看懂這個LR腳本，再也沒有看不懂的LR腳本了
LoadRunner自帶的訓練的飛機票網站的例子中，有一個頗有意思的流程，以下： 首先登錄機票系統，而後查詢從哪裏到哪裏的機票。而後系統會給你4張推薦票。 選擇一張機票，後就能夠支付而後完成機票的預約和購買了。 測者相信全部在用LoadRunner的人對這個流程都不陌生，很熟悉。那麼今天測者提出一個問題，我想一個腳本購買推薦的4張飛機票。該如何處理對應的測試腳本呢？javascript

特別點的解釋 首先，LoadRunner是ansi C語言，所以變量要放到函數的開頭聲明（C語言的變量）。其次，在for循環中，咱們看到了幾回sprintf，那麼這裏了測者會詳細說一下，第一次 （假設當前i=0），sprintf(temp,"{flytype_%d}",i+1);，其中「{flytype1}」的含義（包含雙引號），是將一個指向了存有flytype_1值的內存地址的指針指向的值賦值給了temp。也就是temp指向了一段存儲了fltype_1值的內存。sprintf(tempfly,"%s",lrevalstring(temp));將flytype_1這個指針指向的內存地址存儲的值賦給了tempfly，也就是說tempfly和flytype_1這兩個指針都指向相同內存地址，這段地址存儲的就是關聯出來的第一張機票的ouboundFlight值。java
