cin >> i; - ️️The code above states that there will be a value inputed (allows the user to input a value)/ associated with i later on. For example it could be used in a way such as i++, if the input value of i is 1 the ++ will incrementally increase i by 1 thus making i 2. assuming that C and F are both declared as doubles, and F has a valid value. - ️️What's wrong with it is you're always going to get 0 because it is integer division and 5 does not go into 9 evenly. Yo...

Write the constructor for the Time class. It takes three integer arguments: the potential hour, minute, and second values for the Time object. The constructor should pass the individual arguments to the setHour, setMinute, and setSecond methods to initialize the data members. Time :: Time ( int newHr, int newMin, int newSec ) { setHour ( newHr ); setMinute ( newHr ); setSecond( newSec ); } Write the setHour method for the Time class. It takes an integer argument that will po...

Write a C++ statement that takes the digit character in the char variable ch and changes it to its integer representation and saves the result in the integer variable intVal. So if ch contains '4', then intVal should contain the value 4. Assume that ch and intVal have been properly declared. - ️️intVal = ch - '0'; What will happen if a char is cout'd as an int? - ️️the ASCII value of the character will be displayed What is the ASCII value of the character '1'? ...
