dataType array_name[arraySize]; Example:- Declare an array int student_marks[20]; char student_name[10]; float numbers[5]; In the last example, we declared an array “numbers” of the type int. Its length is 5. In other words, it can store 5 integer numbers. ...
Difference in Behavior for Input Arrays of Complex Numbers If the input arrayAis an array of complex numbers, and some of the elements have imaginary parts equal to zero, then callingarrayfunand indexing into the array can lead to different results. Thearrayfunfunction always treats such numbers ...
