In this C++ tutorial, you will learn the syntax of For loop, its algorithm, flowchart, then some examples illustrating the usage of it. Later in the tutorial, we shall go through Infinite For Loop and Nested For Loop. C++ For Loop For Loop can execute a block of statements in a loop ...
// for_statement5.cppintmain(){inti =0;// hidden by var with same name declared in for loopfor(inti =0; i <3; i++ ) {}for(inti =0; i <3; i++ ) {} } 此行爲更精確地模擬在for迴圈中所宣告之變數的標準行為,這會要求在for迴圈中宣告的變數於迴圈結束後超出範圍。 在for迴圈中...

The range-based for statement has a syntax that looks like this: for (element_declaration : array_object) statement; When a range-based for loop is encountered, the loop will iterate through each element in array_object. For each iteration, the value of the current array element will be ...
