In computer science, afor-loop(or simplyfor loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly。(作用:介绍了for循环是什么?) A for-loop has two parts: a header specifying the iteration, and a body which is executed once per iteration. (...

So if I put the else inside the second for loop it will print some values multiple times: Lets asume i is 0 and j is 0: Therefore the result is: "hd12459 is not found in v2" In the next step i ist still 0 but j is 1 which brings the same result: "hd12459 is not found in...

else{; replace `x' = `x'[`i']-`x'[`j'] in `i'; local j = 3; }; }; }; Whenever I try running this I get an error on my if statement, where Stata interprets "< 3" as a variable name. Any suggestions for loops
In Python, you can specify an else statement to a for loop or a while loop. The else block is executed if a break statement is not used.
if表达式 if 表达式允许根据条件执行不同的代码分支。你提供一个条件并表示 “如果条件满足,运行这段代码;如果条件不满足,不运行这段代码。” 无返回值执行: 代码语言:javascript 复制 fnmain(){letnumber=6;ifnumber<10{println!("condition was true");}else{println!("condition was false");}} ...
