Answer to Question #106518 in C++ for Haroon hanif

Question

We use a string lenght 50

And we want to add two string values


And stores in 3rd value


We make a function void in

And void show


Since 1st and 2nd function can input values from void in


And show it


But 3rd function has no value input from user


And it will not show value of 3rd beacuse we didn't input value from user


And we use


Constructor

Str[0]=`\0`;



So it can successfully show the value
Without print any other characters on screen.


If we not use it

We shows characters on output screen.



Why,i cant understand.

Char [50];

public:

Str[0]=`\0`;


Why we are using it.


And tells me which should i follow.
