Practical C Programming

How to do it…

1. Let's assume that there is an array, p, with five elements, as follows:

Figure 1.1

Now, suppose you want to enter a value, say 99, at the third position. We will write a C program that will give the following output:

Figure 1.2

Here are the steps to follow to insert an element in an array:

1. Define a macro called max and initialize it to a value of 100:

#define max 100

2. Define an array p of size max elements:

int p[max]

3. Enter the length of the array when prompted. The length you enter will be assigned to a variable n:
