As with all variables, it is important to initialize array elements to some known value before using them. Just as with structures, as we saw in Chapter 9, Creating and Using Structures, we can initialize an array in several different ways.
The most basic way to initialize an array is to set all of its values to the same value at the time of definition. We set all the array elements to the same value as follows:
int anArray[10] = {0};
double wheelTread[ getNumberOfWheels( tricycle ) ] = { 1.5 };
All the values of each array are set to the same value given within { and }. All 10 values of anArray are set to 0. All three values of wheelTread are set to 1.5. However, we could have set them all to a constant value, a variable, or the result of an expression. We can change the value of each element as needed later.
To set each element to different values during initialization, each element's value can be specified between {...
