ...
A method for optimizing if statements in a program includes obtaining, by a processing device, for each of conditional expressions of a plurality of if statements in the program, a set of conditional expressions having an inclusion relation; computing, for each of the set, a position with low...

Moving on up the grade levels, you can move on up the coding complexity too with If-Then-Else statements. For example, the Programmer commands “If I raise my right arm, Then you raise your left arm, Else raise your right foot.” So if he just stands there and does nothing, the ...
Swift Expressions, Statements and Code blocks Swift if, if...else StatementIn computer programming, we use the if statement to run a block code only when a certain condition is met. For example, assigning grades (A, B, C) based on marks obtained by a student. if the percentage is above...
If it evaluates to be true, then the set of statements following that condition will be executed and then the program will come out of that particular block and execute the next set of statements. 在这里,变量“ a”被初始化为10。然后,使用if块,条件是检查a是否大于8。 如果评估结果为true,则...

Similarly, shell functions can return an exit status by including an integer argument to thereturn command. If we were to convert the script above to a shell function to includeit in a larger program, we could replace the exit commands with return statementsand get the desired behavior: ...
