WebAs explained in the Variables chapter, a variable in C++ must be a specified data type: Example int myNum = 5; // Integer (whole number) float myFloatNum = 5.99; // Floating point number double myDoubleNum = 9.98; // Floating point number char myLetter = 'D'; // Character bool myBoolean = true; // Boolean string myText = "Hello"; // String WebOct 25, 2013 · But an int takes 4 bytes. How many addresses does this int take? Does it still have only 1 address or does it have 4? For example : char c = 'A'; //Address at 0xdeadbeee int i = 45846; //Address at 0xdeadbeef int* iPtr = &i; iPtr++; //Address at 0xdeadbef3 now What happens with the addresses between 0xdeadbeef and 0xdeadbef3?
