#Mastery<\/a>27<\/p>\n Inputs have to be validated before allowing any kind of processing or operations to be performed on it. This is extremely important because , an unhandled wrong input \u00a0might have the complete ability to crash a system. \u00a0C++ has some \u00a0good \u00a0validation techniques that \u00a0can be used to validate most kind of inputs. This post \u00a0discusses some of the techniques and its shortcomings and \u00a0what could be done to improve the quality of validation.<\/p>\n Now, consider a program has to accept only integer inputs and reject all the others. So, the developer would have declared to store the integer value in say\u00a0\u201cint a;\u201d<\/strong>. So\u00a0\u201ca\u201d<\/strong>\u00a0will store the input value.<\/p>\n When the user input is accepted using the\u00a0\u201ccin>>a\u201d<\/strong>\u00a0statement, we can use the inbuilt methods surrounding the\u00a0\u201ccin\u201d<\/strong>\u00a0\u00a0statement to test its status.<\/p>\n #TC<\/a>1017<\/p>\n<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
