C++ Programming Fundamentals: Arrays, References, Structures, and More
Arrays can only contain the same data type. Data types: bool, char, int, float, double. To declare an array: type arrayName [ arraySize ]; — This is called a single-dimension array. To declare a 10-element array called balance of type double, use this statement:
Double balance[10];
—
You can initialize C++ array elements either one by one or using a single statement:
Double balance[5] = {1000.0, 2.0, 3.4, 17.0, 50.0};
— Or you can do this this way:
Double balance[] = {1000.0, 2.0, 3.4, 17.0, 50.0}
