Introduction to C-Programming As seen in ENGS 20

Up to this point we have been using singular data types, such as

int i, j, k;

float x, y, z;

double u, v, w;

Often situations arise in which it is more natural to store a collection of values together in a single variable.

We will first focus on storing integers in an array. For example, we may wish to store all students’ grades on an exam or the coordinates for an object or the values of a function at regular intervals, etc.

An array (think of a collection of data items of the same type) is just what we need to accomplish this efficiently.

int numbers[10];

Now that we know how to create these arrays, how do we actually use them?

 

int num[50];
