[Solved] Why does the testing condition has no effect

by

[ad_1] The problem is that you are taking sloppy English and translating it literally to create broken C++. When you say: the character is not ‘N’ or ‘n’ this, while commonplace, is wrong. For the same reason, your C++ code is wrong. You are comparing getche() to ‘N’ || ‘n’, an expression which applies boolean-OR … Read more

[Solved] What does “if (targetStr.indexOf(value) == -1) ” condition mean in the below program, so we get correct output [closed]
