check the logical condition using if statement if (a < 20 ) then !if condition is true then print the following print*, "a is less than 20" end if print*, "value of a is ", a end program ifProg When the above code is compiled and executed, it produces the following result −...
In certain situations, the second contained sub-statement of an "if-then-else" statement needs to be another "if-then-else" statement. The result is a nested "if-then-else" statement. Some times, you may have many "if-then-else" statements nested. Here is an example of 5 "if-then-...
IFconditionTHENstatement;ELSEstatement;ENDIF; 1. 2. 3. 4. 5. 其中,condition是一个逻辑表达式,如果表达式的值为TRUE,则执行IF后面的语句;如果表达式的值为FALSE,则执行ELSE后面的语句。 插入数据操作 在MySQL存储过程中,我们可以使用INSERT语句来向数据库中插入数据。INSERT语句的基本语法如下: ...
How does let in for loop work? I understand how "var" works and I'm quite used to it - the scope is functional. However the let statement is far from clear. I understand is has block scope, but why does THAT matter in the......
