C++ Looping and Data Type Corrections

This set of flashcards covers key programming errors in C++ code, focusing on loops, logical operators, and data types.

Loop enumeration issue

In the original code, the index used in the array loop was 'j' instead of 'i', and it should iterate until 'i<7'.

Infinite loop condition

The loop runs forever because 'j' was not incremented; it should be controlled by 'i' instead.

Do-while loop issue

The initial value of 'i' was set to 100, preventing the loop from executing; 'i' should start at 0 for 13 iterations.

Logical operator correction

The correct logical operator for 'and' in C++ is '&&'; using '=' is an assignment operator and causes errors.

Implicit conversion in output

The variable 'a' is declared as an int, causing it to print 12 instead of 12.456, which is due to implicit conversion dropping the decimal.

Explicit conversion example

Using 'static_cast(num1)' converts an int to a double for precise arithmetic.
